In the recent past, as I began once again to explore the evidence supporting the theory of Global Warming (caused solely by human activity), I was willing to grant a rise in CO2 from 1850 to 2005 from 280 to 350 ppb. I am no longer willing to do that. Here is the reason--an article by Polish scientist Zbigniew Jaworowski which points out a lot of problems with establishing a baseline of pre-industrial CO2 in the atmosphere. We obviously did not have CO2 sniffers around in 1850 (the Mauna Loa observatory, whose data is the bedrock uderlying the central, Warmie belief, only began sniffing CO2 in 1958--although, to be fair, it does show an increase in CO2 from 315 to 377 ppb between 1960 and 2004). Absent instrument readings, we have to rely on other sources to establish how much CO2 was in the air of the past. We have to rely on air 'trapped in amber' (not really--that was a metaphor) and the first choice of scientists has been ice cores drilled out of deep ice around the world. Unfortunately, ice cores are useless for what the air contained before a certain date (because deep ice has no bubbles--the pressure squeezes them out), and ice cores often are contaminated by extraction and processing, and the data shown from ice cores are often fudged by the scientists and the results published are sometimes just plain fraudulent.

Zbig says global CO2 concentration in 1870 was probably just as high as it was in 1970. Yet the Warmies say average temperature globally increased about a whole degree Fahrenheit during that time. If the CO2 was the same at the beginning and end of the period during which the temperature rose, CO2 concentration could not have caused it. QED. Yet CO2 concentration increasing as temperatures rise is the sine qua non of Warmie dogma.

And then there's this data from Lawrence Hecht. If he's right here, the growing consensus the Warmies crow about is becoming an increasingly tattered tissue of lies.

Highlights:

- Since 1980, there has been an advance of more than 55% of the 625 mountain glaciers under observation by the World Glacier Monitoring group in Zurich. (From 1926 to 1960, some 70-95% of these glaciers were in retreat.)
- A comparison of the U.S. Department of Agriculture's 1965 and 1990 Plant Hardiness Zone Maps, shows a southward change of one zone, or 10°F, between 1965 and 1990.
- Careful measurements of the oxygen isotope ratios in German oaks, which are rigorously calibrated to temperature data, show a 1°C temperature decline from 1350 to 1800 (the lowpoint of the Little Ice Age). Temperature thereafter increased by 1°C from 1800 to 1930, and has been declining since then.
- From weather stations in the Alps, and in the Nordic countries, we find the temperature decline since 1930 is also 1°C.
- Satellite measurements have shown growth in the height and breadth of the huge Greenland ice sheet, the largest in the Northern Hemisphere.

The statement that there is no dispute about Global Warming (caused solely by human activity) is bunk in the casual observers and a lie in the mouths of those who know the science.
