MONDAY, APRIL 15, 2013   Reuters explodes the idea of global warming consensus: We don't know how the planet would respond to doubled CO2; we don't know if more clouds cause warming or cooling; maybe Chinese coal burning is cooling the planet; we don't know if the heat is hiding in the oceans, etc

COLUMN-Slowdown in warming no argument for policy change: Wynn | Reuters



(Reuters) - A recent slowdown in the rise of the Earth's surface temperatures has led some commentators to question whether scientists have exaggerated the global warming problem.
...Scientists have provided a wide range of views on how the planet could respond to a doubling of carbon dioxide levels, a measure known as climate sensitivity.
...
One area of uncertainty is whether the net effect of more clouds will lead to warming or cooling.

The record for observed surface temperatures (there are few observations in the deep oceans) in the past decade have found no evidence for an extreme response to greenhouse gases.
...There are plenty of potential causes for a blip in the warming trend besides a revised assessment of the impact of greenhouse gases.
...
Candidates include manmade aerosols from a huge increase in coal burn in the past 10 years in China (which forms hazy clouds that can reflect back sunlight and cool the Earth); changes in the El Nino Pacific Ocean weather pattern (which warms the Earth and whose last big maximum was 1998); an observed fall in stratospheric water vapour (a strong greenhouse gas); and the role of the deep oceans in masking surface warming by sequestering heat.
...
Without scientific certainty, governments will probably maintain their default positions regarding international action

WEDNESDAY, APRIL 17, 2013[size=21.52777671813965px]The madness of James Hansen: Trace amounts of CO2 may make the weather so warm that "even a person lying quietly naked in hurricane force winds would be unable to survive"; he envisions a few wealthy people desperately defending homes high in the Himalayan peaks against masses fleeing CO2-induced apocalypse

From James Hansen's latest insane rant:
I have been told of specific well-respected people who have asserted that "Jim Hansen exaggerates" the magnitude and imminence of the climate threat. If only that were true, I would be happy...CO2, the dominant climate forcing on the long run, will stay in the climate system for millennia...I was recently at a meeting that included many of the top researchers in climate change. There was universal agreement about the urgency of the climate crisis...if we burn all the fossil fuels it is certain that sea level would eventually rise by tens of meters...Venus - like conditions in the sense of 90 bar surface pressure and surface temperature of several hundred degrees are only plausible on billion - year time scales...One implication is that if we should "succeed" in digging up and burning all fossil fuels, some parts of the planet would become literally uninhabitable, with some time in the year having wet bulb temperature exceeding 35 °C. At such temperatures , for reasons of physiology and physics, humans cannot survive , because even under ideal conditions of rest and ventilation, it is physically impossible for the environment to carry away the 100 W of metabolic heat that a human body generates when it is at rest 14 . Thus even a person lying quietly naked in hurricane force winds would be unable to survive...The picture that emerges for Earth sometime in the distant future, if we should dig up and burn every fossil fuel, is thus consistent with that depicted in "Storms" -- an ice-free Antarctica and a desolate planet without human inhabitants. Although temperatures in the Himalayas may have become seductive, it is doubtful that the many would allow the wealthy few to appropriate this territory to themselvesor that humans would survive with the extermination of most other species on the planet. At least one sentence in "Storms" will need to be corrected in the next edition: even with burning of all fossil fuels the tropical ocean does not "boil". But it is not an exaggeration to suggest, based on best available scientific evidence, that burning all fossil fuels could result in the planet being not only ice - free but human-free.

Remember, you are a little rat......a no morals immoral rat.

James Hanson is a respected man, very respected man......


There lies the difference between him and his opponents.
