Cosmic rays may solve global warming problem

Cosmic events could help soften the impact of global warming by triggering cloud formations, suggests research published yesterday.
A team of Danish scientists concluded in the Proceedings of the Royal Society that making clouds is plausible, using the Sun's magnetic field.
The Sun has been at its strongest for more than 60 years and a period of high solar activity could be approaching its end. "This would produce a cooling effect that could counter part of the global warming predicted for the next century," said Dr Jens Olaf Pedersen, of the Danish National Space Centre.
advertisement When cosmic rays, high energy particles from distant exploding stars, fall to Earth they knock electrons off atoms in the atmosphere, making them electrically charged, or ionized. The ions form clusters of molecules that can grow into droplets forming low-lying clouds.
More cosmic rays would produce clouds that would increase the rate at which sunlight was reflected away from the planet and so cool it.
Hmmmm. Sun hotter = Earth hotter. Problem solved, it's a natural cycle.
The first rule of life: most problems solve themselves if you just get out of the way and let them.
Of course, it's very easy for a problem to fix itself when it doesn't exist.
"expert": no, no, this finding doesn't agree with current Global Warming dogma and must therefore be wrong.
Quit your interference of the ALbore candidacy.
The Earth moves away from the Sun something like a half inch a year. Eventually Earth will be covered in ice.
I sense a Fantastic Four reference coming soon.
... Oh, wait.
1. Global warming is true.
2. We still can't find evidence of it.
3. We must find a way to explain this lack of evidence.
4. Cosmic rays. Create a theory involving cosmic rays.
A less active sun creates more cosmic rays, which create more clouds, which deflect heat? I am getting the dominos right here? The squib is rather delphic. One would think a more active sun would create more cosmic rays, not less.
How much is big oil paying the sun?????
There is evidence of global warming in the northern hemisphere. The rest is rather more speculative.
Darn I was too slow
One of the most often repeated ADM Rickover stories goes like this: Rickover was visiting the Idaho Falls Prototype, and a couple of enterprising students called his hotel room just before dawn and said, "Request permission to light off the sun, Admiral!" To which Rickover replied, "What is the lube oil temperature?" The students gave the correct answer for the minimum lube oil temperature for the main turbines, and Rickover said: "Permission granted, light off the sun!"
Bump for tomorrow. Sun is way hotter than just for 60 years.
Wrong answer, cancel his grant.

So, basically there's a ton of variables and the scientists are all talking out of their hats when they try to predict the weather. Ok, I'll buy that.
Believing that they had the experience and intellect to grasp what is perhaps the most difficult scientific puzzle facing mankind: climate and all of its permutations, cycles and feedback loops.
A lot more relevant than the "big bang".
Guess the little boys didn't quite have the mental horsepower that they thought they did...
blam: Thanks for the report.
If it is true that the Sun has "brightened" during the past 60 years, then the "Theory of Anthropogenic Global Warming" has lost still more of its "credibility", has it not?
ERF: "Ping"...
...and a follow-up question:
Do you acknowledge that the Medieval Warming Period and the Little Ice Age did, in fact, occur?
Of course they occurred; at least an overwhelming amount of evidence points to the fact that they did.
Of course the warming and cooling experienced during those periods was between .5 and 1.5 degrees celcius. It also changed over a 3-400 year period. We have experienced the 1 degree celcius change in less than a century and are looking at up to 3 degrees over the next. As I have previusly mentioned, it might just be terrible timing that we are combining man-made influences with natural cycles to produce a much greater than natural change.
And this from a Danish source:
"An essential role for remote stars in everyday weather on Earth has been revealed by an experiment at the Danish National Space Center in Copenhagen."
"It is already well-established that when cosmic rays, which are high-speed atomic particles originating in exploded stars far away in the Milky Way, penetrate Earth’s atmosphere they produce substantial amounts of ions and release free electrons. Now, results from the Danish experiment show that the released electrons significantly promote the formation of building blocks for cloud condensation nuclei on which water vapour condenses to make clouds."

This makes a lot of sense when we consider what can be seen in a 'cloud chamber' experiment.
Check out post 22 and in particular this paragraph in the source link.
"Interestingly, during the 20th Century, the Sun’s magnetic field which shields Earth from cosmic rays more than doubled, thereby reducing the average influx of cosmic rays. The resulting reduction in cloudiness, especially of low-altitude clouds, may be a significant factor in the global warming Earth has undergone during the last century. However, until now, there has been no experimental evidence of how the causal mechanism linking cosmic rays and cloud formation may work."
