40 Ways we, citizens, can do to combat climate change
Dr Abe V Rotor
Co-Host with Fr JM Manzano SJ, and Prof Emoy Rodolfo, AdMU
Extreme heat is a growing threat due to climate change, and the Philippines has experienced extreme heat in recent years. In April 2024, the Philippines experienced extreme heat, with the heat index* reaching 45°C in Manila and 47°C in Dagupan city. The Department of Health (DOH) classified temperatures of 33–41°C as "extreme caution" and 42–51°C as "danger".

Here are scientific evidences released by the
Intergovernmental Panel on Climate Change
Ninety-seven percent of climate scientists agree that climate-warming trends over the past century are very likely due to human activity since the mid-20th century.
The planet's average surface temperature has risen about 1.62 degrees Fahrenheit (0.9 degrees Celsius) since the late 19th century, with most of the warming occurring in the past 35 years with the five warmest years on record taking place since 2010. The warmest year on record was 2016. The IPCC report continues with these alarming developments:
1. The oceans are getting warmer.
2. Ice sheets are shrinking, especially Greenland and Antarctic. The Arctic sea ice is declining.
3. Glaciers are retreating almost everywhere around the world — including in the Alps, Himalayas, Andes, Rockies, Alaska and Africa (Mount Kilimanjaro),.
4.The snow cover in the Northern Hemisphere is melting at an earlier rate. .
5. Sea level is rising. Global sea level rose about 8 inches in the last century. The rate in the last two decades, however, is nearly double that of the last century and is accelerating slightly every year.
6. Extreme events such as extreme temperature, intense rainfall, and other force majeure
7. The acidity of surface ocean waters has increased by about 30 percent since the beginning of the Industrial Revolution
This global scenario calls for an urgent collective action. It is a plea addressed to governments, organizations, individuals all over the world> It is a plea beyond message of an Internationally famous broadcaster, natural historian and author, David Attenborough. To wit:
"When we look at the rising ocean temperatures, rising carbon dioxide in the atmosphere and so on, we know that they are climbing far more steeply than can be accounted for by the natural oscillation of the weather … What people (must) do is to change their behavior and their attitudes … for our upcoming generation we have to do something, and we have to demand for government support
"Right now we are facing a man-made disaster of global scale, our greatest threat in thousands of years: climate change. If we don’t take action, the collapse of our civilizations and the extinction of much of the natural world is on the horizon".
- David Attenborough, 2018.~

Part 2 - Environmental degradation
is the most serious global abuse
Environmental degradation is the most serious global abuse, not only in pursuit of actual human need, but his unending want of affluence apparently of no end. The earth is slowly choking with deadly gases, its surface defaced and stripped of natural cover, man-made materials dumped on land and water, in fact its geography has changed and continues to be modified directly and indirectly by man.
Dr Abe V Rotor
Bad air over New Delhi, typical in other big cities like Beijing, New York and Metro Manila
industrial boom and millions of cars as affluence rose to the point of ostentatious and frivolous living. But each car’s exhaust is a miniature volcano, erupting daily, worse than a Mt Pinatubo (Philippines) and Mount St Helens (US) combined.
2. The air accumulates gaseous materials and particulates, building acid rain that turns soil acidic and unproductive, defacing valuable works of art (historical relics and artefacts), causing illnesses heretofore unrecorded in medical books, and triggering other diseases as well, including the resurgence of ancient diseases like tuberculosis.
Thinning of the ozone layer over Antarctica. Ozone hole has been detected over the Arctic.
3. The ozone layer, a protective blanket against radiation from space is being thinned by CFC and other gases. A hole at the southern hemisphere as big as continental USA, exposes millions, particularly children, in Australia and New Zealand to ultraviolet rays, a major cause of skin cancer. A smaller ozone hole is building up over the Arctic region.
4. Gases in the atmosphere trap heat from escaping, thus solar heat together with heat generated by the earth and man’s activities collectively contribute to global warming at an alarming rate. Climate change has been the cause of climatic adversities (typhoons, tornadoes, drought, blizzards), erratic weather, and other unexplained atmospheric phenomena.
5. In Al Gore’s “An Inconvenient Truth” the world is getting warmer and warmer at a geometric rate, far exceeding any period of the history of the earth except in its early formation. Warming is traced to increasing amount of CO2 in the air, the principal gas of combustion mainly of fossil fuel that runs agriculture, industry, transportation, and illuminate whole cities around the world.
6, The failure of timely shift to alternative fuel even as fossil fuel sources are dwindling, even as alternative energy is available, even as population demand tremendously increased in the past one hundred years, has grave consequences which we are feeling today, and this is just the beginning - fuel shortage, high cost of living, increasing inequity leading to mass poverty.
7. Environmental degradation is the most serious effect, not only in meeting actual need, but unending want of affluence apparently of no end. The earth is slowly choking with deadly gases, its surface defaced and stripped of natural cover, man-made materials dumped on land and water, in fact its geography has changed and continues to be modified directly and indirectly by man.
8. Reminiscent of the Dust Bowl of the Dakotas in the US in the early 20th century are similar desertification cases, farmlands becoming wastelands due to excessive farming and poor management, such cases include the Sahel region (Africa) struck in the 60s by extreme drought, farmlands around the shrinking Aral Sea (Russia), the source of irrigation now only a measly fraction of its original size. A comparison of Aral Sea in 1989 (left) and 2014 (right)
9. We don’t have to go far. Our own Laguna Bay, bigger than the Sea of Galilee, is dying, its once pristine blue water as I saw it in the sixties as a UPLB trainee in a lakeshore barangay, Gatid, Sta Cruz, is now shallow and muddy as siltation and pollution from homes, farms and industries from four surrounding provinces worsen by encroaching settlements and fishpens clogging the lake – indeed a desecration of the lake’s beauty as described in Rizal’s celebrated novel, Noli Me Tangere.
10. All over the world lakes and rivers are dying: Lake Chad of Africa, Aral Sea of Russia, tributaries of Mississippi in the US, Nile in Egypt, Yangtze in China, Mekong in Vietnam. Who would believe that odor of methane and hydrogen sulphide from the polluted harbour of Hongkong is the first to greet passengers even before landing on the sprawling modern airport? So with tourists on reaching the deck of the 100-storey Sears Tower on Lake Michigan in the US.
Part 3 - Industrialization is Driving Our Climate Wild
“Except for nuclear war or collision with an asteroid, no force has more potential to damage our planet’s web of life than global warming.” Time, Feeling the Heat
Dr Abe V Rotor
There is a ballad sang by Pat Boone, the theme aptly goes like this. “Sometimes, an April day will suddenly bring shower… rain to grow the flowers.”
"Greenhouse gases" mainly Carbon and Sulfur form a gaseous soup in the atmosphere
April in the Northern Luzon is normally the driest of all months. Pag-asa’s record for rain is nil. But a tropical depression may bring along rain that wakes up dormant seeds and make the fields green. But it also douses the fire of the flowers of the fire tree (Regia) and Dapdap (Erythrina)
Here is the mechanism of the greenhouse effect. Let us say that for every ten rays (heat value) of the sun that enter the glass roof, nine are reflected back to the atmosphere, and one is retained in the process. If this is repeated many times over, the inside of the greenhouse becomes hotter than outside. If out of ten ray units, seven are reflected back thereby causing three to stay, the heat buildup is proportionally more rapid and intense.

