Former Top NASA Scientist James Hansen Predicts Catastrophic Rise In Sea Levels – ‘Projects sea levels rising as much as 10 feet in the next 50 years.’ – The paper has already ruffled some, including Associated Press science writer Seth Borenstein, who said on Twitter that he would not cover it — primarily because it had not yet been peer-reviewed, a process that allows other scientists to critique the work. The Washington Post’s Chris Mooney asked other climate experts to weigh in on the paper. While many said it raised key discussion points, Kevin Trenberth of the National Center for Atmospheric Research called it “provocative and intriguing but rife with speculation and ‘what if’ scenarios.”
Warmist publication Mashable on James Hansen’s new sea level scare paper: “..red flag..study’s conclusions so contradict [UN IPCC] consensus views expressed last year.”
Mashable’s Andrew Freedman: ‘The godfather of global warming’s scary sea level rise prediction is getting the cold shoulder.”
NYT’s Andrew Revkin on Hansen’s sea level scare paper: “Associated Press, The New York Times, the BBC and The Guardian..among those who steered clear of [Hansen] study”
NYT: UN IPCC Lead Author Kevin Trenberth on Hansen sea level rise paper: “Rife with speculation..many conjectures & huge extrapolation based on quite flimsy evidence.”

Rebuttal: Examination of the data from the paper, however, shows the range of proxy sea levels is approximately 10 meters, far too large to discern the tiny ~1.5 mm/yr sea level rise over the past 150 years. The authors instead assume from other published studies of tide gauge measurements that the ~1.5 mm/yr sea level rise over the past 150+ years began at that point in time. Other papers find sea levels rising only 1.1-1.3 mm/yr over the past 203 years, and without acceleration.
Background on Hansen: 1) NASA’s James Hansen, a muse to Eco-Terrorists?! Watch Now: Morano on Fox News: ‘NASA’s resident ex-con James Hansen is inspiring these people to potential acts of eco terrorism’ — Morano: ‘He was arrested for the 3rd or 4th time this past week protesting the pipeline. Hansen has endorsed a book calling for ridding the world of industrial civilization, for blowing up dams and razing cities to the ground and turning off our greenhouse gas machine’ —
2) Flashback: NASA scientist James Hansen endorses book which calls for ‘ridding the world of Industrial Civilization’ – Hansen declares author ‘has it right…the system is the problem’ — Book proposes ‘razing cities to the ground, blowing up dams and switching off the greenhouse gas emissions machine —
3) Flashback: Greenie David Roberts of Grist turns on NASA’s Hansen: ‘I know I’m not supposed to say this, but Hansen managed his transition from scientist to activist *terribly*. All influence lost’ —
New York Times – June 11, 1986: “Average global temperatures would rise by one-half a degree to one degree Fahrenheit from 1990 to 2000 if current trends are unchanged, according to Hansen’s findings. Dr. Hansen said the global temperature would rise another 2 to 4 degrees in the following decade.”

Hansen to CNN: Selling nuclear energy to environmentalists is a tough pitch. Hansen acknowledged that many of them won’t easily buy into it. Parts of the community operate like ‘a religion of sorts, which makes it very difficult,’ Hansen said. ‘They’re not all objectively looking at the pros and cons.’
