Permafrost Threatened by Rapid Retreat of Arctic Sea Ice, NCAR Study Finds
June 10, 2008
BOULDER-The rate of climate warming over northern Alaska, Canada, and
Russia could more than triple during periods of rapid sea ice loss,
according to a new study led by the National Center for Atmospheric
Research (NCAR). The findings 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.
“Our study suggests that, if sea-ice continues to contract rapidly
over the next several years, Arctic land warming and permafrost thaw
are likely to accelerate,” says lead author David Lawrence of NCAR.
