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…

Video: Enhanced Seismic Activity Observed in Alaska Due To Climate Change

With news breaking that Alaska just had its warmest March to May on record with a statewide average temperature of 32.6°F, 8.6°F above the long-term average – the previous warmest spring in Alaska was in 2016, one must ask how this performs in relation to seismicity. Read the study excerpts of, Enhanced Seismic Activity Observed in Alaska Due…

Multi Meter Sea Level Rise, Antarctic Sea Ice & Ice Melt Acceleration

A pair of new studies released on Monday share a same ominous message — that our planet’s ice is melting at an alarming rate, which is bad news for global sea levels. https://edition.cnn.com/2019/01/14/world/climate-change-antarctica-ice-melt-twin-studies/index.html Narration by Cormac Bren Antarctic ice-sheet sensitivity to obliquity forcing enhanced through ocean connections https://www.nature.com/articles/s41561-018-0284-4 Four decades of Antarctic Ice Sheet mass…

Eric Rignot: Response of the Great Ice Sheets to Climate Warming (2014)

In 2014, as part of the Discover the Physical Sciences Breakfast Lecture Series at the University of California, climate researcher Eric Rignot (NASA/JPL) outlined our understanding of changes in the major cryosphere hotspots in Antarctica and Greenland, in his talk titled “Response of the Great Ice Sheets to Climate Warming”. Read about his newest 2019…

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…

How burning Forests melt Ice Sheets

Forest fires can melt glaciers thousands of miles away by changing the colour of the ice – all thanks to a heavy little particle called black carbon. How burning Forests melt Ice Sheets How burning Forests melt Ice Sheets This strange story of smoke, dust and algae looks at the lesser-known half of a positive…

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

Did a Greenland Asteroid Cause Abrupt Warming Last Ice Age?

We report the discovery of a large impact crater beneath Hiawatha Glacier in northwest Greenland. From airborne radar surveys, we identify a 31-kilometer-wide, circular bedrock depression beneath up to a kilometer of ice http://advances.sciencemag.org/content/4/11/eaar8173 Hiawatha Glacier https://en.wikipedia.org/wiki/Hiawatha_Glacier Sources Discovering a massive meteorite crater https://www.youtube.com/watch?v=hQ9maLsIcts Massive crater under Greenland’s ice points to climate-altering impact in the…

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…
