New Science Suggests the Ocean Could Rise More -- and Faster -- Than We Thought (washingtonpost.com)

Chris Mooney, writing for the Washington Post: Climate change could lead to sea level rises that are larger, and happen more rapidly, than previously thought, according to a trio of new studies that reflect mounting concerns about the stability of polar ice. In one case, the research suggests that previous high end projections (PDF) for sea level rise by the year 2100 -- a little over three feet -- could be too low, substituting numbers as high as six feet at the extreme if the world continues to burn large volumes of fossil fuels throughout the century (Editor's note: the link could be paywalled). "We have the potential to have much more sea level rise under high emissions scenarios," said Alexander Nauels, a researcher at the University of Melbourne in Australia who led one of the three studies. His work, co-authored with researchers at institutions in Austria, Switzerland, and Germany, was published Thursday in Environmental Research Letters. The results comprise both novel scientific observations -- based on high resolution seafloor imaging techniques that give a new window on past sea level events -- and new modeling techniques based on a better understanding of Antarctic ice.

    So these predictions are based on events that haven't happened. Got it...

    That is rather entailed in the world "prediction".

    New Science Suggests the Ocean Could Rise More -- and Faster -- Than We Thought

    Maybe. Possibly.

    But aren't we already suppose to be under ten feet of water?

    Huh? Where did you get that? Nobody predicted ten feet-- over three meters!-- of sea level rise by 2017.

    The very first IPCC report-- back in 1990--predicted "an average rate of global mean sea level rise of about 6 cm per decade over the next century (with an uncertainty range of 3 – 10 cm per decade), mainly due to thermal expansion of the oceans and the melting of some land ice. The predicted rise is about 20 cm ... by 2030, and 65 cm by the end of the next century."

    The most recent (5th, 2014) report (here https://www.ipcc.ch/pdf/assess... ) says 25 cm to 70 cm by 2100. (That's the one that this news item is reacting to).

    Nobody predicted 10 feet by 2017-- you should look back and find who told you that had been the prediction and never believe them again.
