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…
Equilibrium Climate Sensitivity is the measure of how much the planet will warm in response to a given amount of Greenhouse gas pollution. It is the most important number in climate change science, and past estimates of increased warming may have been too low. Production: Peter Sinclair / Yale Climate Connections Year: 2018 Speakers: Patrick…
Studies point to cognitive impairments at carbon dioxide levels believed possible by the end of this century, additional observation informed models tend to project higher warming scenarios, further research points to the possibility of self-reinforcing feedbacks in the climate system – again affecting the outcome of current unmitigated releases of heat-trapping gases to Earth’s atmosphere.…

The climate change simulations that best capture current planetary conditions are also the ones that predict the most dire levels of human-driven warming, according to a statistical study released in the journal Nature Wednesday. https://www.washingtonpost.com/news/energy-environment/wp/2017/12/06/the-most-accurate-climate-change-models-predict-the-most-alarming-consequences-study-claims Greater future global warming inferred from Earth’s recent energy budget https://www.nature.com/articles/nature24672 Greater future global warming inferred from Earth’s recent energy…
Bruno Tremblay from McGill University speaks about projections for future sea ice extent. This video is part of a panel presentation published by Earth Institute November 2017, with already improved sound quality (reduced humming sound).

This NASA visualization is based on the latest IPCC report, and uses the business as usual scenario, where carbon dioxide concentrations rise to 936 parts per million—more than double today’s levels of 400 parts per million—by the year 2100. Temperature anomalies are estimated to be close to 4°C in the Arctic. https://svs.gsfc.nasa.gov/cgi-bin/details.cgi?aid=11453
Study: There has been a clear decline in the volume of oxygen in Earth’s atmosphere over the past 20 years. A recently proposed model predicts a non-linear decay, which would result in an increasingly rapid fall-off in atmospheric oxygen concentration, with potentially devastating consequences for human health. We predict that humans may continue to survive…
This video with scope on permafrost melting, highlights some of the new developments of our understandings, of what happens in the Arctic due to global warming. The Woods Hole Research Center (WHRC), at the University of Alaska Fairbanks May 11, 2017. Professor of Geophysics Vladimir Romanovsky discusses the impact of Arctic permafrost thaw.

Past sea level rise is not captured by models yet, in particular the response from ice sheets in Antarctica due to global warming. Projections therefore can often be regarded to potentially underestimate future sea level rise. For example, Overpeck et al. (2006), and Hansen (2007) suggest possibilities which could eventually lead to a nonlinear response…
Recently a mysterious Siberian crater has been discovered, which subsequently raised questions about the circumstances surrounding the crater formation. Theories include Pingo formation and connections to the thawing of permafrost (ClimateState reported). Robert Scribbler, summed it up: One theory on the feature is that it might be a pingo — a melting of a permafrost water pocket…
