Thawing Russian Arctic Permafrost Leads to Anthrax Outbreak

Seventy-two nomadic herders, including 41 children, living in the Russian Arctic Circle town of Salekhard have been hospitalized since reindeer began dying en masse due to an anthrax outbreak that scientists linked to rising temperatures, which is causing permafrost to thaw.

Landsat Study Reveals Greening Across North America’s Arctic

Analyzing 29 years worth of satellite images (1984-2012), a NASA Goddard Space Flight Center research team found nearly one-third of land cover has been changing to resemble landscapes in warmer ecosystems.

Shrinking sea ice forces Polar Bears into "marathon" swims as population declines

Polar Bears Undertaking Marathon Swims, Populations Declining Rapidly as Sea Ice Disappears

The polar bear population in the Beaufort Sea area have declined 50% or more in the last decade. Nearly 7 in 10 of the 100 bears the researchers monitored swam at least 49 km (30.44 mi) in 2012. That’s up 25% from 2007.

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.

Researchers Flock to the Arctic as CO2 Surpasses 400PPM

New Arctic Ocean data adds to evidence linking rising CO2 levels to climate warming, which is occurring faster than it has since long before the Age of the Dinosaurs. A team of 40 researchers is gathering Arctic Ocean data before the region as we know it ceases to exist as the global average concentration of atmospheric CO2 surpassed 400 ppm.

Microbes Could Quickly Unlock Huge Carbon Stores in Arctic Permafrost

A first-of-a-kind study indicates microbial action on thawing Arctic permafrost can result in rapid increases in atmospheric CO2. Extending across northern Eurasia and Alaska, the equivalent of more than twice as much CO2 is stored in Arctic permafrost as is present in the atmosphere, highlighting the risk and threats posed by a warming climate.

Shell abandons Arctic because of market forces, not environmental epiphany

Why Shell Abandoned the Arctic: A Primer on Market Forces for Activists

While the laudable efforts of activists have been given credit for ending Arctic drilling, environmentalists could benefit from a better understanding of the dynamics at play. Attributing Shell’s decision to cease its drilling operations in the Arctic to environmental protest is an undeniably compelling narrative. If only a handful of passionate kayaktavists could stop Shell from drilling in the Arctic. The problem is that it is not true. It…
