Decadal and longer changes in sunspot activity impacting warming and cooling cloud cover patterns are now being recognized as an important factor.

Don't worry about the problem of cooling either, because MojoPlay has seen fit to make the casing just wide enough so that it doesn't cover the cooling vents on the side of the console.

But when sun spot activity is low, a condition that can sometimes persist over decades and longer, the increased cosmic ray bombardment produces more cloud cover, hence cooling influences.

He says that tree cover is a good first step to keeping cooling costs down in the South.

The permits cover the discharge and disposal of radioactive waste and cooling water.

The Environment Agency permits cover the discharge and disposal of radioactive waste and cooling water and running of standby generators.

Less ice on rivers, lakes and the sea will lead to more evaporation, probably increasing cloud cover at mid-levels, which should have a cooling effect.

ECONOMIST: The science

Many students of climate change argue that, although the artificial release of greenhouse gases such as carbon dioxide works to raise the global temperature, particulate pollution should, by promoting cloud cover and thus reflecting solar energy back into space, have a compensating cooling effect.
