Arctic Warming Faster Than Any Place on Earth, Space Imagery Shows
Climate Trends in the Arctic as Observed from Space from Wiley Research News on Vimeo.
The Arctic is a region in the midst of a historical transformation and satellite imagery is allowing scientists to observe these changes unfolding, explains WIREs Climate Change.
Using imagery dating from 1979 to the present, the research records the retreat of snow and ice across the region as more heat is absorbed by the Earth’s surface. This is resulting in ice losses across the Northern Hemisphere, from ice sheets in Greenland to permafrost in parts of North America and Eurasia.
Such a rapid rate of decline indicates that the perennial ice, which is the mainstay of the Arctic ice cover and has been known to have existed for at least 1450 years, is in the process of disappearing.
“The Arctic region has been warming faster than anywhere else in the globe from 1981 to 2012,” said Dr. Josefino Comiso from Cryospheric Sciences Laboratory, NASA Goddard Space Flight Center. “Such warming is manifested strongly in all components of the cryosphere in the Northern Hemisphere.”
