The Earth Day 2017 March for Science signals resistance to Donald Trump’s sharp infusion of irrationality into the national discourse. Official support for climate-change denial and other anti-science agendas has suddenly become much more explicit. At the same time, many protestors recognize a continuity linking Trump’s bizarre bluster with a pre-existing condition sometimes referred to as the “Republican war on science.”

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.

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!)
