A scientific study conducted at the University of Reading of the interactions between aerosols and clouds shows the interaction is much weaker than most climate models assume, MRC reported. In other words, the Earth will warm considerably less than those climate models Al Gore wants us to follow.
Paul Knappenberger and Patrick Michaels of the Cato Institute, said that instead of facing Global Warming, at worst, we may be facing “global lukewarming.” These serious, reputable scientists are exposing many of the myths.
Clouds have a significant role in the workings of the earth’s climate and they have taken a major role in the computer models which are the basis for the oppressive government regulations destroying our fossil fuel industry and our way of life.
The claim is global warming will melt the ice caps and kill us all straight away. One of the things affecting clouds in the climate computer models is the interaction between aerosol and the atmosphere:
When it comes to the influence of human aerosol emissions on cloud properties, the scientific mainstream view is that aerosols modify clouds in such a way as to result in an enhanced cooling of the earth’s surface—a cooling influence which has acted to offset some portion of the warming influence resulting from human emissions of greenhouse gases (primarily from the burning of fossil fuels, like coal, oil, and natural gas to produce energy).
In the absence of this presumed aerosol cooling effect, climate models predict that the earth should warm at a much faster rate than has been observed.
A large cooling effect from aerosols was thus introduced in the early 1990s as a way to “fix” the climate models and bring them closer in line with the modest pace of observed warming. Despite that “fix,”climate models continue to overpredict the observed warming rate—which is bad enough news for climate models already.
Dr Nicolas Bellouin, Associate Professor of Climate Processes at the University of Reading. and his team shows that the anthropogenic cooling impact from clouds is much less than “assessed” by the U.N.’s Intergovernmental Panel on Climate Change (IPCC) and also much less than employed by climate models.
Less enhanced cloud cooling means that greenhouse gases have produced less warming than the climate models have determined.
Another way to put it is that this new finding implies that the earth’s climate sensitivity—how much the earth’s surface will warm from a doubling of the pre-industrial atmospheric carbon dioxide concentration—is much below that of the average climate model (3.2°C) and near the low end of the IPCC’s 1.5°C to 4.5°C assessed range.
This result comports with the concept of “lukewarming,” which we describe in an upcoming (August) hardcover book as “the new science that changes everything”
A study by Bjorn Stevens published in the journal of the American Meteorological Society last June came to the same conclusion.
These are all highly respected scientists who will have their reputations whipped by the left who want to control us.
The same Cato bloggers quoted above said that, if that study holds up, “it is the death blow to global warming hysteria.”
Somewhere Al Gore is crying. He was so hoping we were facing climate Armageddon.
John Pedestal recently boasted that Obama’s climate agenda can’t be stopped but it can if we vote Democrats out in November.
We knew it was vastly exaggerated and done deliberately when the climate gate scandal was revealed though the press and the leftists ignored it.
