Global Warming?

There is a growing list in the scientific community questioning the 
causes of global warming. It's a separate issue from the causes of 
and need to correct man made pollution. Many of them question the 
reliability of modeling global climate, others point to increased 
solar radiation.

Reid Bryson, emeritus professor of Atmospheric and Oceanic Sciences, 
University of Wisconsin-Madison: "It's absurd. Of course it's going 
up. It has gone up since the early 1800s, before the Industrial 
Revolution, because we're coming out of the Little Ice Age, not 
because we're putting more carbon dioxide into the air."[18] 

Ian Clark, hydrogeologist, professor, Department of Earth Sciences, 
University of Ottawa: "That portion of the scientific community that 
attributes climate warming to CO2 relies on the hypothesis that 
increasing CO2, which is in fact a minor greenhouse gas, triggers a 
much larger water vapour response to warm the atmosphere. This 
mechanism has never been tested scientifically beyond the 
mathematical models that predict extensive warming, and are 
confounded by the complexity of cloud formation - which has a cooling 
effect. ... We know that [the sun] was responsible for climate change 
in the past, and so is clearly going to play the lead role in present 
and future climate change. And interestingly... solar activity has 
recently begun a downward cycle."
