We've discussed this issue. I discussed it with my colleague, Professor Stewart. We are scientists, and we wish to convey the urgency of doing something on climate change. We believe any measure that is effective in the short and long term is very needed, but whether we go to cap and trade and the politics of posturing for Copenhagen is not something we feel competent to deal with, nor do we think we should, as scientists. We simply wish to convey to people that this is a very urgent issue and that Canada should take rapid measures to reduce greenhouse gas emissions by any and all methods that will be effective.