April in the Northern Luzon is normally the driest of all months. Pag-asa’s record for rain is nil. But a tropical depression may bring along rain that wakes up dormant seeds and make the fields green. But it also douses the fire of the flowers of the fire tree (Regia) and Dapdap (Erythrina)
Our climate is changing for the worse. April may still be the warmest month of the year but, at the same time, we are getting frequent thunderstorms that cause flashfloods and instant traffic jams. Early rains cause grasshoppers to prematurely change colors - brown to green too soon, while proceeding to turn beaches into jellyfish haven.
A Different Kind of Summer
Summer may need a new definition when cicadas fill the eerie summer air, while termites and winged ants swarm before June. The June beetle appears as early as in April. So much summer squash lay in waste in the fields, unharvested because of just one untimely rain. This phenomenon also wakes up the weeds, only to dry up in their juvenile stage. Such false signals of early rain could mean losses of early crops which farmers often plant at the start of the monsoon.
Rainfall is as erratic towards the end of the year as at the beginning. For example, the price of vegetables soared in 2002 when the tail of the monsoon season stayed too long. Onions, garlic, most leafy vegetables, like cabbage and cauliflower, and practically all cucurbits (from ampalaya to cucumber), were adversely affected by unexpected summer rains.
Buildup of Pests and Diseases
Creating a big problem for farmers is the buildup of fungal and bacterial diseases, along with the redoubling of pests. Many organisms, which include insects, nematodes, fungi and bacteria, aestivate during the dry season. Imagine these organisms rising from their dormancy like a sleeping genie, proceeding to attack the nearby plants.
As a farmhand, one notes that when the day is hot and along comes a sudden rainfall, old folks would turn their heads around and, imitating the sound of the house lizard, sigh, “Agparuar manen iti igges.” (This untimely rain is going to breed pests.)
There is something biblical in their prediction, but the scientific basis is that the rain softens the shell of aestivating insects, opens the spores of fungi and bacteria, converting the surrounding environment into one favorable for their growth and development. A sudden rain wakes up a colony of mites ensconced in a curled leaf, incubates a batch of locust eggs buried in the ground, activates resting spores of Pythium (a rot-causing fungus), and softens nematodes tough skin. Considering the short life cycle of these organisms, their mode of infestation coincides with the life cycle of their main and alternate host plants. Whole fields can be destroyed instantaneously.
But plant damage due to physical stress is also just as devastating. Imagine watering your garden on a very hot time of the day. Plant cells are directly damaged by sudden changes in temperature. It also affects the efficiency of osmosis (the intercellular movement of water and dissolved substances from one cell to another), which is vital to the plant’s physiology.
Man-Induced Atmospheric Disturbances
While too much rain falls unexpectedly in one area, there is equally the chance that other areas are not getting enough of it. This is one characteristic of the current global warming, despite of the increase in air moisture in the air by 10 percent in the last two decades. Uneven distribution of rainfall is exacerbated by factors that are mainly man-induced.
Swarm of jellyfish spurred by global warming.
Carbon Dioxide from automobiles and industries is not only increasing the “greenhouse effect”, but is also creating uneven distribution of clouds. As a result we have unpredictable rainfall distribution. When this coincides with El Nino which is a cyclical phenomenon of unusual drought and flooding occurring in opposite places, a severe climatic condition, such as those that occurred in 1972, 1986 and 1995, occur. Crop losses alone over the world ran into billions of dollars.
Industrialization and agriculture have become on the long run strange bedfellows, so to speak. And the irony is that, while agriculture spurred the growth and development of industrialization, it the latter’s by-product – pollution - that is destroying the relationship once conceived to be compatible, thus threatening the lives of millions of farmers all over the world.
Erratic Weather and Pest Buildup
.jpg)
Perhaps not many people know that infestation by migratory pests is enhanced by climatic adversities. But there is a correlation between weather and pest buildup. Migratory locust-(Locusta migratoria manilensis - (Photo) assemble into the migratory phase or what is called swarming, after small groups (congregans) coalesce repeatedly, snowballing into larger and larger populations. This is happening in drought stricken areas where there are patches of green, such as irrigated farmlands and small valleys. As food is consumed quickly with the drought worsening, the insects, in thousands or millions, migrate riding on air currents. Guided by instinct to places where they can find food and a mate, they thus sow famine and human desolation everywhere they visit. Devastations in China, India, Southern United States and Mindanao are not distant memories.
As a witness to the locust control program in Lubao, Pampanga, one notices the lahar-affected areas starting to dry up as solitary locusts pack up into groups and begin attacking sugarcane, the only standing crop soon after harvesting rice and corn. That was 1995, an El Nino year.
Leafhoppers likewise ride on wind currents and could cross the sea that far in spite of their minuscule size. Leafhoppers are carriers of serious diseases of plants such as the dreaded tungro disease of rice that can wipe out a potential bumper crop. Spores of pathogens may also be transmitted this way, not to mention the foot-and-mouth pathogen that affects hoofed animals, blight and rust fungi of crops – and the dreaded influenza virus that affect man.
New Concept of Force Majeure
Even as we bring back to the drawing board technologies from both old and new agricultural schools of thought, we may not be ready for solutions when it comes to an erratic climatic condition. Sometimes we are tempted to redefine force majeure to include vagaries of the climate that nonetheless result into crop failures as destructive as those caused by floods or typhoons. Traditional agriculture is often blamed as the first and easy culprit. In the open Philippine fields, our crops thrive on the mercy of the elements. Advanced countries on the other hand, have improved better facilities (such as drip irrigation and greenhouses) to minimize the effects of potentially unruly weather and changing climate. Even so, the cost of production is increased whenever such measures are used, imputing on the price of the commodity.
Saltwater intrusion into farmlands and rivers, as a result of rising levels of our seas, is not clearly defined under the terms of crop insurance such as those of the Philippine Crop Insurance Corporation (PCIC). The same is true in the case of acid rain, which can wipe out an entire crop, or cause starvation of livestock. But with climatic conditions predisposing animals to foot-and-mouth diseases, as well as crop destruction through climate-induced pest buildup, insurance companies still have to rewrite their contract to have these claims covered.
Acid Rain
It is not only on the pattern and volume of rainfall distribution that bother us. On a number of occasions, this writer has seen field crops, lawns and gardens scorched by acid rain. Acidic reaction is manifested primarily by lesions of leaves with the leaf buds first affected, followed by gradual drying up around these spots under the heat of the sun. Either leaves dry up, or the whole plant defoliates, but in extreme cases trees suffer of dieback, which is the drying of growing tips of branches. Many plants do not recover from this stage, especially during summer, thereby providing the fuel for spontaneous forest fire.
As we continue to spew noxious gases (such as sulfur and carbon dioxide) into the air, water molecules bind with the sulfur or carbon radicals, to form acid rain. The spiked water molecules condense into rain, reaching up to acidity levels of 4 pH. Most plants thrive best within neutral 7 pH. In acidic soils, plant nutrients become locked up, so that even soils that are fertile do not produce a good harvest as expected unless their pH is adjusted to normal range. This requires a tedious and expensive rehabilitation effort.
___________________________________________________________________
The increasing cases of climatic adversities endorse a re-definition of force majeure which shall serve as guide to banks and insurance companies. Meanwhile, planners are urged to go back to the drawing board to review current agricultural technologies, and land use policies. At the same time, more and more farmers are cultivating crops under greenhouses and other controlled conditions such as drip irrigation, zero tillage and natural farming to get rid of chemicals deleterious to human health. As this is done, 86 countries, signatories to the 1997 Kyoto Protocol (except the US), are working to effectively curve the deteriorating conditions of the earth’s atmosphere.

