Sometimes I wish I could be a climate skeptic. It would be such a relief to remain optimistic about the future of the world -- despite all the evidence to the contrary. On Friday the world's top scientists released their latest gloomy assessment of global warming and the message was clear: we need to find a way to stop burning fossil fuels or risk imperilling the planet.
Most North Americans know that human-caused global warming is real, even if political leaders don't always reflect or act on that knowledge. According to a recent poll, only two per cent of Canadians reject the overwhelming scientific evidence that Earth is warming at alarming rates -- a figure that may seem surprising given the volume of nonsense deniers.
