Actual Expert tells audience, We won’t have an Ice Age again!

Hans Joachim Schellnhuber (Potsdam Institute for Climate Impact Research), speaks October 2018 at the 50th Anniversary Summit of the Club of Rome, Aurelio Peccei Lecture, in Rome. The talk is titled, “Climate, Complexity, Conversion”. The talk briefly discusses the 2018 landmark study, “Trajectories of the Earth System in the Anthropocene” https://www.pnas.org/content/115/33/8252 , delves into societies…

NASA’s 2018 Permafrost Special “All Hell Breaks Lose”

This week, #NASAExplorers head back in time…by going underground. In the Arctic, a frozen layer of soil – permafrost – trapped dead plants and animals for thousands of years. As the climate warms, that soil is beginning to thaw, releasing carbon dioxide and methane. Release via https://www.youtube.com/watch?v=y7ZbghndiwQ

Permafrost Melt Fires may Accelerate Greenland Melt

Dr. Nikolaos Evangeliou on climate change and wildfires (Oslo, August 2018). Evangeliou works at NILU – Norwegian Institute for Air Research http://nilu.no “If larger fires would burn, they would actually have a substantial impact on melting,” Stohl said. And, there’s a greater chance of such fires, if more of Greenland’s permafrost melts and exposes peat…

Is THIS Graph the only one needed to act on Global Warming?

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.…

Experts Discuss Recent Heat Waves and Atmospheric Changes

The impacts of global warming are now ‘playing out in real-time’. Mike Mann (Penn State), Jennifer Francis (Rutgers), and Noah Diffenbaugh (Stanford), discuss the recent heat waves around the globe, and how it connects with the jet stream pattern, moderated by Markeya Thomas of Climate Signals.

The 5 Big Climate Unknowns

Climate unknowns include the rate of sea level rise, ozone loss, how the Gulf Stream will react and what it possibly means, the Earth’s response, and the potential for extra methane release from methane clathrates, stored at continental margins. There are many more climate unknowns, for example elaborated in this article https://thinkprogress.org/what-are-the-unknown-unknowns-of-global-warming-1438d934bdee Climate Change Interview…
