Black Carbon in Snow and Climate Change
March 5, 2013 | Cooperative Institute for Research in Environmental Science
"Black carbon particles in snow are larger than expected [...] this finding suggests that the warming produced by black carbon in snow could be currently overestimated by as much as 30 percent." Quoted from the CIRES press release.
The Permafrost Timebomb?
June 13, 2013 | NASA
Over hundreds of thousands of years the Arctic permafrost has accumulated an enormous store of organic carbon. As it thaws from climate change the plant debris will decay and carbon dioxide and methane will be release into the atmosphere. Permafrost contains at least 4x more carbon than fossil fuel burning has produced since 1850.
Intentionally Weathering Olivine to Fight Climate Change?
January 23, 2014 | Nature
A Nature article reports how some researchers believe that climate change can be mitigated by crushing olivine-rich rocks and exposing them to weathering - to take advantage of olivine's ability to sequester carbon.
