A new book will be released next week making the case that global warming is likely much more caused by cosmic rays than any human activity. As reported by the Daily Telegraph (emphasis mine throughout):
Scientists say that cosmic rays from outer space play a far greater role in changing the Earth's climate than global warming experts previously thought.
In a book, to be published this week, they claim that fluctuations in the number of cosmic rays hitting the atmosphere directly alter the amount of cloud covering the planet.
The article continued:
Henrik Svensmark, a weather scientist at the Danish National Space Centre who led the team behind the research, believes that the planet is experiencing a natural period of low cloud cover due to fewer cosmic rays entering the atmosphere.
This, he says, is responsible for much of the global warming we are experiencing.
He claims carbon dioxide emissions due to human activity are having a smaller impact on climate change than scientists think. If he is correct, it could mean that mankind has more time to reduce our effect on the climate.
The controversial theory comes one week after 2,500 scientists who make up the United Nations International Panel on Climate Change published their fourth report stating that human carbon dioxide emissions would cause temperature rises of up to 4.5 C by the end of the century.Mr Svensmark claims that the calculations used to make this prediction largely overlooked the effect of cosmic rays on cloud cover and the temperature rise due to human activity may be much smaller.
He said: "It was long thought that clouds were caused by climate change, but now we see that climate change is driven by clouds.
"This has not been taken into account in the models used to work out the effect carbon dioxide has had.
"We may see CO2 is responsible for much less warming than we thought and if this is the case the predictions of warming due to human activity will need to be adjusted."
Fascinating stuff, yes? What’s that do for all this absurd consensus talk? And, the article went on to address how a group of scientists will be convening in Switzerland soon to further test his theories:
Mr Svensmark last week published the first experimental evidence from five years' research on the influence that cosmic rays have on cloud production in the Proceedings of the Royal Society Journal A: Mathematical, Physical and Engineering Sciences. This week he will also publish a fuller account of his work in a book entitled The Chilling Stars: A New Theory of Climate Change.
A team of more than 60 scientists from around the world are preparing to conduct a large-scale experiment using a particle accelerator in Geneva, Switzerland, to replicate the effect of cosmic rays hitting the atmosphere.
They hope this will prove whether this deep space radiation is responsible for changing cloud cover. If so, it could force climate scientists to re-evaluate their ideas about how global warming occurs.
Mr Svensmark's results show that the rays produce electrically charged particles when they hit the atmosphere. He said: "These particles attract water molecules from the air and cause them to clump together until they condense into clouds."
Mr Svensmark claims that the number of cosmic rays hitting the Earth changes with the magnetic activity around the Sun. During high periods of activity, fewer cosmic rays hit the Earth and so there are less clouds formed, resulting in warming.
Low activity causes more clouds and cools the Earth.
He said: "Evidence from ice cores show this happening long into the past. We have the highest solar activity we have had in at least 1,000 years.
"Humans are having an effect on climate change, but by not including the cosmic ray effect in models it means the results are inaccurate.The size of man's impact may be much smaller and so the man-made change is happening slower than predicted."
Furthermore, the article demonstrated that far from being the consensus surrounding this issue that the U.N., Al Gore, or liberal media representatives claim, there is great debate concerning this matter:
Some climate change experts have dismissed the claims as "tenuous".
Giles Harrison, a cloud specialist at Reading University said that he had carried out research on cosmic rays and their effect on clouds, but believed the impact on climate is much smaller than Mr Svensmark claims.
Mr Harrison said: "I have been looking at cloud data going back 50 years over the UK and found there was a small relationship with cosmic rays. It looks like it creates some additional variability in a natural climate system but this is small."
But there is a growing number of scientists who believe that the effect may be genuine.
Among them is Prof Bob Bingham, a clouds expert from the Central Laboratory of the Research Councils in Rutherford.
He said: "It is a relatively new idea, but there is some evidence there for this effect on clouds."
The point is, folks, that there is no consensus. Not even close. And, before America starts doing anything that might have a negative impact on our economy or our ability to compete globally, we ought to have all the facts – not just those supplied by folks looking to turn this into a political victory.
