Opinion: The Parliamentary Budget Officer just debunked climate alarmism – by Ross McKitrick (Yahoo Finance/Financial Post – December 7, 2022)

Ross McKitrick is a professor of economics at the University of Guelph and senior fellow of the Fraser Institute.

The Parliamentary Budget Officer (PBO) recently released a report on the effects of greenhouse gas emissions on Canadian GDP growth over the next 80 years. I’ve written previously about the recent economics literature investigating the link (or lack thereof) between global warming and economic growth.

It’s a fascinating topic and I’ve been actively working with on it one of our PhD students for several years. While I would quibble with some aspects of the PBO report, the overall conclusions are not out of line with mainstream thinking on the topic. Which is why the findings are so astonishing and radical compared to what the government has been saying.

The PBO estimated what would happen to the Canadian economy between now and 2100 if temperatures and precipitation change as expected due to greenhouse gases.

The report’s authors consider two scenarios — first, if emission-reduction policies stall at today’s levels and nobody complies with their Paris commitments and, second, if countries comply with all their Paris commitments in full and on time. Under the first scenario Canada’s GDP in 2100 will be 6.6 per cent smaller than it otherwise would be.
