Eight Years Since James Hansen Predicted 25 Metres Of Sea Level Rise


Will oceans surge 59 centimetres this century – or 25 metres?
The new climate: A controversial study suggests rapid polar meltdown and rising sea levels

Richard Peltier

When Al Gore predicted that climate change could lead to a 20-foot rise in sea levels, critics called him alarmist. After all, the International Panel on Climate Change, which receives input from top scientists, estimates surges of only 18 to 59 centimetres in the next century.

But a study led by James Hansen, the head of the climate science program at the National Aeronautics and Space Administration’s Goddard Institute for Space Studies in New York and a professor at Columbia University, suggests that current estimates for how high the seas could rise are way off the mark – and that in the next 100 years melting ice could sink cities in the United States to Bangladesh.

“If we follow ‘business-as-usual’ growth of greenhouse gas emissions,” he writes in an e-mail interview, “I think that we will lock in a guaranteed sea-level rise of several metres, which, frankly, means that all hell is going to break loose.”

The scientific basis for this idea – which Prof. Hansen and five co-authors gleaned from geological records, ice core samples and analysis of the sea floor – is outlined in a recent paper published by the British journal Philosophical Transactions of the Royal Society.

In stark contrast to estimates put forward by the IPCC, Prof. Hansen and his colleagues argue that rapidly melting ice caps in Antarctica and Greenland could cause oceans to swell several metres by 2100 – or maybe even as much as 25 metres, which is how much higher the oceans sat about three million years ago.

    In truth ; it’s just as likely to fall by a few centimetres by 2030 and then rise & fall again,, in all probability, the end of the Century could be unremarkably close to the level today. Then again, I don’t play with myself and I’m not in someone else’s pockets…

    25 meters? 😆

    I would love to see the model that produced that!

    Only in Hansen’s model, the bowl would actually be gaining water.

    Oceans play a very important role on climate change, as shown here, http://oceansgovernclimate.com/not-the-sun-the-ocean-is-the-driver/, for example, but I guess that I will see that scenario only in sci-fi movies. Or should I call them cli-fi movies…..

    Thanks to questions raised by Steven Goddard and a few other brave skeptics, we know WE HAVE NOTHING TO FEAR BUT FEAR ITSELF:

    Today’s world leaders are only POWERLESS TYRANTS using public funds to pay spineless news reporters and puppet scientists to hide their powerlessness from the public.

    Precise experimental data show the Sun’s pulsar core is the benevolent Creator, Destroyer & Sustainer of every atom, life and planet in the Solar System, controlling our heartbeats and Earth’s climate:
