Scientists have been debating whether or not mantle plume heat contributes to western Antarctica’s instability. Some recent studies provided evidence this might be the case, but even this study’s authors were skeptical. “I thought it was crazy,” Hélène Seroussi, the study’s co-author and scientist at NASA’s Jet Propulsion Laboratory, said in a release. “I didn’t see how we could have that amount of heat and still have ice on top of it,” Seroussi said in a statement. NASA says Seroussi’s study provides more evidence of geothermal activity underneath a portion of the world’s largest ice sheet.
Because Agung is located near the equator, a major eruption with ash flying up into the stratosphere would have short-term climatic impacts that could last a few years. Agung last erupted in 1963 with an explosivity index of VEI 5, sending a plume of ash some 25 km into the atmosphere before leading to a cooling of 0.5°C. The eruption of Pinatubo in the Philippines in 1991 led to a global cooling of 0.5°C.
A survey of the region of the West Antarctic Rift System has revealed 91 new volcanoes hidden within the ice. The new volcanoes are on top of the 47 whose peaks are above the ice and were already known about. The volcanoes range in height from 100m to a towering 3,850m tall. Geologists say the range has similarities to east Africa’s volcanic ridge, which was previously thought to have the densest concentration of volcanoes in the world.
On the HadCRUT4 data, there has been no global warming for close to eight years, since March 2014. That period can be expected to lengthen once the HadCRUT data are updated – the “University” of East Anglia is slower at maintaining the data these days than it used to be.
Michael Shellenberger: A major new staff report from the New York Federal Reserve Bank throws cold water on the over-heated rhetoric coming from activist investors, bankers, and politicians. “How Bad Are Weather Disasters for Banks?” asks the title of the report by three economists. “Not very,” they answer in the first sentence of the abstract.
The reason is because “weather disasters over the last quarter century had insignificant or small effects on U.S. banks’ performance.” The study looked at FEMA-level disasters between 1995 and 2018, at county-level property damage estimates, and the impact on banking revenue.
UK Independent: "Your home, sometime in the next decade. You click the heating on and receive an app notification telling you how much of your carbon allowance you’ve used today. Outside in the drive, your car’s fuel is linked to the same account. In the fridge, the New Zealand lamb you’ve bought has cost not just pounds and pence but a chunk of this monthly emissions budget too. Welcome to the world of personal carbon allowances – a concept that is increasingly gaining traction among experts as a possible response to the climate crisis. Each month, it would see every person or household in the country given a limited emissions quota to spend on heating, energy, travel, food and possibly consumer goods. Those who wish to expend more could buy top-ups. Those who require less would be able to sell their left-overs back to the ‘grid’." ... Now, in the wake of Cop26, many feel the concept – radical, perhaps, but demonstrably do-able – has never been riper for consideration. So, could this be our future? ... “By establishing an equal monthly budget for everyone, you create a sense of a shared effort to address a shared problem,” says Fawcett.
