Future climate could be hotter than thought
study By Patricia Reaney
LONDON (Reuters) - Global temperatures in the future could be much hotter than scientists have predicted if new computer models on climate change are correct, researchers said on Wednesday.
Improvements in air quality will lead to a decrease in aerosols, small particles in the atmosphere that act as a brake on the impact of greenhouse gases. As the effect of aerosols lessen, searing temperatures could follow.
"This new way of integrating the aerosol, greenhouse gas and biosphere effects changes the picture from one where climate change most likely is a fairly tolerable thing to one where there is a fairly high risk of change sooner, and to a higher degree," said Professor Meinrat Andreae.
