Good Morning, Sunshine! Thanks for the Heat!!

Actually printed in the MSM:

Climate changes such as global warming may be due to changes in the sun rather than to the release of greenhouse gases on Earth.

The sun provides all the energy that drives our climate, but it is not the constant star it might seem.

Careful studies over the last 20 years show that its overall brightness and energy output increases slightly as sunspot activity rises to the peak of its 11-year cycle.
And individual cycles can be more or less active.

The sun is currently at its most active for 300 years.

That, say scientists in Philadelphia, could be a more significant cause of global warming than the emissions of greenhouse gases that are most often blamed.

The researchers point out that much of the half-a-degree rise in global temperature over the last 120 years occurred before 1940 - earlier than the biggest rise in greenhouse gas emissions.

Using ancient tree rings, they show that 17 out of 19 warm spells in the last 10,000 years coincided with peaks in solar activity.

Back to the Threat of Cooling...
