Global Warming
Monday was the hottest day on record. ... They pointed out that during the twentieth century, the earth’s mean temperature increased by approximately one degree Fahrenheit caused by global warming (Global Surface Mean Temperatures). Because the earth is getting warmer and warmer, the world should understand that global warming is a potentially catastrophic problem that can cause sea levels to rise, climatic disruptions, and even famine.
In order to understand the debate over global warming, it is important to understand the scientific concept known as the greenhouse effect. ... However, as the amount of greenhouse gases in the atmosphere increases, so does the amount of the heat they absorb, the result of that is Global Warming. ... Fred Singer, professor of environmental sciences at the University of Virginia, maintains that global warming may have the opposite effect on sea levels of that predicted by forecasters. ... Therefore, as the earth is warming, the sea levels will increase (Pringle). ...
Furthermore, some scientists suggest that global warming may not result in major climatic disruptions. They argue that the computer models that predict scenarios of climatic mayhem due to global warming are flawed and that the computer models makes various assumptions about the atmosphere, the oceans and their complex interaction (Barbour). ... The degree of change depends on the degree of warming (Barbour). ... The greater the increase, the more drastic changes can occur (Global Surface Mean Temperatures). Another factor affecting changes is the fact that a global temperature rise is not evenly distributed. ... Global circulation models (GCM) have shown that warming will be focused on polar and temperate zones. ...
Moreover, many say that global warming may not cause famine. They say that if countries make an effort now to eliminate poverty and famine, it is unlikely that global warming will cause famines in these countries in the future (Barbour). ... Rosenzweig and Martin Parry, researchers studying global warming, expect the rising temperatures to affect agriculture worldwide and predict that massive crop failures in developing countries are due to global warming (Jenkinson). ...
While studying the effects of global warming, the researchers found that although the amount of warming was expected to be highest in the northern latitudes, the effect on crops was likely to be more severe in the southern latitudes.
