Soot packs a punch on Tibetan Plateau's climate
— 4 Mar 2011 15:48 | EnvironmentIn some cases, soot - the fine, black carbon silt that is released from stoves, cars and manufacturing plants - can pack more of a climatic punch than greenhouse gases, according to…
Scripps oceanography researchers discover Arctic blooms occurring earlier
— 3 Mar 2011 13:50 | EnvironmentWarming temperatures and melting ice in the Arctic may be behind a progressively earlier bloom of a crucial annual marine event, and the shift could hold consequences for the entire…
