Guest blogger Lisa Moore, Ph.D., is a scientist in the Climate and Air Program.
There's always something new in climate change research. This week, scientists described the risks of geo-engineering, proposed an efficient way to reduce Arctic climate change, and discussed options for decreasing deforestation in developing countries.

Using geo-engineering to reduce the amount of sunlight reaching the Earth's surface is extremely dangerous. A large, rapid "warming rebound" could result if the technology fails or is stopped, especially if there are no parallel efforts to reduce greenhouse gas emissions. (For more on geo-engineering, see this earlier post.)

Most of the black carbon (soot) that is causing rapid warming in the Arctic comes from Europe, so reducing black carbon emissions in Europe would be a fast and efficient way to slow Arctic climate change.

This special issue reports the results of a workshop in which participants discussed policy options for decreasing greenhouse gas emissions from deforestation in developing countries. More information is available on this website.
