Hiawatha Crater: Bracketing the Age

Guest “Don’t mention the YDIH… (wink, wink, nudge, nudge)” by David Middleton The recent discovery of a large, probably young, impact crater beneath the edge of the Greenland Ice Sheet…

Greenland’s 2021 spring: more snow, less melt

Surface melt and total melt-day area for the Greenland Ice Sheet at the end of the 2021 spring season was below the 1981 to 2010 average. Snowfall and rain (minus…

Chasing cosmic particles with radio antennas in Greenland’s ice

“Detecting radio signals from high-energy neutrinos is a very promising way of significantly increasing the energy range we can access, and thus opening this new window to the cosmos even…

The rocky road to accurate sea-level predictions

“As we said, choosing the wrong equations for the under-ice landscape can have the same effect on the contribution to sea-level rise as a warming of several degrees”, Åkesson says.

Greatest Single Day Gains In Greeenland Ice Happening Now.

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…

Lakes on Greenland Ice Sheet can drain huge amounts of water, even in winter

Using satellite data to ‘see in the dark’, researchers have shown for the first time that lakes on the Greenland Ice Sheet drain during winter, a finding with implications for…

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…

Greenland melting likely increased by bacteria in sediment

Bacteria are likely triggering greater melting on the Greenland ice sheet, possibly increasing the island’s contribution to sea-level rise, according to Rutgers scientists.

Newly Discovered Greenland Plume Drives Thermal Activities in the Arctic

A team of researchers understands more about the melting of the Greenland ice sheet. They discovered a flow of hot rocks, known as a mantle plume, rising from the core-mantle…

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…

Possible 1,000-kilometer-long river running deep below Greenland’s ice sheet

Computational models suggest that melting water originating in the deep interior of Greenland could flow the entire length of a subglacial valley and exit at Petermann Fjord, along the northern…

Greenland and the 1950s Climate Consensus

Glaciers around the world reached their greatest size in four thousand years by 1850. Then abruptly the world began to warm. Arctic sea ice lost 40% of its thickness by…

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…

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…

Graphing The Icy Reality

Guest Post by Willis Eschenbach Today I saw some scary headlines. I post them up along with snippets of the stories. First, from the BBC: Greenland and Antarctica ice loss…

Greenland Ice Core CO2 Concentrations Deserve Reconsideration

Guest post by Renee Hannon IntroductionIce cores datasets are important tools when reconstructing Earth’s paleoclimate. Antarctic ice core data are routinely used as proxies for past CO2 concentrations. This is…

Greenland ice losses rising faster than expected

University of Leeds Greenland is losing ice seven times faster than in the 1990s and is tracking the Intergovernmental Panel on Climate Change’s high-end climate warming scenario, which would see…

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’s ‘Record Temperature’ denied – the data was wrong

From the “But, but, wait! Our algorithms can adjust for that!” department comes this tale of alarmist woe. Greenland’s all-time record temperature wasn’t a record at all, and it never…

Greenland Endures

Inconvenient: NASA says a Greenland glacier did an about-face – growing again

“…scientists were so shocked to find the change.” From NASA JPL: Cold Water Currently Slowing Fastest Thinning Greenland Glacier NASA research shows that Jakobshavn Glacier, which has been Greenland’s fastest-flowing…

Migrating snowline plays outsized role in setting pace of Greenland ice melt

Patches of snow and bare ice near the edge of the snowline provide an illustration of the difference in reflectivity between the two surfaces. Credit Clément Miège PROVIDENCE, R.I. [Brown…
