But from the least publicized views of certain "heretics", the notion that CO2 caused global warming has been thought of as fundamentally flawed. Where Al Gore contends CO2 as the driver of global warming, these "heretics" contend otherwise.
In a video posted at YouTube, Al Gore was pitted against some of the climatologists who hold views opposite to Al Gore's. Here's what they say:
Prof. Ian Clark (Dept. of Earth Sciences, University of Ottawa): If we look at climate from the geological timeframe, we would never suspect CO2 is a major climate driver.
We can't say that CO2 would drive climate. It certainly never did in the past.
Piers Corbyn (Climate Forecaster, Weather Action): None of the major climate changes in the last thousand years can be explained by CO2.
Prof. Patrick Michaels (IPCC & Dept. of Environmental Science, University of Virginia): Anyone who goes around and says that CO2 is responsible for most of the warming of 2oth century hasn't looked at the basic numbers.

[/caption]In the past hundred fifty years, the temperature has risen just over half of degrees celsius. But the strange thing is most of that lies in the early decades of the 20th century--between 1905 and 1940 when industrial production was still...on its mold. At 1940, as industry expanded, for some reason, the world cooled.
Prof. Syun-Ichi Akasofu (Director, International Arctic Research Center): CO2 began to increase exponentially in about 1940. But temperature actually began to decrease in 1940 and continue to about 1975...When the CO2 is increasing rapidly and yet the temperature is decreasing, then we can not say that CO2 and temperature go together.
Dr. Tim Ball (Former Professor of Climatology, University of Winnipeg): Temperature went up significantly up to 1940 when human production of CO2 was relatively low. And then in the post-war years when industry and the whole economies of the world really got going and human production of CO2 just soared, the global temperature was going down. In other words, the facts didn't fit the theory (CO2 caused global warming).
There have now been several major ice core surveys. Every one of them shows the same thing: the temperature rises or falls, then after a few hundred years CO2 follows.
Dr. Tim Ball (Former Professor of Climatology, University of Winnipeg): The ice-cold record goes to the very heart of the problem we have here. It said, if the CO2 increases in the atmosphere, as a greenhouse gas, then the temperature will go up. But the ice core record shows exactly the opposite. So the fundamental assumption--the most fundamental assumption of the whole theory of climate change to the humans--is shown to be wrong.
As it said towards the end of the video, THEY DEBATE, YOU DECIDE.

ReplyDeleteNote NASA has changed their data and specifically now list 1934 as the warmest year. This conflicts with the earlier charts shown above. The tough part is the data from NASA, NOAA, and IPCC continue to change as scientist review the specifics.
ReplyDeleteSolar Chaos,
ReplyDeleteThanks for taking pains in writing your response to this blog entry.
Even if NASA had listed 1934 as the warmest years in years’ past, the main contention of the “heretics”—as I call them—is that, as shown in the 1st and 2nd charts, while there was a significant increase in CO2 during the industrial period, the global temperature cooled.
I would be glad if you will be able to provide the chart which listed 1934 as the warmest year.
