"OTTAWA — The timing was coincidental, but the meeting had a new urgency.

One day after President Trump withdrew the United States from the Paris climate accord — saying he was elected to serve Pittsburgh, not Paris — the transport minister in Prime Minister Justin Trudeau’s cabinet visited with the mayor of Pittsburgh to discuss climate change.

The meeting was part of a broad strategy by the Canadian federal government to work directly with American states and cities on global warming, and to become a leader on the issue. Though the effort began several months ago, Mr. Trump’s rejection last week of the Paris agreement has energized it."
