Despite warming, the Greatest single day gains in Greeenland ice and its SMB (surface mass balance) is happening the past days. Ice gain/loss in Greenland is function of the location…

Greenland becoming darker, warmer as its snow ages and changes shape
A weather pattern that pushes snowfall away from parts of Greenland’s ice sheet is causing the continent to become darker and warmer, according to Dartmouth research published in Geophysical Research…
The anatomy of past abrupt warmings recorded in Greenland ice
Data availability and temporal resolution make it challenging to unravel the anatomy (duration and temporal phasing) of the Last Glacial abrupt climate changes. Here, we address these limitations by investigating…
Its a Bit more Complicated
The plant matter stuff reported in PNAS is obviously true. So Greenland did mostly melt about 1 mya; otherwise those plants could not have existed there then, however briefly. But…
Greenland Ice Mass Loss Below Average In 2020
What is evident is that there has been no acceleration in melt since the start of records in 2002. This runs counter to the alarmist message commonly perpetuated, for instance…
Newly discovered Greenland (mantle) plume drives thermal activities in the Arctic
The research team discovered that the Greenland plume rose from the core-mantle boundary to the mantle transition zone beneath Greenland. The plume also has two branches in the lower mantle…
Greenland Ice Sheet Doomed… Again
Guest “geological perspective” by David Middleton CRYOSPHERE RESEARCH UPDATEUnprecedented ice loss is predicted for Greenland Ice Sheet30 Sep 2020 Over the next eighty years global warming is set to melt…
Guardian Scratching for Climate Tipping Points
According to The Guardian, the melting of Greenland, which could take centuries, could trigger several meters sea level rise and a cascade of other urgent tipping points. But rising sea…
Claim: Sea level rise from ice sheets track worst-case climate change scenario
Ice sheets in Greenland and Antarctica whose melting rates are rapidly increasing have raised the global sea level by 1.8cm since the 1990s, and are matching the Intergovernmental Panel on…
Claim: Warming Greenland ice sheet passes point of no return
Nearly 40 years of satellite data from Greenland shows that glaciers on the island have shrunk so much that even if global warming were to stop today, the ice sheet…

Why the recently discovered Hiawatha Crater in Greenland is not the Younger Dryas impact.

Deep Purple — future biological darkening of the Greenland Ice Sheet
Purple algae are making the western Greenland Ice Sheet melt faster, as the algae darken the ice surface and make it absorb more sunlight GFZ GeoForschungsZentrum Potsdam, Helmholtz Centre The…
Greenland ice melting four times faster than in 2003, study finds
Public Release: 21-Jan-2019 Southwest part of the island could be major contributor to sea level rise Ohio State University COLUMBUS, Ohio – Greenland is melting faster than scientists previously thought–and…
Melting ice sheets release tons of methane into the atmosphere, study finds

“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…
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…
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…
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…
Study: Greenland Ice Sheet was smaller 3000-5000 years ago than today
From the University of Buffalo Clues in the Arctic fossil record suggest that 3-5,000 years ago, the ice sheet was the smallest it has been in the past 10,000 years…
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…
Surprise: Greenland ice gets a melt assist from Earth's hot mantle below
From the Helmholtz Association Greenland ice is melting — also from below Heat flow from the mantle contributes to the ice melt The Greenland ice sheet is melting from below,…
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…
Great News from Greenland
Guest essay by Dr. Patrick J. Michaels I recently returned from a trip to Greenland’s Jokabshavn Glacier, which discharges more ice than any other in the Northern Hemisphere. Our route…
