Trump’s worst move

In the long catalogue of destructive things that U.S. President Donald Trump has inflicted on the United States and the world, pulling out of the most important global attempt to slow the impact of climate change must go down as the worst.

The torpedo that Trump has launched into the Paris climate accord is a reckless act of sabotage. It disrespects the rest of the world, the 194 other nations that signed on to the agreement. And it disrespects the planet itself, which by all scientific evidence is well on its way toward dangerous changes if we keep on our current course.

Trump’s decision means the U.S. will start the lengthy process of withdrawing from the Paris accord and stop paying into the fund set up to help poorer nations adjust.

His promise to negotiate a better deal if possible means little. Why on earth would the rest of the world rush to amend a painstakingly negotiated accord just to accommodate a bully who clearly cares little for anyone else?

And indeed, Trump’s announcement on Thursday was as remarkable for its tone as for its substance. He voiced the economic nationalism that was at the heart of his campaign for president, reminding the world that he was elected to represent “the citizens of Pittsburgh, not Paris.” It was “America First” — and damn the rest.

Following Trump on his misguided course would be wrong for Canada and wrong for the environment. Much better to continue with efforts to reduce emissions.

That will give Canada a much better chance to embrace the opportunities of the future. And, along with other governments, to lead on this crucial issue as Washington falls further behind.
