Extinction Events in Earth History and Today

Flood Basalts and Mass Extinctions – refine ancient hyperthermals as analogs for anthropogenic climate change.  Oceanic Anoxic Event (OAE) and mass extinctions are considered to be hyperthermals – usually associated with flood basalt eruptions.[2] Phases of rapid global warming, known collectively as hyperthermals.[1]  Flood basalts are a subset of large igneous provinces (LIPs), the terms flood basalt…

The Current State of Arctic PERMAFROST THAW

Soil layers of permafrost that scientists expected to remain frozen for at least 70 more years have already begun thawing. NOTES In the Canadian Arctic, layers of permafrost that scientists expected to remain frozen for at least 70 years have already begun thawing. The once-frozen surface is now sinking and dotted with melt ponds and…

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.…
