The Biggest Infrastructure Project Ever Built in Alaska?|
March 20, 2014 | Anchorage Daily News
The Alaska Senate is debating a large project that would involve a natural gas liquefaction plant on the North Slope coastline, a natural gas pipeline system and a natural gas processing plant. The State might have a stake in the project. Presently, lots of natural gas on the North Slope is being flared because it has no access to market. So much is being flared that it can be seen from space.

Rivers Play Role in Arctic Sea Ice Melt|
March 13, 2014 | NASA
“The heat from warm river waters draining into the Arctic Ocean is contributing to the melting of Arctic sea ice each summer. [...] NASA used satellite data to measure the surface temperature of the waters discharging from a Canadian river into the icy Beaufort Sea during the summer of 2012. They observed a sudden influx of warm river waters into the sea that rapidly warmed the surface layers of the ocean, enhancing the melting of sea ice.”

Why Was It So Cold Last Week?|
January 12, 2014 | Climate.gov
An article on Climate.gov explains why a large mass of dense, extremely cold air flowed over much of the United States last week.
From the article… “Meteorologists have known for years that the pattern of the polar vortex determines how much cold air escapes from the Arctic and makes its way to the U.S. during the winter.”
Steam Fog Streaming from the Great Lakes|
January 9, 2014 | NASA Earth Observatory
“A swirling mass of Arctic air moved south into the continental United States in early January 2014. On January 3, the air mass began breaking off from the polar vortex, a semi-permanent low-pressure system with a center around Canada’s Baffin Island. The frigid air was pushed south into the Great Lakes region by the jet stream, bringing abnormally cold temperatures to many parts of Canada and the central and eastern United States.
When the cold air passed over the relatively warm waters of Lake Michigan and Lake Superior, the contrast in temperatures created a visual spectacle. As cold, dry air moved over the lakes, it mixed with warmer, moister air rising off the lake surfaces, transforming the water vapor into fog—a phenomenon known as steam fog.” Quoted from NASA’s Earth Observatory.
The Polar Vortex|
January 7, 2014 | Los Angeles Times
A moving mass of dense, cold, Arctic air known as a “polar vortex” is bringing severe temperatures and strong winds to much of the United States and as far south as the Gulf of Mexico.

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.
