An interesting point:

Wildfires are a major source of these gasses. The area affected each year by these fires has approximately doubled in the last ten years. Contributing factors are hotter, dryer weather, which is made worse by the amount of greenhouse gasses released by these fires. When you track CO2 sources, the clearing of the Brazillian rainforest becomes as significant as industrial activity elsewhere.



Here in Alberta, there's a high level of paranoia about misguided policies (like a carbon tax) that might be imposed by our eastern-based Federal Government. That's a sad state of affairs, given that Alberta has been leading the way in terms of addressing pollution and energy efficiency concerns. The net increase in our country has been due to activity in the industrial centres in Ontario and Quebec. Ironically, these are the provinces pushing for carbon taxes that would cripple Alberta's energy industries. I suspect that would severely strain relations between Canada and the US, given that Canada (Alberta) is now supplying more of America's oil and natural gas than any other source.
