BOULDER, Colo., June 12 (UPI) -- U.S. scientists say the rate of climate warming over northern Alaska, Canada, and Russia could more than triple during periods of rapid sea ice loss.
The findings of the study led by the National Center for Atmospheric Research raise concerns about the thawing of permafrost, or permanently frozen soil, and the potential consequences for sensitive ecosystems, human infrastructure, and the release of additional greenhouse gases.
