CarbonBrief recently published a guest article by Robert M. DeConto, Pamela Pearson, and David Pollard, called Overshooting 2C risks rapid and unstoppable sea level rise from Antarctica. Here is now a text-to-speech conversation for people who like to listen to it. Visit Overshooting 2C risks rapid and unstoppable sea level rise from Antarctica to follow…
The 2021 published study Non-Monotonic Response of the Climate System to Abrupt CO2 Forcing (10.1029/2020GL090861) involves research from the Department of Applied Physics and Applied Mathematics, NASA Goddard Institute for Space Studies, Center for Climate System Research, and the Lamont-Doherty Earth Observatory. The study key points are: We examine the response of the climate system…
An international team of scientists, from Texas A&M University, the University of Southampton and the Swiss University ETH Zürich, led by the University of St Andrews, published their findings in the study, Atmospheric CO2 over the Past 66 Million Years from Marine Archives. The international team pulled together data collected over the last 15 years using high-tech laboratory techniques. The combined data spans the…
A NASA / JPL study published in the journal Environmental Science and Technology found that the potent greenhouse gas methane is leaking from the Permian Basin oilfield, located in Texas and New Mexico. Sensor-equipped aircraft probed the atmosphere over the region for a month, and identified 123 hot spots – leaking 55 tons (50 metric…
A new study be the University of Manitoba, finds that for every degree of global warming, the open water period in the Arctic will increase by roughly one month. The study, Arctic open-water periods are projected to lengthen dramatically by 2100 – published in the Nature journal Communications Earth & Environment, notes: The shrinking of Arctic-wide…
A new study suggests that the East Antarctica Ice Sheet in the Wilkes Basin may have completely disappeared around 400,000 years ago. Currently the Wilkes Basin is only hold back by the Cook, Mertz, and the Ninnis glacier – the Cook Glacier shelf has already collapsed. There is also the Totten Glacier farther to the…

The amount of ice circling Antarctica is suddenly plunging from a record high to record lows, baffling scientists. A new NASA study by sea ice expert Claire L. Parkinson reveals recent trends in Antarctica’s sea ice extent. CREDITS A 40-y record reveals gradual Antarctic sea ice increases followed by decreases at rates far exceeding the…
Scientists at the University of Alaska Fairbanks’ Geophysical Institute used data from NASA’s Operation IceBridge to develop a more accurate model of how the Greenland Ice Sheet might respond to climate change in the future, finding that it could generate more sea level rise than previously thought. Watch a narrated NASA model visualization In the…
