"UK Scientists have produced further compelling evidence showing that modern-day climate change is not caused by changes in the Sun's activity.


This is the latest piece of evidence which at the very least puts the cosmic ray theory, developed by Danish scientist Henrik Svensmark at the Danish National Space Center (DNSC), under very heavy pressure.
Dr Svensmark's idea formed a centrepiece of the controversial documentary The Great Global Warming Swindle."

I would like to know why NASA is reporting that mars is also having a climate change, if the sun (which NASA has said is in an active period) has no impact on it.

Mars has a very different environment to Earth; radiation levels, gases, pressure - and very little historical evidence (compared to the immense amount we have from this planet). It is a fascinating and possibly useful comparison but hardly 'apples to apples' and we know so little it is impossible to judge - yet.

I agree that we DONT know enough about our climate change. I do however belive that it is not human led. There is a fosilized palm tree a few miles from where I am. It must have been more tropical at 6000 above sea level, in Colorado for it to have grown right?

The sun HAS to play a role somewhere, it is the brightest, and the hotest thing near by, the radiation certainly does enter our atmosphere (northern lights) it seems that the article was looking more at the effects of the sun on cloud formation than heat production.

Default Dr. James Hansen, NASA: Global Warming Caused by burning fossil fuels

You can read Dr. Hansen's website, where he has posted his articles about AGW. Every major scientific group in the world agrees that global climate change is caused by burning fossil fuels. I suggest you read Dr. Hansen's work. He has been studying climate change for 30 years. If we don't make changes in the next couple of years, our kids' futures are doomed. Wars over land and fresh water, ruined economies, droughts and famine.....all things we're leaving our grandkids:
www.

columbia.edu/~jeh1/

There's a huge gap between what is understood about global warming by the relevant scientific community and what is known about global warming by those who need to know: the public and policy-makers. We've had, in the past thirty years, one degree Fahrenheit of global warming. But there's another one degree Fahrenheit in the pipeline due to gases that are already in the atmosphere. And there's another one degree Fahrenheit in the pipeline because of the energy infrastructure now in place--for example, power plants and vehicles that we're not going to take off the road even if we decide that we're going to address this problem.

Besides those who deal in words and not equations, please show some well reasoned technical data which indicates precisely what it would take to immediately reduce the global temperature by one degree celsius in the immediate future by a man made solution.

I'm afraid that the technical realities coupled with the economic realities would indeed result in "Wars over land and fresh water, ruined economies, droughts and famine" .

Every group? I doubt that.

These scientific organizations agree that global climate change is most likely caused by humans burning fossil fuels:
American Association for the Advancement of Science,
(AAAS)
Intergovernmental Panel on Climate Change (IPCC)
(This report finds that human actions are "very likely" the cause of global warming, meaning a 90% or greater probability.)
U.S. National Research Council
American Meteorological Society
European Academy of Sciences and Arts
Royal Meteorological Society (UK)
World Meteorological Organization (WMO)
American Geophysical Union
American Institute of Physics
American Astronomical Society
American Physical Society
Federal Climate Change Science Program
National Center for Atmospheric Research
Stratigraphy Commission of the Geological Society of London
American Quaternary Association
Geological Society of America
American Chemical Society
Federation of American Scientists
Engineers Australia (The Institution of Engineers Australia)
Australian Meteorological and Oceanographic Society
Canadian Meteorological and Oceanographic Society
Canadian FoundatioEuropean Geosciences Union
European Geosciences Union
International Union of Geodesy and Geophysics
International Union of Geological Sciences
International Council for Science
European Science Foundation

This fossil-fuel-industry-funded organization disagrees:

How much money does the fossil fuel industry have to lose? Exxon Mobil made $40 billion last year. They have a noose around our necks and it's getting tighter.

How about if we try to be good stewards of this god-given planet and start to conserve energy?

On the other side of the coin...How much $ do the eco business have to gain? Yes it is a business and a very large one.

That would be interesting to know - do you have any figures?