Plants have different water, CO2 and temperature regimes
What are the effects of changing climate on plants? First, it is important to classify plants according to their water requirement. There are those that thrive best under dry condition, the xerophytes, such as those living in the desert, while others are water loving such as rice. Even our common crops are classified according to various levels of water regime, so that any significant change in their water supply greatly affects them.
Imagine that as the sea level rises, more and more areas become flooded. According to the Intergovernmental Panel on Climatic Change (IPCC), much of the shorelines we know today will vanish if sea levels rise as predicted by computerized models. There will be changes in natural vegetation and it will be necessary to plan out cropping systems to fit into the changed landscape. The job would be as crucial as adjusting cropping systems with increasing temperature and Carbon Dioxide concentration.

There will be changes in natural vegetation and it will be necessary to plan out cropping systems to fit into the changed landscape. The job would be as crucial as adjusting cropping systems with increasing temperature and Carbon Dioxide concentration.
In a research conducted at the UST Graduate School, with Dr. Reynaldo Tabbada as adviser, any increase in CO2 concentrations from present levels estimated at 350 ppm, may be favorable to the early post-germination development of mungbean, a typical representative of legumes. Cereals also respond favorably to raised CO2, but it is the expected doubling of CO2 levels within the next 70 to 80 years that causes us some apprehension.
Flooding also contributes to the increase in methane gas production as a result of expanding swamplands. Wider areas are likely to be planted to rice as the rate of precipitation increases. Rice culture is known to contribute significant amounts of methane gas into the atmosphere.
The levels of carbon dioxide, nitrous oxide and methane gas have jumped 30 percent, 15 percent and 100 percent, respectively, from pre-industrial levels. All these indicate that our atmospheric blanket is getting thicker and heavier, and that more heat is being trapped. Even with holes in the ozone layer atop the Antarctic region, and lately on the Arctic, the earth cannot sufficiently dissipate the heat to a state of balance.
A average increase of a mere half degree Celsius in global temperature noticed during the last century may be dismissed as “slight” were it not for the consequences felt in alarming proportions, such as the heat waves. Even with the use of models, the global temperature will continue to rise from a low estimate of 1.4 degrees Celsius to as high as 5.8 degrees Celsius by year 2100. This is 50 percent higher than predicted only a few years ago.

Except in acclimatization studies, heat tolerance is something we have not given much attention to in our current crop researches. What we usually do is to assign plants to different temperature regimes, with broad classifications, such as tropical, temperate, or semi-tropical and semi-temperate. As global temperature builds up, the frontiers of agriculture will move northward to occupy areas normally too cool for certain crops to grow. Tropical crops on the other hand will follow suit, in effect replacing temperate crops.
Primer on Greenhouse Effect
Primer on Greenhouse Effect
Many of us must have heard the term “Greenhouse Effect” many times to a point that it has become part of the dictionary. Greenhouse effect is an analogy. And there is no simpler way to illustrate the “trapping” of heat inside a closed chamber such as a glass house where plants are raised even if the weather outside is unfavorable for plant growth and development. Greenhouses are not as popular in the tropics as they are in temperate countries. In these places, winter is severe. Sometimes it comes early as in a frost and the plants perish before they are harvested.
Here is the mechanism of the greenhouse effect. Let us say that for every ten rays (heat value) of the sun that enter the glass roof, nine are reflected back to the atmosphere, and one is retained in the process. If this is repeated many times over, the inside of the greenhouse becomes hotter than outside. If out of ten ray units, seven are reflected back thereby causing three to stay, the heat buildup is proportionally more rapid and intense.
Our atmosphere is like a greenhouse, its roof is the atmosphere. When the sun strikes the earth, the atmosphere retains the heat for sometime, otherwise our planet will be cooler than it is now. It is this heat level that maintains a climate favorable to life as we know it. When it is cold we need a blanket to keep us warm. Similarly the atmosphere serves as a blanket for our planet.
This blanket is not at all fixed and stable; it had undergone changes in the past. The last Ice Age was preceded by a decrease of our atmospheric temperature, a phenomenon that had recurred cyclically during the succeeding millions of years. It is only at this time, at the advent of industrialization that man’s activities have definitely influenced the structure and behavior of our atmosphere.
In his masteral thesis, “Global Warming: Its Ethico-Theological Implications,” presented to the UST Graduate School, Fr. Allan M. Otodoy, concluded that the expansion of the greenhouse effect is a clear sign that modern civilization is on a destructive path. It raises ethical questions of environmental issues that all of us need to know and ponder upon.
We have tinkered, and continue to tinker, with our natural environment such as in the way we use energy, principally fossil fuel. By so doing, we alter, if not destroy, the ecosystem. We as a species always aimed at satisfying our needs and wants, while elevating our standards of living without regard for the finite resources of the earth.
Additionally, we have been indifferent to confront the problems of inequality in the distribution of these resources – agricultural and industrial, and well, natural resources – those we often consider as free. Poverty contributes as much to the degradation of out environment as the creation and use of goods and services that only the affluent can afford.
Industrialization has erased much of our gains in agriculture, and has negated our efforts to preserve the environment. We cannot have the best of two worlds, but we can come up with a formula of development that best serve mankind. x x x

Part 4 - Understanding the El Nino Phenomenon, Cause and Effect
El Niño and La Niña events occur every two to seven years, on average, but they don't occur on a regular schedule. Generally, El Niño occurs more frequently than La Niña. A new study found global weather events caused by El Niño will likely become more frequent within the next two decades regardless of any reduction in carbon emissions, which could drastically affect weather patterns around the world.
Extreme drought brings rice farming to a halt, Cabanatuan, Nueva Ecija, 2010
But first, let me clear El Nino, who to us Filipinos is most endeared in our hearts and homes, referring of course to the Child Jesus. The name was coined in Spanish when the descent of warm water along the coast of Peru and Argentina overcomes the ascending cold current causing massive rainfall and flooding. The phenomenon report coincided on Decmber 25.
A timeline of all the El Nino episodes between 1900 and 2016. It is thought that there have been at least 30 El Niño events since 1900, with the 1982-83, 1997–98 and 2014–16 events among the strongest on record. Since 2000, El Niño events have been observed in 2002–03, 2004–05, 2006–07, 2009–10 and 2015–16.
--------------------------------------------
Major ENSO (El Nino Southern Oscillation) events were recorded in the years 1790–93, 1828, 1876–78, 1891, 1925–26, 1972–73, 1982–83, 1997–98, and 2014–16 with the episodes being among of the strongest ever. Since 2000, El Niño events have been observed in 2002–03, 2004–05, 2006–07, 2009–10, 2014–16, and 2018–19.
-------------------------------------------
Death of livestock, other animals and wildlife, engraving
El Niño events are thought to have been occurring for thousands of years.The biblical story of the 10 Plagues of Egypt is believed to be associated with El Nino, and possibly coincided with other natural disasters such as the eruption of Mt Vesuvius. The death of livestock spawned hordes of flies that caused the outbreak of boils, and triggered sudden increase in frog population. This was favored by the abatement of the Nile River's flow, which in turn caused dinoflagellates to bloom (algal bloom) with the characteristic blood-red color which we term today as Red Tide.
Ocean currents of the world. El Nino Phenomenon originates at the South Pacific Equatorial Current (counterclockwise) on the Southern hemisphere as shown at the left of this map. This is where the "anomaly," a deviation of the normal oscillation (El Nino Southern Oscillation or ENSO) which occurs as a cycle every 3 to 7 years. Note the distance of the Philippines (top right). But how are we affected by the El Nino Phenomenon?
But first, let us visualize with the diagram (LEFT), the passing of seasons. The sun is most intense where it directly strikes the earth. Thus Summer in the northern hemisphere (left) is the hottest season and December (right) the coolest. There are two equinoxes when the rays of the sun strike the earth midway: Spring (beginning in March, top) and Autumn (beginning September, bottom). Temperate countries have pronounced seasons. The Philippines experiences only two seasons: wet (June to October/November) and dry (December to May). El Nino is most severe in the dry season which we are presently experiencing.
Normal year showing balanced flow of ocean current.
El Nino year scenario. A massive mass of water 7 degrees hotter than surface water forms a wall deflecting the cold current on both sides. This warm current moves downward along the western coast of South America, arriving by December 25, thus named El Nino.
El Niño events occur irregularly at intervals of 2-7 years, although the average is about once every 3-4 years. They typically last 12-18 months, and are accompanied by swings in the Southern Oscillation (SO), an interannual see-saw in tropical sea level pressure between the eastern and western hemispheres
The warm mass of water becomes so extensive it create a phenomenon of excessive rainfall and flooding in the geographic region of South America (white area). On the other side of the globe, it is warm and dry.
Here is a meteorological satellite graphical presentation showing the effects of El Nino worldwide. Originally El Nino refers only to those experiencing extreme dry and hot conditions, until recently, to differentiate areas experiencing excessive rainfall and flood, the term La Nina was coined. Thus after an El Nino period, and the same area receives this time extreme wet conditions, scientists call it El Nina. Thus El Nino and La Nina may be occurring in different regions shown on the map. A place may experience alternate phenomena.
-----------------------
It is thought that El Niño affected the Inca Empire in modern-day Peru, who sacrificed humans in order to try and prevent the rains.
----------------------Let's not take El Nino for granted. The North Cotabato farmers' uprising was precipitated by hunger. It is ironic that farmers themselves led the uprising which resulted to two deaths, several injuries, and imprisonment of more than a hundred which included senior citizen and pregnant women.
Flooding caused by La Nina
The major 1982–83 El Niño led to an upsurge of interest from the scientific community. The period 1991–1995 was unusual in that El Niños have rarely occurred in such rapid succession. An especially intense El Niño event in 1998 caused an estimated 16% of the world's reef systems to die. The event temporarily warmed air temperature by 1.5 °C, compared to the usual increase of 0.25 °C associated with El Niño events. Since then, mass coral bleaching has become common worldwide, with all regions having suffered "severe bleaching".
2021 one of seven warmest years on record despite La Nina’s cooling effect. Experts say collation of six major datasets shows 2021 was seventh year in a row with temperatures more than 1C above pre-industrial times. ~
--------------------------------------------------------------------------
El Niño events of 1982-83 and 1997-98
were the most intense of the 20th century.
During the 1982-83 event, sea-surface temperatures in the eastern tropical Pacific were 7.8-12.8° C (9-18° F) above normal. These strong temperature increases caused severe climatic changes: Australia experienced harsh drought conditions; typhoons occurred in Tahiti; and record rainfall and flooding hit central Chile. The west coast of North America was unusually stormy during the winter season, and fish catches were dramatically reduced from Chile to the U.S. state of Alaska.
The El Niño event of 1997-98 was the first El Niño event to be scientifically monitored from beginning to end. The 1997-98 event produced drought conditions in Indonesia, Malaysia, and the Philippines. Peru experienced very heavy rains and severe flooding. In the United States, increased winter rainfall hit California, while the Midwest experienced record-breaking warm temperatures during a period known as “the year without a winter.”
Diseases thrive in communities devastated by natural hazards such as flood or drought. El Niño-related flooding is associated with increases in cholera, dengue, and malaria in some parts of the world, while drought can lead to wildfires that produce respiratory problems.

