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) below the 1981-2010 average …

Baked Alaska: Climate Change in the Arctic

The NOAA releases its latest Arctic Report Card

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, a phenomenon scientists call …

Walruses Forced Onshore Due to Shrinking Sea Ice

35,000 Walruses are forced ashore because there is no 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 fact, for six of …

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

Shrinking ice in the Arctic

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 back the start of …

Melting Arctic Sea Ice Causing More Warming Than Expected

Using satellite data researchers find effect of melting Arctic sea ice has greater impact on global 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 surface reflects back into …
