“Unimaginable Amounts of Water”: Human-Made Global Heating in Danger of “Uncorking” Massive Antarctic Glaciers, causing Sea Level Rise

Juan Cole

Ann Arbor (Informed Comment) – A new article in Geophysical Research Letters found that four times as much of the Antarctic ices shelves would melt under a scenario where we heat the earth by 7.2 degrees F. (4 degrees C.) as opposed to the current Paris Climate Treaty goals of 1.5 degrees C. or at […]

Juan Cole

Ann Arbor (Informed Comment) – In a scientific shocker, the National Oceanic and Atmospheric Administration has found that despite the slowdown in carbon dioxide emissions in 2020 because of the pandemic, the concentration of CO2 in the atmosphere rose to a global average of 412.5 parts per million (ppm) from 410 in 2019. At the […]
