Arctic Sea Ice Loss 
Expected to be Bumpy in the Short Term


Arctic sea ice extent plunged precipitously from 2001 to 2007, then it barely budged between 2007 and 2013. Even in a warming world, researchers can expect such unusual periods of no change—and rapid change—at the world’s northern reaches, according to a new paper. “Human-caused global warming is melting Arctic sea ice over the long term, but the Arctic is a variable place, said Jennifer Kay, a fellow of the Cooperative Institute for Research in Environmental Sciences at the University of Colorado Boulder and co-author of the new analysis in Nature Climate Change. Natural ups and downs … [Read more...]

NSIDC recovers rescued data and reveals sea ice secrets (video)

Garrett Campel

50 years ago, NASA launched Nimbus to study Earth from space. Now, experts at the National Snow and Ice Data Center (part of CIRES), are recovering valuable data and images from old, long-lost film, and expanding their understanding of sea ice in the Arctic and Antarctic. When NASA launched Nimbus-1 50 years ago, the agency’s key goals were to test instruments that could capture images of clouds and other meteorological features. The Nimbus satellites made such excellent observations, NASA eventually handed over key technologies to the National Oceanic and Atmospheric Administration … [Read more...]

Seasonal Arctic summer ice extent still hard to forecast, NSIDC study says

Arctic sea ice

The following is an excerpt from the National Snow & Ice Data Center. Read the entire press release at http://nsidc.org/news/press/2014_seasonalseaice_PR.html. Will next year’s summer Arctic ice extent be high or low? Can ship captains plan on navigating the famed Northwest Passage—a direct shipping route from Europe to Asia across the Arctic Ocean—to save on time and fuel? A new study says year-to-year forecasts of the Arctic’s summer ice extent are not yet reliable. Scientists at the National Snow and Ice Data Center (NSIDC), University College London, University of New Hampshire and … [Read more...]
