Warming Temperatures Alter Arctic Lake Biochemistry
Rapidly rising surface temperatures in the Arctic have unleashed a cascade of changes to the region's ecology and geochemistry. Now Canadian, American, and European scientists have found that in high Arctic lakes, climate change may cause population growth in bacteria that reduce sulfate compounds (Environ. Sci. Technol., DOI: 10.1021/es101991p). This bacterial boom could lead to higher levels of methylmercury, a bioavailable form . . .
