GLOBAL WARMING
Opinions about our future climate are widely debated by scientists. While some data suggest that a return of glacial conditions is likely in only a few thousand years, a growing awareness of global climatic change driven by deforestation and greenhouse warming by humans burning of fossil fuels has alarmed the scientific community. Scientist believe that the planet is headed toward much warmer climates, which will raise sea levels, change rainfall patterns and growing seasons. Whether these man-made effects will dominate over natural trends is a matter of great scientific and political interest.
