Man-Caused Global Warming Myth

Mr. George Bush of The Sea Ranch, natural climate change denier, chose a cartoon as his response to the science studies I include in my letters. From his description, it wasn’t a particularly clever cartoon. It’s amazing how the myth of the ostrich hiding its head in the sand has been around since Pliny the Elder (AD 23-79, who said it was in a bush, not sand), just as the anthropogenic global warming myth persists even after over 15 years of flat global temperatures, no accelerating sea level increase, and numerous reports of previous warmer periods.

NASA, with James Hansen famously leading its climate alarmism, just released a study of warming in the Arctic during the past century. According to a graph published on the NASA Earth Observatory site, Arctic temperatures were warmer in the 1930's than now. In addition, the graph shows the Arctic warmed 1.6C over the 19-year period from 1918-1937 at a rate of 0.84C/decade, 75% faster than the 0.48C/decade from 1980-2000. Between these two warming periods, Arctic temperatures dropped as CO2 increased. Thus, alarmist claims that recent Arctic warming is unprecedented or accelerating are bogus.

At the European Geosciences Union meeting, Authors Steirou and Koutsoyiannis, reported global warming over the past century was only about one-half [0.42°C] of that claimed by the United Nations IPCC [0.7-0.8°C].

A paper in the Palaeogeography, Palaeoclimatology, Palaeoecology journal finds that the Medieval Warming Period “was warmer than the late 20th century by ~1°C.” The paper adds to the peer-reviewed publications of over 1000 scientists in the Medieval Warm Period Project showing that the global Medieval Warming Period was warmer than the current warming period.

I’m pleased Mr. Bush apparently has accepted the debate offer I’ve had open for over three years. It’s about time.