Part 5 - Kiribati: Vanishing Paradise
Rising sea level is forcing inhabitants to leave permanently their home islands, a classical example of modern day exodus - ecomigration.
Dr Abe V Rotor
Kiribati main island is formerly Atoll Christmas, named by Captain Cook when he arrived on Christmas Eve in 1777. The island, like most islands in the region, faces irreversible submergence and sea water intrusion as a result of rising sea level brought about by global warming. The island was used as nuclear testing ground by the United States in the fifties and sixties.
Aerial view of the Kiribati group of islands. Rising sea level is forcing inhabitants to leave permanently their home islands, a classical example of modern day exodus - ecomigration. Displaced inhabitants are being settled mainly in Australia, New Zealand and Papua New Guinea.
The sea has practically swallowed up a whole atoll*, with narrow
fringes the only remaining habitable portion, at least up to now.
Kiribati Parliament House is threatened by receding shoreline
(background) and rising lagoon (foreground).
Kiribati (pronounced /ˈkɪrɨbæs or KIRR-i-bas; Gilbertese: [ˈkiɾibas]), is composed of 32 atolls and one raised coral island, dispersed over 3.5 million square kilometres, (1,351,000 square miles) straddling the equator, and bordering the International Date Line at its easternmost point. Kiribati is the only country in the world located on both hemispheres and lying on both sides of the 180th meridian.
The groups of islands are:
* Banaba: an isolated island between Nauru and the Gilbert Islands
* Gilbert Islands: 16 atolls located some 930 miles (1,500 km) north of Fiji
* Phoenix Islands: 8 atolls and coral islands located some 1,100 miles (1,800 km) southeast of the Gilberts
* Line Islands: 8 atolls and one reef, located about 2,050 miles (3,300 km) east of the Gilberts.
Caroline Atoll channel between west side of Long Island and Nake Island.
Used for nuclear testing in the 1950s and 1960s, the island is now valued for its marine and wildlife resources. It is particularly important as a seabird nesting site—with an estimated 6 million birds using or breeding on the island, including several million Sooty Terns.
According to the South Pacific Regional Environment Program, two small uninhabited Kiribati islets, Tebua Tarawa and Abanuea, disappeared underwater in 1999. The islet of Tepuka Savilivili no longer has any coconut trees due to salination. The UN Intergovernmental Panel on Climate Change predicts that sea levels will rise by about half a metre (20 in) by 2100 due to global warming and a further rise would be inevitable. It is thus likely that within a century the nation's arable land will become subject to increased soil salination and will be largely submerged.
Rising level level is also being felt in many countries, particularly island-countries like the Philippines. ~

- Economy- Until 1979, when Banaba’s deposit of phosphate rock was exhausted, Kiribati’s economy depended heavily on the export of phosphate mineral. Before the cessation of mining, a large reserve fund was accumulated; the interest now contributes to government revenue. Other revenue earners are copra, mostly produced in the village economy, and license fees from foreign fishing fleets, including a special tuna-fishing agreement with the European Union. Commercial seaweed farming has become an important economic activity. Internet
Part 6 - Some Detrimental Effects of El Niño Drought
Seedlings of Ilang-ilang (Cananga odorata) and Sweet Tamarind (Tamarindus indica) wilt under the punishing sun, exacerbated by the heat evolved by the concrete pavement. Daily watering is needed in the morning and afternoon.
Malunggay trees (Moringa oleifera) appear to withstand the current drought and excessive picking of their leaves by passersby. Their trunks have been cut into stumps to give way to street lighting and cable installation.
Kamote (Ipomea batatas) is predisposed to Sweet Potato weevil (Cylas formicarius)under extreme heat. The pest renders the tubers totally unfit to human and animal consumption.
Anahaw (Livistona rotundifolia) becomes an alternate host of Rhinocerus Beetle (Oryctes rhinocerus) in the absence of its regular host - coconut. The pest has been emboldened by continuous and heavy spraying of vegetables and other crops in the area.
Used plastic sacks left in the farm to "decay" under direct sunlight and continuous irrigation disintegrate into microplastic which is deleterious to health and the environment.
Brooding hen finds refuge to hatch her eggs inside a broken jar (burnay Ilk) while outside temperature is unbearable.
Talisay (Terminalia catappa) barely retains its leaves, while a Camachile tree (Pitecolobium dulce) succumbs to the El Niño phenomenon, the worst in many years this current year 2024.
Acacia trees (Samanea saman} now skeletons in the sky, and a new beginning and resolve with the young generation led by co-ed Angie Tobias. ~
Part 7 - Ten Naturally Occurring Cycles
Naturally occurring cycles govern the physico-chemical interactions of the earth’s chemical elements and compounds, principally Carbon, Hydrogen, Oxygen and Nitrogen (CHON), which are essential to life.
Dr Abe V Rotor
. Lightning is Nature’s quickest and most efficient converter and recycler, instant manufacturer of nitrates, phosphates, sulfates; it burns anything on its path, recharges ions. Lightning sustains the needs of the biosphere, it is key to biodiversity.
2. Fire is the Nature’s second tool. While fire is indeed destructive, in the long run, fields, grasslands and forests are given new life by it. Fire is a test of survival of the fittest. It is the key to renewal and continuity of life.
3. Volcanoes erupt to recycle the elements from the bowels of the earth to replenish the spent landscape, so with submarine volcanoes that keep the balance of marine ecosystems.
4. Natural cycles prevail with the seasons, weather and climate. They govern the life cycle and alternation of generations of organisms; the food chain, food web, and food pyramid. The same applies to long term phenomena such as Continental Drift and Ice age.
5. Naturally occurring cycles govern the physico-chemical interactions of the earth’s chemical elements and compounds, principally Carbon, Hydrogen, Oxygen and Nitrogen (CHON), which are essential to life.
6. Nature recycling of organic materials in through the action of microorganisms: bacteria, algae, protists (amoeba, diatoms), fungi, blue green algae. Fibrous materials are broken down by fungi. Other than roughage and fuel, rice hay is used as substrate for mushroom growing. The spent materials decompose easily into organic fertilizer.

