Shale Oil to Hudson Bay and on to Europe??|
October 27, 2013 | E & E Publishing
E & E Publishing has a new article titled: Moving shale oil across melting tundra: huge and potentially risky business. It concerns a proof-of-concept transport of oil by rail from wells in the Bakken Shale and Alberta Oil sands to a Hudson Bay port for shipment to Europe. This is another alternative for a failing Keystone XL pipeline effort.
Potential 21st Century Temperature, Precipitation Changes|
October 19, 2013 | NASA
“Models used by the IPCC estimate global temperature and precipitation patterns will change throughout the 21st century given current rising greenhouse gas levels. This video depicts a scenario in which carbon dioxide concentrations reach 670 parts per million by 2100, up from around 400 ppm today.” Quoted from the NASA video release.
Enormous Ice Sheets Scoured the Arctic Ocean Floor|
October 11, 2013 | Alfred Wegener Institute
“We knew of such scour marks from places like the Antarctic and Greenland. They arise when large ice sheets become grounded on the ocean floor and then scrape over the ground like a plane with dozens of blades as they flow. The remarkable feature of our new map is that it indicates very accurately right off that there were four or more generations of ice masses, which in the past 800,000 years moved from the East Siberian Sea in a north-easterly direction far into the deep Artic Ocean.” Quoted from the Alfred Wegener Institute press release.
Rapid Ocean Acidification in the Arctic|
September 17, 2013 | USGS
“Acidification of the Arctic Ocean is occurring faster than projected. The increase in rate is being blamed on rapidly melting sea ice, a process that may have important consequences for health of the Arctic ecosystem.” Quoted from the USGS Newsroom.
Climate Change and Extreme Weather|
September 9, 2013 | National Geographic
A National Geographic article titled: Scientists Weigh Climate Change Role in 2012 Weather explores the possibility that human-induced climate change might have contributed to Hurricane Sandy, drought in the Midwest or melting arctic ice.
Canyon Beneath Greenland Ice is 460 Miles Long|
September 1, 2013 | NASA
“Hidden for all of human history, a 460 mile long canyon has been discovered below Greenland’s ice sheet. Using radar data from NASA’s Operation IceBridge and other airborne campaigns, scientists led by a team from the University of Bristol found the canyon runs from near the center of the island northward to the fjord of the Petermann Glacier.” Quoted from the NASA video release.
Plumbing Under the Greenland Ice Sheet|
August 27, 2013 | National Science Foundation
“Scientists’ understanding of how Greenland Ice Sheet melt water travels in passages along the bedrock below fails to account for some key processes. This, in turn may be affecting their assessment of how ice sheets respond to climate change.” Quoted from the National Science Foundation press release.
$60T Methane Time Bomb in the Arctic|
July 25, 2013 | Erasmus University Rotterdam
“Economic modelling shows that the methane emissions caused by shrinking sea ice from just one area of the Arctic could come with a global price tag of 60 trillion dollars – the size of the world economy in 2012.” Quoted from the Erasmus University Rotterdam press release.

The Permafrost Timebomb?|
June 13, 2013 | NASA
Over hundreds of thousands of years the Arctic permafrost has accumulated an enormous store of organic carbon. As it thaws from climate change the plant debris will decay and carbon dioxide and methane will be release into the atmosphere. Permafrost contains at least 4x more carbon than fossil fuel burning has produced since 1850.

Northern Hemisphere Losing Its Last Dry-Snow Region|
May 24, 2013 | Cooperative Institute for Research in Environmental Sciences
“Last July, something unprecedented in the 34-year satellite record happened: 98 percent of the Greenland Ice Sheet’s surface melted, compared to roughly 50 percent during an average summer.” Quoted from the CIRES press release.
No Keystone XL? Send Tankers Through the Arctic|
