Here is an interesting article on an alternative theory for global warming/climate change:

A team at the Danish National Space Center has discovered how cosmic rays from exploding stars can help to make clouds in the atmosphere. The results support the theory that cosmic rays influence Earth's climate.

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.

Hence, a causal mechanism by which cosmic rays can facilitate the production of clouds in Earth's atmosphere has been experimentally identified for the first time.

The Danish team officially announced their discovery on Wednesday in Proceedings of the Royal Society A, published by the Royal Society, the British national academy of science.

It is known that low-altitude clouds have an overall cooling effect on the Earth's surface. Hence, variations in cloud cover caused by cosmic rays can change the surface temperature. The existence of such a cosmic connection to Earth's climate might thus help to explain past and present variations in Earth's climate.

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.

...Svendmark hesitates, however, blaming global warming solely on cosmic rays.

'I'm saying that the sun has an effect. But I'm also saying it's uncertain how much global warming has to do with the sun and how much is caused by carbon dioxide in the atmosphere.'

Svendmark said it is not possible yet to know for sure what the correlation is between rising temperatures and the new information.

'The greenhouse effect must play some role. But those who are absolutely certain that the rise in temperatures is due solely to carbon dioxide have no scientific justification. It's pure guesswork.'

--As a note, I still believe in conservation, reducing/elimination of pollution, and working towards long term substable energy production and agriculture.