7. Biological (e.g. Trichoderma, a fungus, to hasten composting; termites on wood); Enzymatic reaction (e.g., wild sunflower in composting, urea in hay}; Mechanical (shedding, grinding); Fermentation (silage, retting, biogas digester)
8. Recycling by animals also helps in controlling the destructive ones such as the mosquito, which is food of fish, spider and bat.
9. Nature’s nutrient converters. Simple life forms such as lichens, algae, mosses and ferns silently work on inert materials, convert them into nutrients for higher organisms.
10. Nature’s recycling with waterways Mekong river in Vietnam (below), Pasig River in the Philippines, Great Britain, Danube and Rhine in Europe, the Nile, Mississippi, Amazon, Yangtze, Tigris-Euphrates. Rivers, lakes, swamps, basins – they provide many basic needs of man. They are arteries of life, the ecological bridge between the living and the non-living world. It is said that no civilization exists without a river.
Snails and crustaceans are nature's aquatic janitors.
Goats and pigs have tremendous appetite. They eat a wide range of food not suitable to other organisms.
Lake Tikob is a self-contained ecosystem, a natural sinkhole.

Part 8 - Global Warming is Creating Superbugs
Dr Abe V Rotor
Living with Nature School on BlogTermites ready to develop wings and emerge into swarms come rainy season. Global warming has emboldened termites to attack homes and forests. (Photo taken at Parks and Wildlife Nature Center)
Gamu-gamu or simut-simut.
These are the winged termites. These ordinarily shy, tunnel-dwelling insect suddenly take into the air at night in a swarm, attracted by light in our homes and towns. There is a new breed of super termite that has destroyed thousands of homes in Southern United States since the 1950’s after it was accidentally introduced from China. The insect continued to develop resistance to eradication despite U.S. advances in biology and chemistry.
We trace this superb resistance on two views. First, this super termite is the survivor of chemical spraying. Pesticides may have eradicated the weaker members of its population, but the survivors carry the acquired resistance. After several generations, and the super termite was formed. This genetic advantage may explain the species’ survival, but what about its successful geographic adaptation and distribution? This brings us to my second observation.
Frequent rains and floods predispose wood to soften or even rot, making it more palatable to the cellulose-eating insect. It prefers old wood and the southern states have houses as old as the Mayflower expedition. These conditions provide a perfect termite abode, and together with its symbionts, protozoa in its stomach and wood fungus as pre-digester, termite empires continue to spread from one house after another.
Then at swarming time (which now occurs more frequently than once a year), it is easy for a new termite swarm to start new colonies, which today can be as convenient in book shelves, wooden appliances, apparadors, and office files, as well as posts, beams, floors and walls. And by the way, according to Discovery TV channel, termites strangely eat twice as fast, given an ambiance of loud metallic music (or noise). Watch out for the floor!
The Case of the Fire Ant
We encounter red ants, Solenopsis geminata, in the kitchen, picnic grounds, and garden. According to old folks, when they emerge from their nest to seek shelter on higher grounds, carrying their young and food, they proclaim the arrival of heavy rain.
But it is not this kind of ant of which we are more concerned now. In Florida, a super red ant has spread all over the state and is still moving via floodwaters. A mass of ants, by the thousands, would simply float on water currents landing on a new territory, and then break into several colonies. That is how efficiently the ant is spread, a new adaptation that other ants do not possess.
The sting of this super ant contains a poisonous formic acid. A person who is allergic to it could die from just a single sting. While this ant may be beneficial in one way by devouring destructive insects on the farm, the very sign of its presence in such magnitude is alarming. The US Department of Agriculture even uses GP (Global Positioning) Satellite to monitor and identify the foragers’ locations and sizes of their colonies to assist in their eradication.
The Case of the Super Bacteria
In 1993, tens of thousands of people in Milwaukee suddenly got sick and the suspected culprit is a bacterium that lives in the cloudy waters of Lake Michigan which supplies the areas’ potable water. But Lake Michigan has long been polluted. From the view deck on Sears Tower, one can smell the foul odor of the lake. What is surprising is that the pathogen has found a way to defy ordinary water treatment methods.
Such is how the Milwaukee pathogen has proliferated. During the El Nino of 1993, melting snow joined the floodwaters, washing down animal manure and other organic wastes from upland farms and homes, and dumping them into the lake. This has the effect of fertilizing the bacterium. Ecologists call this sudden bacterial upsurge “bloom”, which is similar to the algal bloom phenomenon.To control the epidemic, drinking water had to be boiled, and water treatment methods intensified until the bacterium is eliminated. These procedures are necessarily very costly operations.

