The Arctic hasn’t been this hot for 3 million years – and that foreshadows big changes for the rest of the planet

By Julie Brigham-Grette and Steve Petsch | – Every year, sea ice cover in the Arctic Ocean shrinks to a low point in mid-September. This year it measures just 1.44 million square miles (3.74 million square kilometers) – the second-lowest value in the 42 years since satellites began taking measurements. The ice today covers only […]

Arctic Heat Wave: Block of Ice Twice as Big as Manhattan breaks off Greenland’s largest Ice Shelf, goes into Ocean

Juan Cole

Ann Arbor (Informed Comment) – A 42 square mile block of ice has just hived off from the Arctic’s largest ice shelf, in northeast Greenland, alarming climate scientists. That is the size of Santa Barbara, California. It is ginormous. Danish scientists are speaking ominously of “glacier disintegration.” The Geological Survey of Denmark and Greenland reports, […]

On Day Scientists Announce Melting of Greenland Ice Sheet ‘Irreversible,’ Trump to permit Arctic oil, gas Drilling

Juan Cole

Ann Arbor (Informed Comment) – The Trump administration on Monday finalized its plans to permit oil and gas drilling in the arctic wildlife reserve. This drilling will further imperil endangered species just by the setting up of the rigs, and it will desecrate land holy to the indigenous Gwich’in people, who call it “the sacred […]

Climate Emergency making you Poor: Coastal Flooding may cost up to 20% of Global Economy in coming Decades

The Conversation

By Ebru Kirezci | – Over the past two weeks, storms pummelling the New South Wales coast have left beachfront homes at Wamberal on the verge of collapse. It’s stark proof of the risks climate change and sea level rise pose to coastal areas. Our new research published today puts a potential price on the […]

New research shows the South Pole is warming faster than the rest of the world

The Conversation

By Kyle Clem | – Climate scientists long thought Antarctica’s interior may not be very sensitive to warming, but our research, published today, shows a dramatic change. Over the past 30 years, the South Pole has been one of the fastest changing places on Earth, warming more than three times more rapidly than the rest […]

The unexpected link between the ozone hole and Arctic warming

The Conversation

By Karen Smith | – One of the earliest climate model predictions of how human-made climate change would affect our planet showed that the Arctic would warm about two to three times more than the global average. Forty years later, this “Arctic amplification” has been observed firsthand. Record-breaking Arctic warming and the dramatic decline of […]

Ancient Antarctic ice melt caused extreme sea level rise 129,000 years ago – and it could happen again

The Conversation

By Chris Fogwill, Chris Turney, and Zoë Thomas | – Rising global temperatures and warming ocean waters are causing one of the world’s coldest places to melt. While we know that human activity is causing climate change and driving rapid changes in Antarctica, the potential impacts that a warmer world would have on this region […]

It is 65° F. in Antarctica and if the Thwaites Glacier Plops in, Expect 4 ft. of Sea Level Rise

Juan Cole

Ann Arbor (Informed Comment) – The Argentinean Esperanza research station in Antarctica — the South Pole — recorded a temperature of nearly 65° F. (18° C.) this week, a historic record. A single temperature record like this one is weather, and by itself would not prove much. Unfortunately, it was not a fluke. It is […]

If Global Heating Exceeds 3.6° F., Antarctica’s Melt could Raise Seas 60 Feet over Time

The Conversation

By Georgia Rose Grant and Timothy Naish | – We know that our planet has experienced warmer periods in the past, during the Pliocene geological epoch around three million years ago. Our research, published today, shows that up to one third of Antarctica’s ice sheet melted during this period, causing sea levels to rise by […]
