The NASA Goddard Institute for Space Studies (GISS), which is under the direction of Dr. James Hansen, conducts basic research in space and earth sciences. A recent publication by Dr. Hansen and Mki. Sato, entitled Trends of Measured Climate Forcing Agents, found (in part) that a "remarkable deceleration in the growth rate of GHG climate forcing occurred in the past 20 years." The report explains why they believe this is the case and how similar actions, if continued, will keep greenhouse gases from increasing. The site includes a downloadable Adobe Acrobat (.pdf) file of the report and a link to an online science brief.
