Human-Produced Aerosols in Many Arctic Clouds Contribute to Climate Warming

Two scientists from Scripps Institute of Oceanography and Brookhaven National Laboratory have measured the impact of a significant anthropogenic source of warming: aerosol concentrations in Arctic clouds. The research is published in the current issue of Nature.

The team used radiometric data to show that increased concentrations of aerosols in the clouds cause the cloud droplets to become smaller and, within clouds of fixed water amounts, more abundant. This process, known as the
