Recent published research shows the danger of massive, potentially irreversible, global sea-level rise within the next couple of centuries should temperatures overshoot 2°C. Perhaps most sobering, this loss may become rapid and permanent, with no halt in ice loss even should CO2 concentrations return t pre-industrial levels; and rates approaching 5 cm/year by 2150, and…
We interviewed Eric Rignot, Donald Bren Professor and Chancellor Professor of Earth system science at the University of California, Irvine and Senior Research Scientist for the Radar Science and Engineering Section at NASA’s Jet Propulsion Laboratory. The 6th IPCC Report and Sea Level Rise Chris Machens: Hello Eric, back in 2015 I’ve asked you about…
This data visualization depicts the last 25 years of Antarctic land ice elevation change. Areas in red indicate land ice loss. Watch the NASA visualization Areas in blue are regions that saw land ice elevation gains. The camera starts with a view of the Earth and then flies down to Antarctica, where it pauses to…
Is unavoidable sea level rise an engineering problem, do we have the capabilities for a technological fix? John C. Moore from the Arctic Centre of the University of Lapland presents these ideas in his October 2018 talk, “Stopping the flood – Can we engineer ice sheets and save the homes of a billion people?” Open…

Mass balance of the Antarctic Ice Sheet from 1992 to 2017 – ocean-driven melting has caused rates of ice loss from West Antarctica to increase from 53 ± 29 billion to 159 ± 26 billion tonnes per year; ice-shelf collapse has increased the rate of ice loss from the Antarctic Peninsula from 7 ± 13 billion to 33 ± 16 billion tonnes per…
Presentation by Peter Clark from Rutgers University, Sea-level Rise Over the Next 100 to 10,000 Years in Response to Global Warming: An Update to IPCC AR5 (April 2018).
Past studies of Antarctica’s accelerated glacier retreat focused on regional trends, a new study now finds continental trends of over ten percent of marine terminating glaciers moving inland. Current peak retreat has been documented to be in the ballpark of 25 meters each single year. Read Chris Mooney’s Washington Post article study summary goo.gl/HuxtxL /…
