This is a picture from a movie about Captain Nemo of 20,000 Leagues Under the Sea fame. Well according to some real scientist, we won’t be needing to move into a submarine or build any underwater cities, which is what “alarmists” Al Gore and James Hansen would like you to believe will happen by the end of the century, caused, of course, by global warming and CO2.
As an example, let us say that ice sheet melting adds 1 centimetre to sea level for the decade 2005 to 2015, and that this doubles each decade until the West Antarctic ice sheet is largely depleted. This would yield a rise in sea level of more than 5 metres (16 feet) by 2095.
The experts in seas/oceans estimate a potential 4.7 inch to 39 inch rise over 21st century – this is certainly a sea level rise range that humans can deal with, easily. And, most significantly, this is a range based on historical sea levels that actually occurred during past warmer periods. What does this tell us? The true experts are predicting a maximum sea level rise far below the non-expert opinions (propagandist myths) of fanatical warming activists, such as Gore and Hansen.
That is a far, far cry from 16 to 20 feet. We’re talking less than 1/2 foot to a little over 3 feet. Quite a difference form 15 to 20 feet or more!
To simplify what these scientist did, is they looked at past data from when the climate was similar and looked at what the actual sea-level rise then…
Turning to the IPCC — the most recent report of which predicts a global warming of somewhere between 1.1 and 6.3°C for the 21st century — the PALSEA group writes that “the last time that a global warming of comparable magnitude occurred was during the termination of the last glacial period,” which consisted of “a series of short, sharp steps on millennial to centennial timescales.” Hence, they looked at what is known about sea level change during the Bolling-Allerod and post-Younger Dryas/early Holocene periods, because they say “the magnitude and rate of warming during these periods are most closely analogous to the magnitude and rate of anthropogenic warming [that is predicted to occur] over the coming centuries;” and this comparison ruled out any type of exponentially increasing sea level response, pointing more towards an asymptotic response, where the sea level rise is high initially but gradually levels off.
Realistically, their study states it will take a lot longer than a century for any significant rise to occur. Even the IPCC predicted only -0.01 to 0.17 m over the century.
Regardless which one you believe, either one easily proves that Gore and Hansen are full of alarmist bullshit designed to freak-out the average person so they’ll donate money to prevent it and move into caves with hot and cold running bats to save the earth.
Well, at least it’s one CO2 Insanity episode put to bed by a dose of reality.