Part 9 - Meteorology and Allergy
Weather and allergy forecast the conditions of the environment,
and health.
World Meteorological Day was established in 1951 to commemorate the World Meteorological Organization creation on 23 March 1950. This organization announces a slogan for World Meteorological Day every year, and this day is celebrated in all member countries.
“We must have something to cling to. Some things must not change.” – Dr Arturo B Rotor ( Dr Rotor, The Quiet Observer by Lily Lim )
Abercio V Rotor, Ph.D.1. Greetings: Dr Maria Carmela Agustin-Kasala (PSAAI President), Dr Rommel Crisenio Lobo, (Convention Chairman); Mr Nathaniel “Mang Tani” Cruz; members of the Philippine Society of Allergy, Asthma and Immunology, guests, ladies and gentlemen. Good Morning.
2. First of all, I would like to convey our sincerest thanks and gratitude to Philippine Society of Allergy, Asthma and Immunology on behalf of the Rotor clan, for honoring the late Dr Arturo B Rotor in this biennial convention. The theme of this convention Allergy UPdates and INnovations is most appropriate to the thrust of Dr Rotor’s research and teachings which he advocated in his lifetime.
Dr Arturo B Rotor (1907-1988)
3. It’s an opportunity to meet Mang Tani in person who is the leading meteorologist on media today. On the Internet I read Mang Tani’s definition of meteorology when he was applying for a job. Meteorology is the study of stars and meteors. It is original, brief. holistic - and I say, a philosophy.
4. Meteorology connects human life with the stars for hopes and dreams. It reminds us of human vulnerability when stars fall, when a meteor appears in the sky, which old folks associate with unfortunate events like natural calamities and war. Listening to Mang Tani makes us aware of our relationship with Nature – and our relationship with Nature brings us closer to our Creator.
5. It reminds me of a story about an unbeliever, a professed atheist. One stormy afternoon while he was walking with a friend, a thunderbolt struck close to them. The atheist automatically made a sign of the cross. His companion was surprised and asked. “I thought you don’t believe in God?” “Pare (friend) reflex action lang ‘yan.”
I asked the fellow who told me this story kung may pinagbago siya. Did this atheist change after this experience. He never made the sign of the cross again? No, he returned to his faith and found God again.
6. The focus of this story is the other person. Yun hindi natakot. Wala lang sa kanya ang kidlat, Wala lang ang bagyo at baha. Acid rain, El Niño, and other vagaries of Nature. Like in the parable of the Prodigal son, the bigger problem perceived in our present is the other son, who was obedient but cold and indifferent. Wala lang ang pagbalik ng kanyang kapatid.
7. We cannot be the wala lang brother on issues of the environment today. A weather report is not just news. It is a warning. It calls for reform. It is a challenge. Can we go back to the CO2 level in the air 50 years ago? (An Inconvenient Truth by Al Gore) Can we arrest global warming. Can we reduce the chances of wild fire? Prevent flood?
8. What makes weather is the result of interacting conditions of the environment. When considered over a length of time and within a particular region which we call climate - we ask the same question. Today’s modern – or postmodern - living is an unending pursuit of the Good Life. It can’t be that weather is the making of Nature alone. Weather today is greatly influenced by man. Climate change is traced to industrialization, urbanization, population explosion, etc.
9. Ang buhay ay weather, weather lang.” may just be an expression. It is deceiving. It cannot erase man’s responsibility and accountability to Nature and ultimately to our Creator. We are largely to be blamed for global warming, the ozone hole, increasing frequency and strength of typhoons, hurricanes, tornados, rising sea level, etc.
10. And the problem of pollution is in the hands of everyone of us. It is easier said than done to Reduce, Replace, Regulate, Recycle, Replenish. More so to reserve for the next generation. And what is the missing R, which is primordial, which brings us together in respect and harmony? Revere. Reverence for life.
11. Mang Tani's lecture urges us to give more importance to environmental medicine. Environmental Medicine, the most practical and original to the point of being primeval approach, if I may say so. Its rules are universal and as natural as Nature’s laws. It is dependent on ecological principles in the conservation of a clean and balance environment. It is complementary to conventional medicine, modern medicine. And Alternative medicine, being part of Filipino culture and closest to local remedies, time-tested and practical remedies - the mainstay of folk medicine which caters to the grassroots.
12. If we revere somebody or a thing we care for him, we care for that thing. Caring is more than loving. Caring is a sacred act because we are concerned with the well-being of a person or thing. To take care of a tree, is more than loving it. Reverence for life is a philosophy. Advocates of this philosophy are Rachel Carson, Albert Schweitzer, Charles Darwin and our very own Jose Rizal. The ecological concept of sin and formative conscience are changing the way we profess our faith, our reverence towards the Almighty, paradigm of salvation.
------------------------------------------
Meteorology takes us closer not only to the stars but to heaven where that Great Almighty watches our world, our lives, at the way we make use of His gifts, particularly rationality which He gave only to man. His greatest expression that brings us altogether as one globally integrated ecosystem is Nature. Nature is God’s greatest expression of love and harmony.
------------------------------------------
13. Quite often the enemy is ignorance, and the real enemy is no other than us, ourselves. Which leads as to ask ourselves, “Are we doing our part as guardians and custodians of our Planet Earth.” I see head moving, - more sideways that nodding. Meteorology is an important catalyst to know more about nature. Whatever may be our beliefs, race, affluence, all of us young and old. Aware and keen at the ways of nature is a bridge to knowing nature’s laws and principles – tulay – and it must be strong to carry across millions of people towards gaining functional knowledge on how to live in our natural environment properly and peacefully.
14. There is a saying that the two things we cannot escape in life are death and taxes. It is just one of the witty expressions. There is a third one, and it is the most important in our postmodern times - formative conscience. It takes us out of a syndrome of neutral morality. When we spew gas into the air, we contribute to global warming. We contribute to the occurrence and spread of various ailments, including allergy. We supply the ingredients of acid rain that destroys crops. Our airlines stir the atmosphere into typhoon and flood. Imagine how many millions of small volcanoes erupt daily from the tailpipe of our cars and chimneys of industry. Put together worldwide is it surpasses Mt Pinatubo erupting continuously.
15. As I watch Mang Tani on TV I could sense that he is addressing not only THE person, but the inner person. We cannot escape from that inner person in us – The Little Prince in Antoine de Saint-Exupery’ book. We are not only responsible, we are also accountable for our actions and inactions, and time is running out that we ourselves are victims of self-destruct, which in biology is called autotoxicity,
16. I would like to address these thoughts to the theme of this convention: Allergy Updates and Innovations. On the point of view of medicine – conventional, modern, and environmental, it is the third – environmental medicine - that Mang Tani has brought its awareness into this hall. On the other hand, his paper urges us to look beyond this hall, to learn to live simple and honest, and to be friendly with Nature.
17. Meteorology makes people aware that they are part of nature and nature a part of them. Living friendly with Nature means less frequency and strength of typhoons, cleaner air to breath, less smog that blankets cities, cleaner rivers and lakes for more fish, less fear and anxiety about weather disturbances. Lower CO2 level, less acid rain, shrinking of the ozone hole and less cosmic radiation. A great relief from human health problems– on all aspects –physical, mental and emotional. How we wish better peace and order, more time with the family, return to the humanities, the classics in music and literature, How we wish there were new Amorsolos , Abelardos, Dimalantas, and humility aside, more Arturo Rotor doctors.
Not only as a reliable forecaster of the conditions of the atmosphere Mang Tani is a teacher. Teachers aim for the stars. Stars guide people to dream, stars make people happy. Stars make beautiful song and poetry that give meaning to life as well as quaintness of living. Teachers know how to separate the grain from the chaff, so to speak, opinion from facts, true and fake news, superstition from reality. That meteors are not apocalyptic they make us look at heaven, too.
18. CONCLUSION; Weather and allergy are both barometers, they forecast the conditions of the environment, and that of health, respectively. Scientists behind meteorology like Mang Tani, and doctors attending to allergy cases see to it that they warn their audience and patients to take heed of the warning. And most important they mobilize people into action, individually and collectively. It is the latter that creates cooperation, love and compassion.
Lastly, and it is the most important. If we protect nature, live up with her laws and ways, revere creation, our environment will be kept balanced, people will be healthier, there will be less man-induced calamities, and the world will be a better place to live in for our generation, and especially the next generations if only we do our part, Change must start somewhere. And it starts here in this hall and we carry it outside after this convention.
Thank you to Mang Tani, to PSAAI, and all those who made this gathering successful. Again on behalf of the Rotor clan, associates and friends of the late Dr Arturo B Rotor Maraming, maraming salamat po.

