Arctic Sea Ice Extent 2nd lowest on Record for the Date

Another “warm” and slow freeze season in the #Arctic. Sea ice extent is the 2nd lowest on record for the date (2016 – lowest) & 1.9 million km^2 below the 1980s average… https://twitter.com/ZLabe/status/932663163476045825

What’s Happening to the Greenland Ice Sheet? (October 2017)

The Greenland ice sheet is one of the largest contributors to global sea level rise, and if completely melted, could add ~7 meters to sea level. In recent years, the imbalance of the ice sheet has increased with warmer atmospheric conditions. In this talk, Visiting Assistant Professor Samiah Moustafa describes the field’s current knowledge on…

Largest Glacier East Antarctic may add to Sea Level Rise (Totten Glacier)

Totten Glacier, the largest glacier in East Antarctica, is being melted from below by warm water that reaches the ice when winds over the ocean are strong — a cause for concern because the glacier holds more than 11 feet of sea level rise and acts as a plug that helps lock in the ice…

Antarctic Volcanoes Waking up?

Nearly 100 Volcanoes Discovered Beneath Antarctica’s Ice http://blogs.discovermagazine.com/d-brief/2017/08/14/volcanoes-under-antarctica A new volcanic province: an inventory of subglacial volcanoes in West Antarctica http://www.geos.ed.ac.uk/homes/rbingha2/48_2017_Vries.pdf Scientists discover 91 volcanoes below Antarctic ice sheet This is in addition to 47 already known about and eruption would melt more ice in region affected by climate change https://www.theguardian.com/world/2017/aug/12/scientists-discover-91-volcanos-antarctica How a melting ice…

NASA Laser Reveals Miles of Greenland Ice Loss

What if you could measure a glacier in such detail that you could visualize its surface in 3D? And what if you could compare that view with data from one, two, even 20 years ago? NASA airborne campaigns like Operation IceBridge have been measuring Greenland and Antarctica’s glaciers and ice sheets with a range of…

Vanishing Arctic Ice and Amplification

While heat waves and more intense storms have been directly linked to a warming Earth, new research is exploring possible impacts of an Arctic that is warming at twice the pace of the rise in global temperatures. Jennifer Francis, Rutgers University, discusses new research and efforts to understand this controversial aspect of climate change in…

Like Champagne opened, methane explosions resulted in Ocean craters

Like ‘champagne bottles being opened’: Scientists document an ancient Arctic methane explosion What could possibly go wrong, ignoring climate change, the warnings or clues from what science tells us, even if we were just creating a better world with clean energy, and millions of new jobs? One thing which could go very wrong, are based…

NASA Discovers a New Mode of Ice Loss in Greenland (Solitary Wave)

A new NASA study finds that during Greenland’s hottest summers on record, 2010 and 2012, the ice in Rink Glacier on the island’s west coast didn’t just melt faster than usual, it slid through the glacier’s interior in a gigantic wave, like a warmed freezer pop sliding out of its plastic casing. https://www.jpl.nasa.gov/news/news.php?feature=6857 “You could…
