Thwaites glacier: Significant geothermal heat beneath the ice stream

Nevertheless, the heat flow could be a crucial factor that needs to be considered when it comes to the future of Thwaites Glacier. According to Gohl: “Large amounts of geothermal…

Pine Island Glacier’s ice shelf is ripping apart, speeding up key Antarctic glacier

“The recent changes in speed are not due to melt-driven thinning; instead they’re due to the loss of the outer part of the ice shelf,” Joughin said. “The glacier’s speedup…

Claim: Antarctica is headed for a climate tipping point by 2060, with catastrophic melting if carbon emissions aren’t cut quickly

Some other researchers suggest that ice cliffs in Antarctica might not collapse as quickly as those in Greenland. But given their size and current rates of warming – far faster…

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…

Mass balance of the Antarctic ice sheet 1992–2016: reconciling results from GRACE gravimetry with ICESat, ERS1/2 and Envisat altimetry

During 1992–2016, the AIS changed from a positive mass balance of over 100 Gt a−1, which was reducing sea-level rise by 0.3 mm a−1, to a state of balance close…

Claim: Evidence of Antarctic glacier’s tipping point confirmed for first time

He added: “The possibility of Pine Island Glacier entering an unstable retreat has been raised before but this is the first time that this possibility is rigorously established and quantified.

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…

In the deep sea, the last ice age is not yet over

Cruise leader Gerhard Bohrmann summarizes: “At the end of the SUGAR-3 programme, the drilling campaign with MeBo200 in the Black Sea showed us once again very clearly how quickly the…

PAGES 12K: The Ice Age Goeth

Guest “damning with faint praise” by David Middleton Kaufman, Mckay, Routson, et al., 2020 In my previous post, I noted a “funny pattern” in the latest Holocene climate reconstruction (Kaufman,…

NASA’s ICESat-2 satellite reveals shape, depth of Antarctic ice shelf fractures

PENN STATE Research News When a block of ice the size of Houston, Texas, broke off from East Antarctica’s Amery Ice Shelf in 2019, scientists had anticipated the calving event,…

Freshwater outflow from Beaufort Sea could alter global climate patterns

The Beaufort Sea, the Arctic Ocean’s largest freshwater reservoir, has increased its freshwater content by 40 percent over the last two decades, putting global climate patterns at risk. A rapid…

Global Ice Story: What they don’t tell you

The Arctic includes the Arctic Ocean, Greenland, Iceland, and part of Siberia and northern Alaska. Because of the absence of any land mass in the Arctic Ocean, most of area…

The CO2 Kink; Firn to Ice Transition

Guest Post by Renee Hannon Introduction This post examines CO2 data collected in Antarctic firn and its journey as firn transitions to ice where CO2 is eventually trapped in bubbles.…

Researchers discover a new tool for reconstructing ancient sea ice

In a study published in Nature Communications, the researchers show that an organic molecule often found in high-latitude ocean sediments, known as tetra-unsaturated alkenone (C37:4), is produced by one or…

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…

Rivers melt Arctic ice, warming air and ocean

A new study shows that increased heat from Arctic rivers is melting sea ice in the Arctic Ocean and warming the atmosphere.

Perhaps the dumbest article title ever: “The Arctic hasn’t been this warm for 3 million years”… AEUHHH???

Guest “you can’t fix stupid” by David Middleton The sad thing is that this was apparently written by two geoscience professors. The Arctic hasn’t been this warm for 3 million…

“Where’s the sea ice?” Right where it’s been for most of the Holocene.

Where’s the sea ice? 3 reasons the Arctic freeze is unseasonably late and why it matters

I’ve watched the region’s transformations since the 1980s as an Arctic climate scientist and, since 2008, as director of the National Snow and Ice Data Center. I can tell you,…

On noes! Antarctic sea ice may not cap carbon emissions as much as previously thought
