Climate Change Info from an IPCC Scientist

[TexasBob]

I have been a reviewer of the last two IPCC reports, one of the several thousand scientists who purportedly are supporters of the IPCC view that humans control global temperature. Nothing could be further from the truth. Many of us try to bring better and more current science to the IPCC, but we usually fail. Recently we found out why. The whistleblower release of e-mails and files from the Climate Research Unit at East Anglia University has demonstrated scientific malfeasance and a sickening violation of scientific ethics.-- Lee C. Gerhard, IPCC Expert Reviewer

Interesting details at ICECAP

Some samples:

• Carbon dioxide concentration has been continually rising for nearly 100 years. It continues to rise, but carbon dioxide concentrations at present are near the lowest in geologic history.
• The greenhouse effect of carbon dioxide logarithmically declines with increasing concentration. At present levels, any additional carbon dioxide can have very little effect.
• During the last 100 years, temperature has both risen and fallen, including the present cooling. All the changes in temperature of the last 100 years are in normal historic ranges, both in absolute value and, most importantly, rate of change.
• Voluminous historic records demonstrate the Medieval Climate Optimum (MCO) was real and that the “hockey stick” graphic that attempted to deny that fact was at best bad science. The MCO was considerably warmer than the end of the 20th century.
• Polar bears have survived and thrived over periods of extreme cold and extreme warmth over hundreds of thousands of years - extremes far in excess of modern temperature changes.
• The 2009 minimum Arctic ice extent was significantly larger than the previous two years. The 2009 Antarctic maximum ice extent was significantly above the 30-year average. There are only 30 years of records.
