Report on devastating Canadian climate change a far bigger issue than Jody Wilson-Raybould: Neil Macdonald

Government scientists have produced a new report on climate change in Canada, and it's beyond grim. The details trigger thoughts of hoarding and maybe selling the house and moving to higher ground. To a millennial, the findings should inspire naked fear.

Among other things, the report, which is scheduled to be released Tuesday, says:

Canada's climate has been warming at roughly twice the rate of the rest of the world. In Northern Canada, it's even higher.

And, says the report, there is simply no doubt about the cause. Climate change-skeptic conservatives will, of course, disagree, but here is what the scientists say:

"Canada's climate has warmed and will warm further in the future, driven by human influence. Both past and future warming in Canada is, on average, about double the magnitude of global warming."

Our climate is not warming consistently. It is most pronounced in the Prairies and British Columbia, and especially severe in northern B.C. The effects are strongest in winter.

It is effectively irreversible. The antidote prescribed in the report is politically impossible, at least right now: "Scenarios with limited warming will only occur if Canada and the rest of the world reduce carbon emissions to near zero early in the second half of the century."

The scientists predict an eventual increase in "annual average country-wide temperature" of about two degrees Celsius, a rate that will remain steady after mid-century. They say the increase could be as severe as six degrees.

The oceans around Canada have become more acidic and less oxygenated. Future warming will be heaviest in ice-free waters of the Canadian arctic. Most Canadians can expect coastal flooding to increase during their lifetimes.

Warming of the oceans, in particular, is a truly vicious circle. According to the........
