Global Warming, a Cosmic Cause
I heard about this a little while ago and wanted to give it space to be read and thought about. Ok, not that the masses are hanging on my every written word, but.. It is still important to incorporate this very important research as the finger pointing and consequent problem solving has to shift in a bit of different direction. Not only that, people with opposing viewpoints have been so polarized, that this bit of news can upset plenty of people on either side of the coin and either have them negate any sustainable practices (what's the use?) or react with equal force to save it even more. Who knows.. Anyhow.. here goes, excerpt time:
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, Danish National Space Centre
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.

So now what?
