Global Climate Change
The most popular story in 2007 focused on a study conducted by NASA scientists that suggested greenhouse-gas warming may raise average summer temperatures in the eastern United States by nearly 10 degrees Fahrenheit by 2080. Meanwhile, the third most popular story was based on an Ohio State University study that showed temperatures in Antarctica during the late 20th century did not climb as had been predicted by many global climate models. Most models predict that both precipitation and temperature will increase over Antarctica with a warming of the planet.
The NASA weather model, one of the models used in the recently issued climate report by the Intergovernmental Panel on Climate Change, showed that extreme summertime surface temperatures developed when carbon dioxide emissions were assumed to increase about 2 percent a year, the business as usual scenario.
