Last summer’s 600 billion tons of ice loss in Greenland raised global sea levels by nearly a 10th of an inch — or 2.2 millimeters — in two months

The Hill, March 2020. Greenland lost 600 billion tons of ice last summer due to an exceptionally warm season, according to a study released Wednesday.  The study was published Wednesday in the journal Geophysical Research Letters.  The data was drawn from satellites designed to measure changes to the earth’s gravitational pull that result from changes in mass, including water.  Last summer’s …

Arctic Permafrost Is Melting so Fast, It’s Gouging Holes in the Landscape: New research finds carbon emissions estimates should be doubled

 Jordan Davidson Feb. 04, 2020, SCIENCE Permafrost is thawing so fast, in can turn a forest into a lake in the course of one month. Flickr / CC BY-NC 2.0 Current estimates of carbon emissions from melting Arctic permafrost rely on a model of a gradual melt. New research has found abrupt thawing of permafrost which means carbon emissions estimates should be doubled. The rate at …

More than half of the climate tipping points identified a decade ago are now “active,” a group of leading scientists have warned

By Tim Radford, Climatenewsnetwork.netNovember 30, 2019 | EDUCATE! Changes afoot now in at least nine areas could drastically alter the Earth’s climate. There’s no time left to act on these tipping points. LONDON, 28 November, 2019 – On the eve of a global climate summit in Madrid, seven distinguished climate scientists have issued an urgent warning of approaching planetary tipping points: within a few years, they …

Flash drought: ‘Really wet to really dry, really fast’, and even as the amount of damage increases, governments and residents have less time to repair before the next storm hits

Luebehusen plotted what experts call a “flash drought.” While not fully understood, these quick-developing droughts might be another signature of climate change. Experts say a flash drought often begins as a pin-sized swelter in one county, then expands like an amoeba across the landscape. The droughts are often accompanied by erratic precipitation over sharply defined geographic areas. The downpours can …

Climate Change Damage Is About to Get a Lot Worse, IPCC Warns

From Antarctica to the Oceans, Dangerous shifts are already underway. If fossil fuel use continues at this pace, the world will see sweeping consequences for nature and humans, report authors say. Sabrina Shankman SEP 25, 2019 As the planet warms, diverse ecosystems—from mountain glaciers to the icy Arctic to the oceans—are already seeing dangerous effects from climate change. Future warming will …

New climate models set to replace those used in current UN projections say we are on track for average temp rises to 7 C above pre-industrial levels

“Unfortunately, our global failure to implement meaningful action on climate change over recent decades has put us in a situation where what we need to do to keep warming to safe levels is extremely simple,” said Dr. Joeri Rogelj, an associate professor at Imperial College London and an IPCC lead author. “Global greenhouse gas emissions need to decline today rather …

Five Climate Myths Debunked

The Conversation, 2019 The science of climate change is more than 150 years old and it is probably the most tested area of modern science. However the energy industry, political lobbyists and others have spent the last 30 years sowing doubt about the science where none really exists. The latest estimate is that the world’s five largest publicly-owned oil and gas companies spend about …
