"Skeptics Help Us Search for Truth"

Article by Dennis Avery here.

Excerpts:

When global warming alarmists condemn skeptics as deniers, it is an unscientific and socially dangerous characterization. Skeptics are not the enemy. On the contrary, they are crucial to science because they help us search for truth.

Scientific theories exist to be verified or proven false. Thomas Huxley, a famous nineteenth-century English biologist, explained, "Skepticism is the highest of duties; blind faith the one unpardonable sin."

...Yet there are those inconvenient facts: Chinese researchers recently examined their ancient historic records, which go back farther in China than in any other society. They found evidence of a warm period from the years 1 to about 240 AD (known as the Roman Warming); a cold period (the Dark Ages) from 240 to 800 AD; a warming (the Medieval Optimum) from 800 to 1400; and the Little Ice Age from 1400 to about 1920.

From this evidence, the Chinese researchers concluded China's warmest period during the past 2000 years occurred around 100 AD. (See Bao Yang, et al., "General Characteristics of Temperature Variation in China During the Last Two Millennia," Geophysical Research Letters, 10 (2002): 1029/2001GLO014485.) This aligns with Roman records of growing wine grapes in Britain during their occupation of that island in the first century--even though Britain was unable to grow wine grapes from 1300 to 1950 because of too-cold temperatures.

If China was warmer during the first century than today, what's so remarkable about today's warming?

Perhaps the most powerful evidence of all is the strong correlation between sunspot records and the Earth's temperatures during the "thermometer years" since 1860. Henrik Svensmark of the Danish Space Research Institute found a 95-percent correlation between the sunspot numbers and the lagged record of the Earth's sea-surface temperatures.

The reality is, since 1998 CO2 levels have continued to soar while the Earth's temperatures have held stable.

The climate models are not evidence; they are guesses. The fact that they tend to agree with each other says more about discussions among the modelers than about the accuracy of the models.
