The “heat dome” settles in western Canada, bringing sweltering temperatures

Last week, CBC meteorologist Johanna Wagstaffe said the thermal dome is set to break records.

“The falling air will push the air close to the ground, essentially like a pressure cooker,” Wagstaffe said.

“This summit is not going anywhere anytime soon.”

And climate change means these trends aren’t going away anytime soon, Wagstaffe said.

“We are breaking very old records, and that is still an indication of climate change,” she said. “But we are also breaking records from just a few years ago.

“And every time we see some pretty new records, it means our baseline changes.”
