Global Warming? Science And History Say No

Francis T. Manns in todays' Post-Chronicle:

What is Global Warming? Throughout time the Earth's climate has varied. Since the base of the Pleistocene (1.8 M ya) there have been at least 30 glacial - interglacial cycles of 40,000 years to 100,000 years duration with interglacial periods warmer than now between them.

(...) Realistically, the planet is not warming in the dramatic manner the alarmists claim.

The sun heats the earth; cosmic radiation cools it. Do some scientific reading and let Al Gore’s PG rated scare dry up and blow away. He’s simply an irrelevant opportunistic manipulative politician. His only followers are sheep.

There's a link to Dr. Mann's excellent powerpoint presentation Global Warming and Science, also available under Good Stuff in my sidebar at right.
