Nature Geoscience:n julkaisema uusi tutkimus katsoo epätäydellisessä palamisessa syntyneen hiilipölyn oleva 50%:sti syynä 1,9 C asteen lämpötilan nousuun 1890-2007
Arktisella alueella. Tutkimus tulee NASA Goddard´ilta ja (GISS) ja Columbian yliopistolta.

"Washington, D.C., April 2, 2009 – An article published this week in Nature Geoscience shows that black carbon is responsible for 50 percent, or almost 1°C of the total 1.9°C increased Arctic warming from 1890 to 2007. The paper by Drew Shindell of the NASA Goddard Institute for Space (GISS) and Greg Faluvegi of Columbia University also notes that most of the Arctic warming – 1.48°C of the 1.9°C – occurred from 1976 to 2007. The study is the first to quantify the Arctic’s sensitivity to black carbon emissions from various latitudes, and concludes that the Arctic responds strongly to black carbon emissions from the Northern Hemisphere mid-latitudes, where the emissions and the forcing are greatest"
