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Press science writer Seth Borenstein, who said on Twitter that he would not cover it — primarily because it had not yet been peer-reviewed, a process that allows other scientists to critique the work.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.”
“James Hansen’s new paper ratcheting up future sea level rise numbers is consistent with the new strategy of the global warming activists. Given that current sea level rise rates are not alarming, the only way climate activists can claim anything is ‘worse than we thought’ is to make more dire predictions of the future.
Simply making scarier predictions of the future in order to alarm policymakers is not ‘good science.’ Claiming that climate change impacts are ‘worse than we thought’ because predictions are now more frightening is a well worn playbook of the climate movement.
Simply put, when current reality fails to alarm, make scarier and scarier predictions of the distant future.
It is not surprising that James Hansen — a man who has been arrested nearly half a dozen times protesting ‘global warming’ and who has endorsed a book calling for ridding the world of industrial civilization — would continue to make scary predictions. The world needs to take a collective yawn at Hansen’s latest claims and ask how in the world was this man ever allowed to be in charge of the NASA temperature datasets!” – End Morano statement.
Global Warming Establishment severs ties with Hansen on sea level rise scare study:
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.”

Hansen’s “scientific” paper prescribes global political policy of “near-global” “carbon fee or tax”:
Warming leads to Cooling: Sea level rise could lead to a cooler, stormier world — Says unpublished work from NASA’s Jim Hansen – ‘A catastrophic rise in sea level before the end of the century could have a hitherto-unforeseen side effect. Melting icebergs might cool the seas around Greenland and Antarctica so much that the average surface temperature of the entire planet falls by a few degrees’.
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’
NASA’s resident ex-con: Top NASA global warming scientist James Hansen arrested (again) in White House protest over pipeline — $180,000 taxpayer-paid salary – ‘Arrested alongside actress Daryl Hannah; Adam Werbach, founder of Sierra Club; Bill McKibben’ — ‘Hansen has been arrested at least 3 times before in protests over climate issues, in 2009, 2010, & 2011′

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.
Regardless, even the IPCC concedes that there was no significant anthropogenic influence on climate prior to 1950, thus man is not be responsible for sea level rise beginning 150-200 years ago, at the end of the Little Ice Age.
The sea level rise over the past ~200 years shows no evidence of acceleration, which is necessary to assume a man-made influence. Sea level rise instead decelerated over the 20th century, decelerated 31% since 2002 and decelerated 44% since 2004 to less than 7 inches per century. There is no evidence of an acceleration of sea level rise, and therefore no evidence of any man-made effect on sea levels. Sea level rise is primarily a local phenomenon related to land subsidence, not CO2 levels. Therefore, areas with groundwater depletion and land subsidence have much higher rates of relative sea level rise, but this has absolutely nothing to do with man-made CO2.
– [Climate Depot Note: According to tide gauges, Sea Level is rising LESS than the thickness of one nickel (1.95 mm thick) per year or about the thickness of one penny (1.52 mm thick) a year. According to satellite info it is rising slightly more than two pennies a year (3.04 mm)]

NASA’s James Hansen to Retire – Marc Morano Statement: ‘Celebrate! It’s A Happy Day for Science! Hansen’s sad legacy will serve as a cautionary tale for future scientists. Hansen chose ideology, activism, stagecraft and handcuffs over science. He will be sorely missed by global warming skeptics, as he made our life so much easier by just being himself. NASA & Science deserved much better than James Hansen.’

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.’
Former NASA Scientist James Hansen urges young people to threaten fossil fuel CEOs with criminal prosecution for supporting skeptics – Hansen: ‘Young people can sue governments, industry or individuals for violating their rights’ — ‘Human-made climate change…has become a clear case of intergenerational injustice; these fundamental rights could be the basis for forcing government actions’
James Hansen denounces ‘big green’: ‘Large environmental orgs have become one of the biggest obstacles to solving the climate problem’ – Hansen: ‘After I joined other scientists in requesting the leaders of Big Green to reconsider their adamant opposition to nuclear power, and was rebuffed, I learned from discussions with them the major reason: They feared losing donor support. Money, it seems, is the language they understand. Thus my suggestion: The next time you receive a donation request, doubtless accompanied with a photo of a cuddly bear or the like, toss it in the waste bin and return a note saying that you will consider a donation in the future, if they objectively evaluate the best interests of young people and nature.’
