Ananova: Car Exhausts "May Slow Global Warming"

A climate expert says global warming could be balanced out by the cooling effect of car exhausts. He says aerosols pumped out by vehicles can lead to the formation of rain droplets in clouds which, in turn, has a cooling effect. Computer climate models which predict global warming may not have taken this effect into account.

Ran Ramanathan, of the Scripps Institution of Oceanography in California, says aerosol output has increased by about a third since 1980. The Times reports he has calculated that the cloud-seeding effect of aerosols could lower temperatures locally by up to 2.5C.

Aerosols are also produced by industrial processes and naturally by volcanoes but do have some negative health and environmental effects. Ramanathan said: "There is a possibility that it might add more impact or virtually balance all the impact of greenhouse warming."
