Why CO2 Rise doesn't Threaten Temperature
“CO2 is not currently a major climate driver. Even if CO2 concentration doubles or triples, the effect on temperature would be minimal. The relationship between temperature and CO2 is like painting a window black to block sunlight. The first coat blocks most of the light. Second and third coats reduce very little more.
Current CO2 levels are like the first coat of black paint. Computer climate models get around this by assuming that a highly questionable hypothesis is correct, namely that small increases in temperature due to large CO2 rises cause more evaporation and the subsequently higher concentration of water vapor (the major greenhouse gas) in the atmosphere will cause further temperature rise. More likely, the resultant increased cloud cover will drive temperatures down.”
--Climatologist Dr Tim Ball, Canada's National Post
"There's a different side to what is causing climate change. I think too much emphasis has been put on CO2. I do not believe CO2 is a pollutant. I'm made of CO2, you're made of CO2 ... the ocean is a reservoir of CO2."
--Meteorologist David Aldrich Meteorologist, Philadelphia City Paper

Tim Ball has absolutely no credibility in the scientific community. If he has scientific points to make, let him make them in the peer-reviewed literature. Until then, his comments are worthless.
Interesting comment, Tom. From SourceWatch: "Dr. Ball is a renowned environmental consultant and former [retired] professor of climatology at the University of Winnipeg. Dr. Ball has served on many local and national committees and as Chair of Provincial boards on water management, environmental issues and sustainable development. Dr. Ball has given over 600 public talks over the last decade on science and the environment. He is the co-author of the book Eighteenth Century Naturalists of Hudson Bay (2004 - McGill/Queens University Press) with Dr. Stuart Houston, one of the World's leading authorities on arctic birds," his NRSP profile states (accessed November 21, 2006).
1. What are your scientific credentials to make such a judgment about Tim Ball? 2. What, if any, other facts are you using to make such a statement?
