Global Warming - Sticks and Stones

I thank Mr. Lippman for his letter (Devious Dunce, ICO, April 9, 2010). It brought back fond memories of bygone days at Point Arena Elementary when we childishly taunted one another on the playground. Although equally tasteless, our taunts were far more clever and creative than Mr. Lippman’s.

Richard Feynman never mentioned global warming in his 1974 Caltech commencement address because then the world was preoccupied with another “Cargo Cult Science” candidate, global cooling. He didn’t mention cooling either, or many other worthy nominees; he left us to apply his concept as circumstances dictate.

Mr. Lippman pictured me reading without comprehension, but I will be kinder. I picture him accepting my offer to debate, and attempting to clothe his arguments in science rather than name calling.

Believers in anthropogenic global warming argue that current warming is unprecedented. The gist of my counter-argument is that numerous studies show warming was greater during the Medieval Warm Period (800 to 1300AD), and that it was even warmer during the Holocene Climate Optimum 9,000 to 5,000 years ago. These studies will show that warming during those periods was global and persistent, was reflected in ice cores, lake and ocean sediments, in the distribution of plants by latitude and elevations, and evidence from human settlements and historical records.

Arrayed against this record of natural climate changes going back over 11,000 years to the end of the Ice Age, the alleged evidence of man-caused global warming spans 60 years when global temperatures both rose and fell while atmospheric carbon dioxide increased. Now the “Climategate” e-mails show that alarmist scientists had to “hide the decline,” admit that the Medieval Warm Period was as warm or warmer, and that it is a “travesty” that their computer models can’t explain recent cooling.

May the best science win!
