Eight to Eighteen Decades Before Irreversible Planetary Catastrophe

Links are available to Dr. James Hansen's, (and co-authors), alarming new paper on climate change presenting findings suggesting a range of some eight to 18 decades before Earth reaches a point of no return, ("locked-in"), of catastrophic consequences caused by human beings' fossil-fuel energy systems' emitting gasses changing the atmosphere.

'Consequences include sea level rise of several meters, which we estimate would occur this century or at latest next century, if fossil fuel emissions continue at a high level. That would mean loss of all coastal cities, most of the world’s large cities and all their history. A more immediate threat is the likelihood of shutting down the oceans overturning circulations in the North Atlantic and Southern oceans. That’s where superstorms come in ... .'

Hansen's new paper is entitled Ice Melt, Sea Level Rise and Superstorms: The Threat of Irreparable Harm:

• Nineteen-page abbreviation of Ice Melt, Sea Level Rise and Superstorms: The Threat of Irreparable Harm, with links to media, full paper, and video included
• Final Paper
• Video Discussion
• Dr. Hansen’s webpage, communications, etc. 
• Justin Gillis' piece in the New York Times 
• Amelia Urry's piece in the Grist 

It is possible a massive change in the energy production systems on a global scale could alter the consequences, suggests the paper.
