Scientist who was fmr. Greenpeace member says ‘no proof’ CO2 is driving global temps!

From Canada Free Press, October 15, 2008

Another Dissenter: Finnish Scientist who was former Greenpeace member says ‘no proof’ CO2 is driving global temps!

Dr. Jarl R. Ahlbeck is lecturer of environmental technology and a chemical engineer at Abo Akademi University in Finland who has authored 200 scientific publications and hold four patents. Ahlbeck is a former member of Greenpeace and the Finnish socialist party DFFF. Bio here

No significant global warming since 1995

by Jarl R. Ahlbeck The writer is D.Sc. and lecturer at Abo Akademi University, Finland

The recovery of the earth’s climate from the little ice age started about 200 years ago, but the concentration of the atmospheric carbon dioxide started to increase significantly as late as in the 1950s, probably due to rapidly increased burning of fossil fuels.

The climate recovery is still an ongoing process today. A natural warming rate of roughly 0.5 deg C /100 years has been the baseline for more than 100 years, but both short (a few years) and long (20 years) fluctuations around the baseline have occurred for natural but highly speculative reasons, for example a rapid warming in the 1930s followed by a cooling period, and recently again warming until about 1998.

According to the UK climate panel IPCC, this last warming period has been forced by increased carbon dioxide concentration in the atmosphere. There is however no proof of that and the theory of how carbon dioxide influences the global mean temperature is complicated and unreliable. And if the global temperature again starts to increase slower than the natural long-term trend of 0.5 deg C/100 years, or even starts to cool, we can be quite certain that the recent faster warming trends have been natural too.

What is a Greenpeace member? Someone who gave a few bucks to Greenpeace once upon a time? How does that make them more credible than, say, the Royal Society, NASA and the IPCC?

Something that is not looked at is the amount of CO2 being re-released from the Polar Ice Caps and melting glaciers since 1950s that probably belonged to our forefathers, fires, etc. If you see how much has melted in the time mentioned, it is a term paper for some master degree thesis.,
