er features are particularly sensitive to temperature shifts, and that "scientists suspect the enhanced melting is among the first observable signs of human induced global warming. Some of the effects of global warming are as follows: arctic ocean sea ice shrunk by 6% since 1978, with a 14% loss of thicker year round ice, Greenland ice sheet has thinned by more than a meter a year on its southern and eastern edges since 1993 and 22% of glacial ice volume on the Tien Shan mountains has disappeared in the last 40 years. Worldwatch declared that the Earth's ice cover reflects much of the sun's heat back into space and the loss of much of it would affect the global, raise sea levels, and threaten water supplies. They also stated that the land and water left revealed by the retaining ice would themselves retain heat, creating a feedback loop that would speed up the warming process. The institute pronounced that the world's glaciers, taken as a whole, are now shrinking faster than they are growing. Worldwatch also warns of the outcomes of retaining ice on wildlife. In northern Canada reports of hunger and weight loss among polar bears have been associated with ice cover changes. And in Antarctica, sea loss, rising air temperatures and increased condensation are altering the habitats and the feeding and breeding patterns of seals and penguins. Cornell University ecologists believe that global warming may account for millions of human deaths from disease. David Pimentel a professor of ecology at Cornell stated and assumes that "Most of the increase in disease is due to numerous environmental factors, including infectious microbes, pollution by chemicals and biological wastes and shortages of food and nutrients. Global warming will only make matters worse." Global warming will produce a favorable climate for disease producing organisms and plant pests. Global climate change will result in a net loss of obtainable food, for example the decline in...
