The idea that global warming would melt the ice caps and flood coastal cities seems to be mere science fiction. A slight increase in temperature (whether natural or mankind induced ) is not likely to lead to a massive melting of the earth ice caps, as sometimes claimed in the media. Also, sea-level rises over the centuries relate more to warmer and thus expanding oceans, not to melting ice caps.
Contrary to some groups' fear mongering about the threat of diseases, temperature changes are likely to have little effect on the spread of diseases. Experts say that deterioration in public health practices such as rapid urbanization without adequate infrastructure, forced large scale resettlement of people, increased drug resistance, higher mobility through air travel, and lack of insect-control programs have the greatest impact on the spread of vector-borne diseases.
Larger quantities of CO2 in the atmosphere and warmer climates would likely lead to an increase in vegetation. During warm periods in history vegetation flourished, at one point allowing the Vikings to farm in now frozen Greenland. |
