ANN ARBOR — Just how much Arctic permafrost will thaw in the future and how fast heat-trapping carbon dioxide will be released from those warming soils is a topic of lively debate among climate scientists.

To answer those questions, scientists need to understand the mechanisms that control the conversion of organic soil carbon into carbon dioxide gas. Until now, researchers believed that bacteria were largely responsible. (more…)

Global Warming will Open Unexpected New Shipping Routes in Arctic, UCLA Researchers Find

Shipping lanes through the Arctic Ocean won’t put the Suez and Panama canals out of business anytime soon, but global warming will make these frigid routes much more accessible than ever imagined by melting an unprecedented amount of sea ice during the late summer, new UCLA research shows.

“The development is both exciting from an economic development point of view and worrisome in terms of safety, both for the Arctic environment and for the ships themselves,” said lead researcher Laurence C. Smith, a professor of geography at UCLA. (more…)
