Hurricanes that are going over warm water intensify, and hurricanes in a global warming earth going over ever more warming water, will intensify more.
Yet the overall variation is tiny, just 0.1% of the sun's total output, which seems insufficient to be the cause of a warming Earth.
They argue that the shorter studies have not taken into account that the warming Earth is seeing today could have happened before naturally -- thousands of years ago.
The IPCC Panel's near-consensus was that human activity is having some discernible impact on climate, and that by 2100, a warming earth could result in more frequent storms and droughts, sea level rise of up to three feet, and up to six degrees F. in temperature rise.

Only 28% of respondents 65 and over thought there was solid evidence the earth was warming because of human activity, versus 42% overall.

What I do know is that even if the earth is warming, and even if it's due to human activities, any significant lowering of emissions will be too costly, too little and too late.
But if Svensmark was correct, it would mean that periods of high solar output should coincide with reduced cloud formation (due to reduced cosmic ray incidence), which in turn would have a warming effect on the Earth, since less sunlight would be reflected back into space by clouds.
And a scientist claims he has a way to save the Earth from global warming, for a while at least.
He is locking horns with the industry and telling it to put on its collective thinking cap and to recognize that the earth is unnaturally warming.

Many industrialized nations are trying to use less coal, oil and natural gas to lower carbon dioxide levels, which is warming the atmosphere and changing the Earth's climate.
That points to the biggest fear: warming may trigger irreversible changes that transform the earth into a largely uninhabitable environment.
Pinatubo provided the best model in at least a century to help us understand what might happen if humans attempted to ameliorate global warming by deliberately altering the climate of the earth.
Ken Caldeira of Stanford University, another of the authors, reckons that it may be feasible to place sulphates in the stratosphere near the poles and thus cool the Earth in a place where global warming manifests itself most strongly, though that would scarcely please the Russians and the Canadians.
