Global Warming and Changes in East Antarctic Glaciers #AGU2018

https://www.youtube.com/watch?v=2P9X7lLl5Iw East Antarctica, which holds the potential of raising global sea level by almost 200 feet, has long been considered stable and unlikely to change in the future. But recent observations have hinted that East Antarctica is starting to wake. #TottenGlacier In this briefing, researchers will present new findings on how a group of glaciers…

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…

Hugh Montgomery: Are Humans Like a Virus on Planet Earth?

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.…

Trends in Hurricane Activity (2018)

Tropical cyclones, which are called hurricanes in the Atlantic, are one of the most destructive weather phenomena. This presentation will explore the links between climate and tropical cyclones, with a focus on how hurricanes and tropical cyclones have changed in the past, and what we think they will do in the future. http://www.atkinson.cornell.edu/events/ClimateChangeSem.php Speaker: Gabriel…
