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 (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
Guest Post by Willis Eschenbach Charles the Moderator has been doing a fantastic job of keeping WUWT humming along, and deserves everyone’s thanks. Today he sent me an interesting article…
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…
New research finds possible second impact crater hiding under Greenland ice
WASHINGTON — Scientists have discovered a possible second impact crater buried under more than a mile of ice in northwest Greenland. This follows the finding, announced in November 2018, of…
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
From EurekAlert! Public Release: 3-Jan-2019 Melting ice sheets release tons of methane into the atmosphere, study finds University of Bristol Melting ice sheet release tons of methane into the atmosphere,…
Greenland Is Melting Faster Than Ever
From LiveScience By Stephanie Pappas, Live Science Contributor | December 5, 2018 02:00pm ET Each summer, large rivers emerge on the surface of Greenland, swiftly sending meltwater from the ice…
Greenland Ice Sheet apparently gains mass for the 2nd year in a row
Long-time WUWT reader Dave Burton writes: I’ve seen no official pronouncement from DMI, but here are their graphs for Greenland Ice Sheet (GIS) surface mass balance (SMB), for the 2016-2017…
Woods Hole: Greenland Ice Melt linked to the natural AMO cycle
