Seas are now rising faster than they have in 2,800 years, scientists say

By Chris Mooney 22 February 2016 (Washington Post) – A group of scientists says it has now reconstructed the history of the planet’s sea levels arcing back over some 3,000 years — leading it to conclude that the rate of increase experienced in the 20th century was “extremely likely” to have been faster than during […]

Effects of human carbon emissions could last 10,000 years – ‘Our greenhouse gas emissions today produce climate-change commitments for many centuries to millennia’

CORVALLIS, Oregon, 8 February 2016 (OSU) – At the rate humans are emitting carbon into the atmosphere, the Earth may suffer irreparable damage that could last tens of thousands of years, according to a new analysis published this week. Too much of the climate change policy debate has focused on observations of the past 150 […]

Blizzard Jonas and the slowdown of the Gulf Stream System

By Stefan Rahmstorf24 January 2016 (RealClimate) – Blizzard Jonas on the U.S. east coast has just shattered snowfall records. Both weather forecasters and climate experts have linked the high snowfall amounts to the exceptionally warm sea surface temperatures off the east coast. In this post I will examine a related question: why are sea surface […]

In Greenland, a climate change mystery with clues written in water and stone

By Ari Daniel24 January 2016 (PRI) – The breakfast on the edge of Greenland’s massive ice sheet is ordinary — granola, yogurt, bread and jam. Everything else here is anything but. “You’d pay a million bucks for a view like this,” says Gordon Hamilton, from the University of Maine by way of Scotland. “Pretty nice […]

In Greenland, another major glacier comes undone – ‘The changes are staggering and are now affecting the four corners of Greenland’

12 November 2015 (NASA) – It’s big. It’s cold. And it’s melting into the world’s ocean. It’s Zachariae Isstrom, the latest in a string of Greenland glaciers to undergo rapid change in our warming world. A new NASA-funded study published today in the journal Science finds that Zachariae Isstrom broke loose from a glaciologically stable […]

The ‘blue blob’: Changes in Atlantic happening sooner than expected – ‘We like to think of climate as an elephant moving slowly along, but the ocean system is not that simple’

[cf. Why some scientists are worried about a surprisingly cold ‘blob’ in the North Atlantic Ocean – ‘The fact that a record-hot planet Earth coincides with a record-cold northern Atlantic is quite stunning’] By Lisa Sorg4 November 2015 (Coastal Review) – There it is, hanging out in the northern Atlantic Ocean, off the southern tip […]

Are we experiencing exponentially increasing sea level rise?

Guest post by Alexander Ač9 October 2015 (Desdemona Despair) – Sea level rise (SLR) is recognized as one of the least adaptable impacts of ongoing climate change. Once a certain area is permanently flooded with saline water, people have to leave. Forever. Thus SLR projections gain a lot of attention not only in the climate […]

Why some scientists are worried about a surprisingly cold ‘blob’ in the North Atlantic Ocean – ‘The fact that a record-hot planet Earth coincides with a record-cold northern Atlantic is quite stunning’

By Chris Mooney25 September 2015 (Washington Post) – It is, for our home planet, an extremely warm year. Indeed, last week we learned from the National Oceanic and Atmospheric Administration that the first eight months of 2015 were the hottest such stretch yet recorded for the globe’s surface land and oceans, based on temperature records […]

NASA zeroes in on ocean rise – ‘It’s pretty certain we are locked into at least 3 feet of sea level rise, and probably more’

26 August 2015 (NASA/JPL) – Seas around the world have risen an average of nearly 3 inches (8 centimeters) since 1992, with some locations rising more than 9 inches (25 centimeters) due to natural variation, according to the latest satellite measurements from NASA and its partners. An intensive research effort now underway, aided by NASA […]

Climate scientists: When the end of human civilization is your day job – ‘The business-as-usual world that we project is really a totally different planet’

By John H. Richardson7 July 2015 (Esquire) – The incident was small, but Jason Box doesn’t want to talk about it. He’s been skittish about the media since it happened. This was last summer, as he was reading the cheery blog posts transmitted by the chief scientist on the Swedish icebreaker Oden, which was exploring […]
