1/4 to 1/2 of Glaciers will Melt by 2100, raising Sea Level, As our burning of Fossil Fuels Heats Earth

Ann Arbor (Informed Comment) – A new multi-author study in Nature finds that the world’s 200,000 glaciers are melting at an increasingly alarming rate. If all of them melted, it would raise sea level by over a foot, a disaster for coastal communities around the world. And it isn’t just a matter of coasts — […]

If melting Glaciers shut down the Atlantic Gulf Stream, Extreme Climate Change Catastrophes will Follow

The Conversation

By René van Westen, Utrecht University; Henk A. Dijkstra, Utrecht University; and Michael Kliphuis, Utrecht University | – Superstorms, abrupt climate shifts and New York City frozen in ice. That’s how the blockbuster Hollywood movie “The Day After Tomorrow” depicted an abrupt shutdown of the Atlantic Ocean’s circulation and the catastrophic consequences. While Hollywood’s vision […]

How analyzing ancient and modern Polar Bear Samples Reveals the Full Scope of Global Heating

The Conversation

By Jennifer Routledge, Trent University | – The global climate is changing and the Arctic is warming rapidly. These are objectively true statements that most people have come to accept. But it is also true that Earth’s climate has never been stagnant and climate anomalies have been frequent throughout the past. How then, do we […]

416,000 Years Ago, All Greenland’s Ice Melted and Raised Sea Levels 5-20 Feet: A Warning from the Past

The Conversation

By Paul Bierman, University of Vermont, and Tammy Rittenour, Utah State University | – About 400,000 years ago, large parts of Greenland were ice-free. Scrubby tundra basked in the Sun’s rays on the island’s northwest highlands. Evidence suggests that a forest of spruce trees, buzzing with insects, covered the southern part of Greenland. Global sea […]
