Cosmic Ray Attack

I love this whole glowbull warming crap. It just gets more and more interesting every day. Today we find out that cosmic rays seem to be responsible for part of the damage. The science makes sense to me but I would like to see the results of the experiments they plan on conducting in Switzerland.

The cycles of heating and cooling seem to coincide with high solar activity and other factors that could influence the amount of cosmic rays hitting our atmosphere. Factor in fluctuations in the Van-Allen Belt and this team of scientists could be on to something. Then add in the fact there are fewer pollutants in the air nowadays thanks to clean air acts and what you have is a lot of clear skies over our heads. Them cosmic rays are pounding us! HELP! RUN AWAY! RUN AWAY!

Cosmic Rays Blamed For Global Warming
_{LONDON (TELEGRAPH-UK) - 1:08am GMT 11/02/2007}

Man-made climate change may be happening at a far slower rate than has been claimed, according to controversial new research. 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. High levels of cloud cover blankets the Earth and reflects radiated heat from the Sun back out into space, causing the planet to cool.

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.”

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.

Not that very many people ever read this far down, but this blog was the creation of Allan Kelly and his friend Vilmar. Vilmar moved on to his own blog some time ago, and Allan ran this place alone until his sudden and unexpected death partway through 2006. We all miss him. A lot. Even though he is gone this site will always still be more than a little bit his. We who are left to carry on the BMEWS tradition owe him a great debt of gratitude, and we hope to be able to pay that back by following his last advice to us all:

1. Keep a firm grasp of Right and Wrong
2. Stay involved with government on every level and don't let those bastards get away with a thing
3. Use every legal means to defend yourself in the event of real internal trouble, and, most importantly:
4. Keep talking to each other, whether here or elsewhere

It's been a long strange trip without you Skipper, but thanks for pointing us in the right direction and giving us a swift kick in the behind to get us going. Keep lookin' down on us, will ya? Thanks.
