Part 2: Global Warming Disturbs Our Climate

Here is a background on global warming and its impact on our atmosphere (air), lithosphere (land) and hydrosphere (water).

1. During the 20th century, the average atmospheric temperature went up by at least one degree Fahrenheit. Small as it seems, this rise in temperature is sufficient to activate tornadoes, hurricanes, rains and floods. It also helps widen temperature range to extreme levels, creating abnormalities in weather conditions. Scientists explain why the El Nino phenomenon (which comes every five or ten years) is becoming more and more erratic, causing much destruction, especially when it is too wet on one side of the globe, and too dry on the other.

2. The reason why our atmosphere is getting warmer is because of the so-called greenhouse effect, which means that more of the heat of the sun is absorbed and stays longer, causing increasing levels of heat-absorbing gases like carbon dioxide. Our cars and factories are the principal sources of these gases.

3. Rising temperatures cause pronounced atmospheric heating. Hotter air and water along with higher relative humidity altogether stimulate evaporation, cloud formation and eventual precipitation. When there is extreme cold and hot air, a wind system develops, growing into cyclones, hurricanes and tornadoes.

4. Hotter climates cause ice thinning on mountaintops, breaking down of icebergs and floes, melting of the polar ice. The law of displacement explains why our seas are rising, and because all oceans and seas are interconnected, the effect becomes a global one. The first to suffer are those living on low-lying areas. Unfortunately, most cities and town are found on lowlands, near seaports and along major rivers. Thus the next exodus will be ecologically caused. We can call it mass eco-migration. A very disruptive kind of resettlement is needed, dwarfing the kinds of settlement during the era of colonization and conquest. Today’s planners are revolutionizing the concept and design of human habitation that would be decongested and environmentally conserving.

5. There will be a major shift in farming systems where new frontiers will be opened, while others will be abandoned. Adaptation strategies of crops and animals, review of land use policies and programs are back on the drawing boards. Again, environmental conservation will receive special attention.

6. Wildlife migration patterns, niches and distribution, will be greatly affected as their natural habitats are destroyed or modified by changing climate. All living things, without exception, are affected by the man-induced phenomenon of global warming.
