text: Thank you for your response. I have dealt with two issues. 1. The notion that carbon taxes on Canadians will make any difference to the problem, or would need to be prohibitively large to make a difference and that Canadians be made aware of this information from their elected representatives so that they can make rational choices. 2. That science is rarely settled. That, as more information comes in we need to look at it and assess what it means for the bigger picture. The most recent research by some prominent climate scientists says that the computer predictive models used by the IPCC and others overestimated temperatures for the past 20 years. To me that means they made errors with the inputs and that there were flaws in their methodology. What troubles me is that for raising these issues some people use the term denier, which is a word with almost religious connotations and is meant in most cases to be insulting. I was sorry to see you use it as it doesn't fit with your moniker.
