Reynard Loki – Trump Declares All-Out War on Environment With Fossil Fuel-Loving, Climate Change-Denying Cabinet Nominees

Scientists warn in a major new reportthat the increasingly rapid melting of Arctic ice could potentially be irreversible and have severe implications not just for Arctic ecosystems, but for the entire planet.

“The warning signals are getting louder,” said Marcus Carson of the Stockholm Environment Institute and one of the lead authors of the report, adding that these developments “also make the potential for triggering [tipping points] and feedback loops much larger.”

Researchers monitoring Arctic weather stations ...

Reindeer shrink as climate change in Arctic puts their food on ice

Reindeer are shrinking on an Arctic island near the north pole as a result of climate change that has curbed the amount of winter food available to the animals, scientists said on Monday.

The average weight of adult reindeer on Svalbard, a chain of islands north of Norway, fell from 55kg (121lb) to 48kg (106lb) in the 1990s as part of sweeping changes to Arctic life while temperatures rose, they said.

“Warmer summers are great for reindeer but ...

STACY MORFORD – When Permafrost Melts, What Happens to All That Stored Carbon?

The Arctic’s frozen ground contains large stores of organic carbon that have been locked in the permafrost for thousands of years. As global temperatures rise, that permafrost is starting to melt, raising concerns about the impact on the climate as organic carbon becomes exposed. A new study is shedding light on what that could mean for the future by providing the first direct physical evidence of a massive release of carbon from permafrost during a warming spike at the end ...

Alex Kirby – Arctic Tipping Points Put Earth at Risk

LONDON—If the world fails to slow the pace of climate change very soon by cutting emissions of the greenhouse gases that are heating the planet, Arctic tipping points threaten to overwhelm the region, new research reveals.

Not only that—the authors of the Arctic Resilience Report say the changes that are liable to affect the high northern latitudes could also trigger drastic changes worldwide.

The report, written by an international research team, is a project of the Continue Reading →

Chris Mooney and Jason Samenow – The North Pole is an insane 36 degrees warmer than normal as winter descends

This story has been updated.

Political people in the United States are watching the chaos in Washington in the moment. But some people in the science community are watching the chaos somewhere else — the Arctic.

It’s polar night there now — the sun isn’t rising in much of the Arctic. That’s when the Arctic is supposed to get super-cold, when the sea ice that covers the vast Arctic Ocean is supposed to grow and thicken.

But in fall of 2016 — ...

Tim Radford – Arctic Ocean could be ice-free before mid-century

LONDON, 5 November, 2016 Two scientists have worked out what it would take to melt all the ice in the Arctic Ocean.

If their sums are right, then by the time human beings have burned enough fossil fuels to add 1,000 billion tons of carbon dioxide to the atmosphere, the Arctic Ocean will be free of ice in September – the annual minimum – and the world’s shipping will have a ...

Tim Radford – Arctic Warming Gives U.S. and Europe the Chills

LONDON—Warming in the Arctic—one of the fastest-warming regions on the planet—could be heightening the chances of extreme winters in Europe and the US.

As the Arctic warms, the stratospheric jet stream that brings occasionally catastrophic ice storms and record snow falls to the eastern United States could also be on the move, according to new research in the journal Nature Climate Change.

The phenomenon is a natural one. Some years the track of the jet stream ...

PETER WADHAMS – As Arctic Ocean Ice Disappears, The Global Climate Impacts Intensify

THE NEWS LAST WEEK THAT SUMMER ICE COVERING THE ARCTIC OCEAN WAS TIED FOR THE SECOND-LOWEST EXTENT ON RECORD IS A SOBERING REMINDER THAT THE PLANET IS SWIFTLY HEADING TOWARD A LARGELY ICE-FREE ARCTIC IN THE WARMER MONTHS, POSSIBLY AS EARLY AS 2020.
After that, we can expect the ice-free period in the Arctic basin to expand to three to four months a year, and eventually to five months or more.

Since my days measuring the thickness of Arctic ...

Jeff Masters & Bob Henson – February Smashes Earth’s All-Time Global Heat Record By A Jaw-Dropping Margin

On Saturday, NASA dropped a bombshell of a climate report. February 2016 has soared past all rivals as the warmest seasonally adjusted month in more than a century of global recordkeeping. NASA’s analysis showed that February ran 1.35°C (2.43°F) above the 1951-1980 global average for the month, as can be seen in the list of monthly anomalies going back to 1880. The previous record was set just last month, as January 2016 came in 1.14°C ...

It’s Official: This Winter Was America’s Warmest on Record

This winter was the warmest on the record for the continental U.S., new data from the National Oceanic and Atmospheric Administration shows, as average temperatures climbed nearly 5 F above normal.

Every state in the lower 48 saw temperatures at least 1.7 F above average. New England lead the pack, with all six states experiencing the warmest winter ever. Alaska was a ...
