Sea levels are rising 60% faster than estimated

    But what do the UNSKEWED polls say? :confused: :confused:

    Sea levels are rising 60 per cent faster than the UN's climate panel forecast, scientists warn.

    Satellite measurements show that sea levels are actually rising at an alarming rate of 3.2 mm a year compared to the estimate of 2 mm a year in the Intergovernmental Panel on Climate Change's fourth assessment report (AR4), researchers said.

    The researchers, from the Potsdam Institute for Climate Impact Research, Tempo Analytics and Laboratoire d'Etudes en Geophysique et Oceanographie Spatiales involved an analysis of global temperatures and sea-level data over the past two decades, comparing them both to projections made in the IPCC's third and fourth assessment reports.

    Results were obtained by taking averages from the five available global land and ocean temperature series.

    After removing the three known phenomena that cause short-term variability in global temperatures - solar variations, volcanic aerosols and El Nino/Southern Oscillation- the researchers found that the overall warming trend at the moment is 0.16 degree Celsius per decade, which closely follows the IPCC's projections.

    Satellite measurements of sea levels showed a different picture, however, with current rates of increase being 60 per cent faster than the IPCC's AR4 projections.

    Satellites measure sea-level rise by bouncing radar waves back off the sea surface and are much more accurate than tide gauges as they have near-global coverage; tide gauges only sample along the coast.

    Tide gauges also include variability that has nothing to do with changes in global sea level, but rather with how the water moves around in the oceans, such as under the influence of wind.

    The study also found that it is very unlikely that the increased rate is down to internal variability in our climate system and also shows that non-climatic components of sea-level rise, such as water storage in reservoirs and groundwater extraction, do not have an effect on the comparisons made.

    "This study shows once again that the IPCC is far from alarmist, but in fact has under-estimated the problem of climate change. That applies not just for sea-level rise, but also to extreme events and the Arctic sea-ice loss," lead author of the study, Stefan Rahmstorf, said in a statement.

    The study was published in the journal Environmental Research Letters.

    Looks like another insane promise from the annointed one is not coming to fruition, Obamas election in 2008 was supposed to be the moment when the sea levels began to recede, and the planet began to heal, instead just like with everything else Obama, we are worse off than we were 4 years ago.

  4. OMG rising 3 times the length of your dick in one whole year, what a disaster .

    Can't wait for them to make a movie about a 3 mm rise in the ocean.

    Just out of curiosity how far away from the earth did the moon move last year?

    3.2 mm huh? At that rate how long before I'm on beachfront property here at 1000 ft above sea level?
  6. And the GOP never worried about Nate Silver's polling data. How did that work out?

    I'm not a nutcase global warming type, however, I don't see any reason to not make some solid efforts to help the planet. Sounds sort of Conservative to me.
  7. WTF are you talking about, help the earth?
  8. Possibly helping, definitely not hurting IMO. I'm just saying that common sense things like recycling, clean coal filters, catalytic converters, alternative power sources, and all that, just seem to make sense, And can't really hurt.

    Not giving money to oil companies nor to new energy types, just for the sake of giving away money. Supporting alternative fuel sources, even natgas can be a good thing however.
  9. Honestly the claim made in this story is wholly unconvincing of anything other than an attempt to persuade through innumeracy or just the exploitation of sheer ignorance of readers.

    The claim of sea levels rising is just ridiculous on the face of it.

    Why didn't they put that in terms of cubic volume increase?
  10. These idiots want to save the planet but they don't seem to understand that nothing they can do or force the rest of us to do will make any difference. they act like it's just a matter of closing a few coal plants, and presto, problem solved. Good luck seeling that to china and india.

    I can just hear obama blaming republicans and evil utilities when utility rates go up by ten times and demanding programs to help the poor pay for them.

    Even if all this is true and accurate, which we know very well it isn't, based on our experience with other supposed crises, it would be far cheaper to alleviate the effects of rising sea water directly rather than try to alter the climate.
