Natural gas is often held up as a solution to climate change, or at least a transition in the right direction, on the basis of producing less CO2 per unit of energy than oil or coal. Other factors are also relevant, however. Natural gas is mostly methane (CH4) which is a much more powerful greenhouse […]

The CBC is reporting on polling results pertinent to this fall’s federal election: CBC News poll takes snapshot of Canadians ahead of fall election. They say the cost of living was the top concern identified, followed by climate change.

This Montreal Gazette story opens with a line which I expect will become increasingly commonly heard as climate change impacts worsen: “Premier François Legault said Sunday it might be necessary to force people in flood zones to move away to avoid taxpayers having to constantly pay to repair their homes.” That seems sure to be […]
