According to James Hansen has insisted for 40 years that man's emissions of carbon dioxide are the sole reason the Earths temperatures are rising.
He is wrong. In 1988 he testified that global temperatures averaged 59 degrees Fahrenheit, Last year, the global temperature was 55.39 degrees Farenheit. That's according to global warming alarmists. The whole global temperature idea is nonsense. It is a survey of thermometers of varying degrees of accuracy, ditto the satellite data.
But now he is doubling down on the stupid by saying the oceans will rise by 10 feet in 50 years.
From the Washington Post:
Hansen — who retired in 2013 from his NASA post, and is currently an adjunct professor at Columbia University’s Earth Institute — is publishing what he says may be his most important paper. Along with 16 other researchers — including leading experts on the Greenland and Antarctic ice sheets — he has authored a lengthy study outlining an scenario of potentially rapid sea level rise combined with more intense storm systems.From reality:
Contrary to the chorus of climate alarmists, the Arctic ice cap has not, by now, completely disappeared: in actual fact it has been growing rapidly lately, by an entire third just in 2013 and more since.
"It would suggest that sea ice is more resilient perhaps. If you get one year of cooler temperatures, we've almost wound the clock back a few years on this gradual decline that's been happening over decades," ice scientist Rachel Tilling tells the BBC. The Beeb was reporting on newly published updated research which has confirmed the Arctic ice's remarkable resurgence over the last couple of years, for all that last year was tied for warmest-ever with 2005 and 2010.
The Arctic ice has indeed cheered up a bit, particularly in thickness of the key areas north of Greenland and Canada, which had been getting nearly as thin as the stuff north of Siberia - which regularly breaks up enough to let ships through, though they generally have to be escorted by icebreakers. Thus actual ice volumes are looking especially good.
Arctic ice has also stabilised in area, which is a marked change from much of last decade when the northern sea ice extent over time seemed to be in free fall.Carbon dioxide levels are not high enough to melt the Arctic. Every prediction Hansen has made has been wrong. Embarrassingly so. And yes, dangerously so because he lobbies for policies that put people and species at unnecessary risk. For example, the quest for biofuels is deforesting the Philippines.
