Global Warming - And cloud cover
This article describes a credible study that disputes the "caused by humans" hysteria...
At FoxNews.com, Steven Milloy reports:
"That is, cloud cover changes over a 5-year period can have 85 percent of the temperature effect on the Earth that has been claimed to have been caused by nearly 200 years of manmade carbon dioxide emissions. The temperature effects of cloud cover during the 20th century could be as much as 7 times greater than the alleged temperature effect of 200 years worth of additional carbon dioxide and several times greater than that of all additional greenhouse gases combined.
So although it has been taken for granted by global warming alarmists that human activity has caused the climate to warm, Svensmark’s study strongly challenges this assumption.
Given that the cosmic ray effect described by Svensmark would be more than sufficient to account for the net estimated temperature change since the Industrial Revolution, the key question becomes: Has human activity actually warmed, cooled or had no net impact on the planet?"
