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. This strange story of smoke, dust and algae looks at the lesser-known half of a positive feedback loop: not only does climate change make fires bigger and badder,…

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…

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…

Jet Stream Stalled over Sweden Climate Weather Connection Explained

This heatwave across much of the northern hemisphere could continue for weeks, and possibly even months. And accelerated warming in the Arctic compared to the rest of the planet could be a key contributor. https://www.newscientist.com/article/2174889-warming-arctic-could-be-behind-heatwave-sweeping-northern-hemisphere/ Jennifer Francis (Rutgers University), speaks March 2018 about weather changes. And how are those related to climate change? Full talk…
