“Terrifying Sea-Level Prediction Now Looks Far Less Likely”… But “marine ice-cliff instability” is “just common sense”

Guest AEUHHH???? by David Middleton A Terrifying Sea-Level Prediction Now Looks Far Less Likely But experts warn that our overall picture of sea-level rise looks far scarier today than it did even five years ago. ROBINSON MEYER JAN 4, 2019 One of the scariest scenarios for near-term, disastrous sea-level rise may be off the table…

A massive crater hides beneath Greenland’s ice

Elevating this from a mention in my previous Newsworthy Items post. From ScienceNews Whether the impact is related to a period of cooling called the Younger Dryas is unknown By Carolyn Gramling 2:00pm, November 14, 2018 There’s something big lurking beneath Greenland’s ice. Using airborne ice-penetrating radar, scientists have discovered a 31-kilometer-wide crater — larger…

Enormous Aquifer Discovered Under Greenland Ice Sheet

From NASA, I had to laugh at this statement: The water in the aquifer has the potential to raise global sea level by 0.016 inches (0.4 mm). That’s assuming it can get out sometime in the distant future. Greenland’s topography under the ice is bowl shaped. =================================== Buried underneath compacted snow and ice in Greenland…

Lakes discovered beneath Greenland ice sheet

From the University of Cambridge The subglacial lakes are the first to be identified in Greenland The study, published in Geophysical Research Letters, discovered two subglacial lakes 800 metres below the Greenland Ice Sheet. The two lakes are each roughly 8-10 km2, and at one point may have been up to three times larger than…

NASA to do summer aerial melt watch for Greenland

NASA Begins Airborne Campaign to Map Greenland Ice Sheet Summer Melt For the first time, a NASA airborne campaign will measure changes in the height of the Greenland Ice Sheet and surrounding Arctic sea ice produced by a single season of summer melt. NASA’s C-130 research aircraft flew from the Wallops Flight Facility in Wallops…

Oh, what a difference a year makes in Greenland melting

ARCTIC SUMMER SNOWSTORM By Joseph D’Aleo CCM Remember a year ago when few days of July ‘warmth’ with strong blocking over Greenland had the media abuzz over some melting? Last July a brief spell of temperatures in the mid 30s had caused some surface slush formation on top of the 1 to 1.5 mile thick…
