13th Consecutive Year of Record Low Arctic Sea Ice Winter Maximums

Spanning 14.52 million square kilometers ( 5.61 square miles) as of March 24, 2015’s winter maximum was reached 12 days later than the average from 1981-2010. A late season surge is still possible, the National Snow & Ice Data Center noted, adding that it will post a detailed analysis of Arctic winter sea ice conditions in late April.

Arctic Sea Ice Maximum Reaches Lowest Extent on Record

Preliminary analysis from the National Snow & Ice Data Center (NSIDC) in Boulder, Colorado shows that Arctic sea ice likely reached its seasonal maximum on February 25th. At 5.61 million square miles (14.54 million square kilometers) the expected maximum ice extent is the lowest in the satellite record. The maximum extent for 2015 is 425,000 sq. miles (1.10 sq. kilometers)…

The NOAA releases its latest Arctic Report Card

Baked Alaska: Climate Change in the Arctic

Arctic report card – If there’s been any “pause” in global warming, the Arctic  hasn’t seen it. The latest Arctic Report Card issued from the National Oceanic and Atmospheric Administration (NOAA) shows a continued acceleration of climate change in the region. This latest report shows that Arctic air temperatures continue to rise at more than twice the rate of global temperatures,…

35,000 Walruses are forced ashore because there is no sea ice

Walruses Forced Onshore Due to Shrinking Sea Ice

I am the Walrus This isn’t the first time Walrus have been forced ashore en masse due to their shrinking habitat of sea ice, and undoubtedly not the last. Last week more than 35,000 Walruses “hauled out” along the coast of northwestern Alaska because nearly all the sea ice the animals use to rest on had all but completely melted away. In…

NASA to Study Arctic Sea Ice Loss’s Climate Impact Like Never Before

With temperatures in the Arctic rising twice as fast as elsewhere, ARISE will be the first NASA airborne Arctic field campaign equipped to simultaneously measure the balance of of factors that determine climate warming.

Artic Sea Ice and Albedo: Ice Free Season Growing 5 Days per Decade

Arctic ice autumn freeze-up starting later  – According to new research to be published in the forthcoming issue of Geophysical Research Letters, the ice-free season in the Arctic is growing by five days per decade. Analysis of satellite data by a team of researchers headed by Julienne Stroeve indicate increasing absorption of solar energy in the summer Arctic ocean is pushing…

Using satellite data researchers find effect of melting Arctic sea ice has greater impact on global warming than expected

Melting Arctic Sea Ice Causing More Warming Than Expected

Scientists have long modeled the expected warming due to the decreased albedo effect as melting Arctic sea ice exposes more open ocean. As early as the 1960’s climate researchers have predicted how this phenomenon will amplify global warming. Arctic ice melt, albedo and global warming Albedo is measured as a percentage, in this case the percentage of solar radiation a…
