No evidence of increasing droughts, floods, hurricanes and wildfires, despite activist claims

Extreme Weather and Climate Change

  • Assertions are made claiming that weather extremes are increasing in frequency and severity, spurred on by humanity’s greenhouse gas emissions.
  • Based on such assertions, governments are enacting ever more restrictive regulations on Canadian consumers of energy products, and especially Canada’s energy sector. These regulations impose significant costs on the Canadian economy, and can exert downward pressure on Canadian’s standard of living.
  • According to the UN IPCC, evidence does suggest that some types of extreme weather have become more extreme, particularly those relating to temperature trends.
  • However, many types of extreme weather show no signs of increasing and in some cases are decreasing. Drought has shown no clear increasing trend, nor has flooding. Hurricane intensity and number show no increasing trend. Globally, wildfires have shown no clear trend in increasing number or intensity, while in Canada, wildfires have actually been decreasing in number and areas consumed from the 1950s to the present.
  • While media and political activists assert that the evidence for increasing harms from increasing extreme weather is iron-clad, it is anything but. In fact, it is quite limited, and of low reliability. Claims about extreme weather should not be used as the basis for committing to long-term regulatory regimes that will hurt current Canadian standards of living, and leave future generations worse off.
