On a predictably gorgeous South Florida afternoon, Coral Gables Mayor Jim Cason sat in his office overlooking the white-linen restaurants of this affluent seaside community and wondered when climate change would bring it all to an end. He figured it would involve a boat.

In about the last 100,000 years, there have been 23 abrupt temperature changes in Greenland ice cores. In those moments, the temperature abruptly jumped or fell 9 to 14 degrees Fahrenheit across the planet and 25 to 35 degrees Fahrenheit in Greenland. The changes typically took decades to generations, but at their most extreme, they only took two to three years.

According to today’s report from NASA’s global temperature monitor, March of 2017 was the second hottest such month recorded in the 137 year climate record.

Scientists examining satellite images of one of Greenland’s largest glaciers believe they have found an unexpected new crack in its floating ice shelf that could contribute to a dramatic break in coming years.

On a glorious January morning in 2015, the Australian icebreaker RSV Aurora Australis was losing a battle off the coast of East Antarctica. For days, the ship had been trying to push through heavy sea ice. It rammed into the pack, backed up and crashed forward again. But the ice, several metres thick, hardly budged. Stephen Rintoul, an oceanographer at the University of Tasmania in Hobart, Australia, nearly gave up his goal — to reach a part of the continent that had thwarted all previous expeditions. “I really thought that would be it,” he says. “It’d be another failed attempt.”

"Greenland by itself has enough ice to cause many meters of sea level rise. If you live near the coast, the question of “when” is really important. This paper suggests that “when” may be sooner than we hoped."

(An excellent, authoritative summary of much recent science discussions on Arctic changes and implications. Geoengineering (in a widel definition) offered, not as a technical solution, but as a last hope....it's a perspective!)

A new international research study, including change experts from the University of Leeds, University of Exeter and the Met Office, reveals that permafrost is more sensitive to the effects of global warming than previously thought.

The study, published today in Nature Climate Change, suggests that nearly 4 million square kilometres of frozen soil—an area larger than India—could be lost for every additional degree of global warming experienced.

The largest glacier in Greenland is even more vulnerable to sustained ice losses than previously thought, scientists have reported.

Jakobshavn glacier, responsible for feeding flotillas of icebergs into the Ilulissat icefjord — and possibly for unleashing the iceberg that sank the Titanic — is an enormous outlet for the larger Greenland ice sheet, which itself contains enough ice to raise seas by more than 20 feet.