Dr. Arturo B. Rotor, the first Filipino Allergist, tells us that the human being should be regarded holistically, therefore too, when it comes to attending to his health – body and spirit, psyche and intellect. And we realize that man is truly divine with these attributes: Man the Thinker (Homo sapiens), Man the Maker (Homo faber), Man the Player (Homo ludens) and the Man the Reverent (Homo spiritus). Dr Rotor was revolutionary in his own right and time.

Part 10 - Read Nature. You will enjoy life, live healthier and longer.
Dr Abe V Rotor
Can we predict wildfire before it starts, more so to strike our area?

Read Nature. You will enjoy life, live healthier and longer. You'll gain more friends and respect from people. Above all, you will be at peace with yourself and with your environment.
Rain is coming, take heed! Hovering dragonflies, aggressive biting of mosquitoes, ants on the move carrying their young and provisions.
Here are some biological signs to watch. They are Nature's barometer, so to speak; Nature's clock, Nature's way of communicating with the living world.
1. Mad dog – Its tail is tucked underneath; animal restless biting at anything within its reach; froth coming from its mouth; stealthily moves about without any apparent direction; dreads the presence of water (hydrophobia);usually occurs during hot days particularly in summer. Be keen; keep distance; notify others of danger; get help.Dogs must be vaccinated with anti-rabies and not allowed to go in the street. (Nikko, our pet at 15 before he died of old age.)
2. Drought – Occurs in summer; landscape scorched; dry river beds and ponds; brush fires occurs; lake water recedes; crack on earth, especially areas under water in monsoon; worst scenario - flowering of bamboo usually during El Nino, a phenomenon that happens every 7 to 10 years.
Leaves oft talisay (Terminalia catappa) turn orange to red before falling to the ground, a sign that the Amihan (cold season) has arrived.
3. Earthquake – Farm animals restless; horses kick and neigh; pigs snort; fowls abandon usual roost; turkey cackle; cattle seek exit from corral; dogs howl; and the like. Wild animals abandon abode – snakes come out into the open; reptile keep out of the water; elephants defy their master’s command; birds abandon nest, other emigrate.

4. Typhoon – Doldrums-like calm; uneasiness to both humans and animals as barometer reading drops which means atmospheric pressure goes down; arthritis and hypertension symptoms are felt by sensitive persons. As typhoon approaches, sea becomes rough; sky overcast; clouds move fast to one direction; gusts of cold and warm wind, thunderstorms.2.jpg)
5. Influenza – Precipitated by alternate cold and hot weather, thunderstorms, abrupt change in season. Influenza season is usually at the onset of amihan as the habagat comes to an end. Practical signs: people coughing in church and other gatherings; sale of cold tablets and antibiotics is up; hospitals full. Epidemic starts in the family, neighborhood, local community; also, in schools, malls and markets, and may spread to cover a city or district or province. Modern transportation has made spread of flu easier and wider.
6. Pristine Environment – Abundance of lichens on trunks and branches of trees, rocks, and soil. There are three types: crustose (crust), foliose (leaf-like) and fruticose (fruiting type). They are biological indicators of clean air. The ultimate test is the abundance of the fruticose type.
7. Inclement Weather – Halo around moon; gray and red sunset; a storm may be coming depending upon the intensity of these signs.

8. Rain - Dragonflies hovering; aggressive biting of mosquitoes; ants move to another place carrying their young and provisions. The latter predicts heavy continuous rainfall or siyam-siyam or nep-nep. Herons on the move heralds the monsoon.
9. Monsoon – Frogs croak; insects (termite, ants) swarm; lightning and thunder get frequent; first heavy rain in May vegetates the landscape, thus turning from brown to green. It comes early or late, but usually in later part of May. Global warming has brought unpredictable signs indicating that our climate is changing.
10. Ripening of Fruits – Generally from green to yellow to orange (banana, orange, apple, etc. Determined by smell: guava, jackfruit, durian, melon, etc); shiny rind (caimito, siniguelas). Dull skin (chico), enlarged ridges and furrows (atis, guayabano, anonas)
Can you read other signs?
1. Sweetness/sourness of fruit
2. Maturity and succulence of vegetables (okra, cucumber)
3. Tenderness of nut (buko, macapuno)
4. Sweetness and maturity of fruit (watermelon)
5. Time to harvest singkamas, onions, garlic, sugar beet
6. Presence of jellyfish
7. Red tide season
8. Coming flood (earthworm abandon their burrows.)
9. Time to harvest palay, corn, wheat.
10. Slippery walkway (presence of algae and scum)
11. Depth of water (by color, sound of oar, current, clarity)
12. Cloud reading of weather.
13. Glassy eyes (deep feelings like hatred, or “wala sa sarili”)
14. Wrinkles at the corner of eyes (happy disposition)
15. Furrows on forehead (problematic)
16. Rough hand (worker, also athlete)
17. Brilliant and attentive eyes (intelligence)
18. Clumsiness, strumming (nervous, uncertain)
19. Heavy feet (angry, lazy)
20. Tight jaw (angry, restlessly active)
Open Forum:
1. How reliable is “gut feel”
2. How about ESP?
3. What is “aura?” How does it apply to relationships?
4. What is Biological Clock? Name how it affects your life.
5. Life starts at 40 – how do you interpret this?
6. What are prophets to you? Are there people who can see the future?

When earthworms crawl out of their holes and search
for higher grounds, it is a sign that a flood is coming.
