Scientists alarmed to discover warm water at "vital point" beneath Antarctica's "doomsday glacier" Antarctic Ice Thickness Map

Scientists have found warm water beneath Antarctica's "doomsday glacier," a nickname used because it is one of Antarctica's fastest melting glaciers. While researchers have observed the recession of the Thwaites Glacier for a decade, this marks the first time they detected the presence of warm water – found at a "vital point" beneath the glacier.

A news release on the findings called it an alarming discovery.

"The fact that such warm water was just now recorded by our team along a section of Thwaites grounding zone where we have known the glacier is melting suggests that it may be undergoing an unstoppable retreat that has huge implications for global sea-level rise," David Holland, director of New York University's Environmental Fluid Dynamics Laboratory and NYU Abu Dhabi's Center for Global Sea Level Change, which conducted the research, said in the news release.

Opinion of the Week...

Now that climate change is irrefutable, denialists like Andrew Bolt insist it will be good for us

Even as the fires roar at the gates of power, the Murdoch columnist and others argue climate change is ‘overall, a good thing’

There was a battered paper cartoon pasted to our office cupboard, sometime back in the year 2000. It depicted a landscape of power plants belching smoke, in the foreground of which was a billboard where an enthusiastic woman in a sunhat sipped a margarita through a straw. A speech bubble came from the woman’s lipsticked mouth: “Global warming?” she gushed. “I can’t wait!”

It was supposed to be a joke.

Memory of that cartoon provoked an old, nihilistic laugh to echo in my throat at a confluence of climate events this week, 20 careless years later. Dear world, three months after they began, the Australian fires are not out. Today, ash is raining in our nation’s capital, orange flames stare over the mountains behind Canberra. Scientific consensus, affirmed by Australia’s exhausted fire chiefs, is that the fires are effects of the anthropogenic climate crisis. And yet even as the fires roar at the physical gates of power, on Sunday the conservative columnist Andrew Bolt, of the Murdoch press, published an insistence that climate change is “overall, a good thing”. The only thing missing from this new cartoon is the lipstick.T

Climate Feedback Claim Review...

Studies do not support blog’s claim that volcanic activity is causing melting of West Antarctic glaciers

CLAIM: Volcanoes are melting west Antarctic glaciers, not global warming.

SOURCE: Volcanoes Melting West Antarctic Glaciers, Not Global Warming by Robert W. Felix, Ice Age Now, Jan 9. 2020

VERDICT: Unsupported 

KEY TAKEAWAY: This claim is not supported by the three studies cited in the article. The article misinterprets the implications of one study and explicitly rejects the conclusions of the other two. All three studies, which investigated geothermal conditions beneath portions of the West Antarctic Ice Sheet and the past behavior of the ice, simply aimed to better understand how the ice sheet will respond to continued human-caused climate change.
