Greenland's "Sponge" Affected By Climate Change

Polar research should include Indigenous perspectives
Pat Wongpan explains why polar research must incorporate diverse views, including those of Indigenous peoples and communities affected by climate change.

Pat Wongpan (@southpolecoffee) delivers a KEY priority for the future of polar research, here in @nature.
Fellow polar researchers, take heed. This is beyond overdue and completely necessary.

@twilamoon @goodnesglaciers @theAGU Pat Wongpan (@southpolecoffee) just had an article that outlines one of the key points far better than that tiny Nature Correspondence piece could. Just came up in @NatureCareers this morning, I highly recommend

Nonlinear rise in Greenland runoff in response to post-industrial Arctic warming
Ice-core-derived melt records reveal that atmospheric warming has recently intensified Greenland ice-sheet surface melt and runoff to levels that are exceptional over at least the last 350 years.
Mike MacFerrin, PhD
@ericsteig @ArgurtO @hausfath @nature @NatGeo @themadstone It’s been at least 350 years unequivocally, and likely at least 5000 before that. Hard to argue with direct ice cores. H/t to @highlatitude for the hard evidence.

With Greenland's Extreme Melting, a New Risk Grows: Ice Slabs That Worsen Runoff
More meltwater is now pouring off these hardened surfaces and toward the ocean, a new study finds. That will have an impact on sea level rise.

Expanding ice slabs are increasing Greenland’s contribution to sea level rise
Since 2001, melting and refreezing have created vast ice layers near the surface that could drastically amp up meltwater runoff and sea level rise.
Rapid expansion of Greenland’s low-permeability ice slabs
Observations and regional climate models show that the increasing coverage of ice slabs on the Greenland ice sheet could lead to a global sea-level rise of up to 74 millimetres by 2100.

Greenland’s Growing “Ice Slabs” Intensify Meltwater Runoff into Ocean
Thick, impenetrable ice slabs are expanding rapidly on the interior of Greenland's ice sheet, where the ice is normally porous and able to reabsorb meltwater. These slabs are instead sending meltwater spilling into the ocean, according to a new...
Something strange is happening to Greenland's ice sheet
What should be like a snowcone is becoming more like a popsicle, speeding up the runoff from the melting ice sheet.

So our latest article about Greenland just dropped in @nature this morning. It's been years coming.
@NatGeo has a writeup here by @themadstone. Greenland is rapidly transforming itself from a "snowcone" to a "popsicle," which is bad news for runoff.

Opinion: UC investments are going fossil free. But not exactly for the reasons you may think
Divesting is less a moral imperative than risk-averse stewardship of the university's endowment and pension fund.
Texas Charges Oil Port Protesters Under New Fossil Fuel Protection Law
This could be the first test of a wave of laws enacted in several states in recent years targeting protests over pipelines and other fossil fuel infrastructure.
