global warming deniers

What's outlandish is attributing massive changes in climate to increases in carbon dioxide, a trace gas that represents so miniscule a fraction of our atmosphere that it must be measured in parts per million. Established science had historically held natural forces to drive climate.
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.
The global warming deniers are at it again, and it is high time that the environmental movement launched a campaign to expose them. We may not see effective action concerning climate change until many more business executives are convinced the changes are hurting both business and society.
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.
