Forecast global temperature rise of 4C a calamity for large swaths of planet even if predicted extremes are not reachedSome of the most extreme predictions of global warming are unlikely to materialise, new scientific research has suggested, but the world is still likely to be in for a temperature rise of double that regarded as safe.
The researchers said warming was most likely to reach about 4C above pre-industrial levels if the past decade's readings were taken into account.
That would still lead to catastrophe across large swaths of the Earth, causing droughts, storms, floods and heatwaves, and drastic effects on agricultural productivity leading to secondary effects such as mass migration.

may see deaths from heat rise by as much as 20 percent in the 2020s and 90 percent by the 2080s in a worst-case scenario, a study found.The study, published this week in the journal Nature Climate Change, was done by Columbia University’s Earth Institute and the Mailman School of Public Health. Higher winter temperatures may cut cold-related mortality, though net temperature-related deaths may still climb by a third by the 2080s, according to a statement detailing the findings.
“This serves as reminder that heat events are one of the greatest hazards faced by urban populations around the globe,” said Radley Horton, a climate scientist at the Earth Institute’s Center for Climate Systems Research and a co-author.

Greenland ice melting at an expanding pace may begin cooling the North Atlantic and increasing the severity of storms by 2075, said James Hansen, the former NASA scientist who raised concerns about global warming in the 1980s.“If we stay on this path where the rate of mass loss from Greenland doubles every 10 years, we would get to a situation by about 2075 or 2080 where the mass loss is so fast that it causes the whole North Atlantic to be colder,” Hansen said in London.
The findings are from computer models using current rates of ice melt and will be detailed in a paper that Hansen plans to finish writing in the summer, he said yesterday in an interview.

Months after his state was ravaged by extreme weather, the New Jersey governor is now publicly denying climate change. Expect more of that kind of idiocy as he gears up for 2016.So now Chris Christie is a climate-change denier. He was at a ceremony Monday, just a few hours before Moore, Oklahoma got pounded for the sixth time in recent years, doing the sort of thing governors love to do—pounding the ceremonial final nail into the rebuilt boardwalk in Lavallette, New Jersey. A reporter from WNYC/New Jersey Public Radio asked him about her station’s investigative report on the state’s extreme lack of preparedness for Hurricane Sandy. Should state agencies, he was asked, have made preparations with climate change in mind?
