This paper went through three rounds of peer-review. You alarmists don't like it because it does not support your paradigm. The temperature gages we use now are at best +/- 0.5 degrees C in accuracy and we are quibling over 0.01 degree differences. Second, Klaus Hager 44-year veteran German meteorologist placed dozens of older mercury thermometers side-by-side with modern instruments used today all over Germany. Over an 8 and half year study, he found on average that the newer thermometers showed temperatures 0.93 deg C higher than the old mercury types. Germany began replacing their mercury thermometers in 1985 at all 2000 weather stations and completed the task by 2000. “Warming” in Germany began in 1986, stopped in 2000 and has been flat since 2000 and also was flat prior to 1985. Coincidence?
Here is another problem with 'models.'
Physicist Howard Hayden's one-letter disproof of global warming claims [pre-Climategate]Dear Administrator Jackson:
I write in regard to the Proposed Endangerment and Cause or Contribute Findings for Greenhouse Gases Under Section 202(a) of the Clean Air Act, Proposed Rule, 74 Fed. Reg. 18,886 (Apr. 24, 2009), the so-called "Endangerment Finding."
It has been often said that the "science is settled" on the issue of CO2 and climate. Let me put this claim to rest with a simple one-letter proof that it is false.
The letter is s, the one that changes model into models. If the science were settled, there would be precisely one model, and it would be in agreement with measurements.
Alternatively, one may ask which one of the twenty-some models settled the science so that all the rest could be discarded along with the research funds that have kept those models alive.
We can take this further. Not a single climate model predicted the current cooling phase. If the science were settled, the model (singular) would have predicted it.
