London continues to feel the heat as climate change continues to push summer temperatures higher and intensify extreme weather across the region.
“London and much of Canada are experiencing more intense and frequent heat waves, a phenomenon directly linked to climate change,” says Gordon McBean, professor at Western University.
“We are certainly in a warming climate regime, worldwide and in Canada,” McBean. “This is resulting in, and will continue to result in, rising heat domes with greater severity and likely more frequency than ever before.”

“Unfortunately, heat waves hit most often the elderly and those in economic situations where cooling is not possible,” he added. “We have to recognize the human cost of these events.”
London has traditionally experienced about 10 days of 30°C-or-higher heat through the summer. But with ongoing climate warming, McBean expects the number of days will increase to anywhere from 40 to 70 per summer by 2100, depending on greenhouse gas emissions.
“That’s a gigantic increase, with big impacts not only for people’s health but also for ecosystems, trees, plants and wildlife,” he said.
“Heat already is the leading weather-related killer in America, ahead of floods and tornadoes,” McBean said. Underscoring the need for preparedness and resilience on the community’s part.

Local adaptation efforts, such as public education campaigns and cooling centres, will be essential, but McBean stresses that there is also an overall need to reduce the emission of greenhouse gases everywhere. The World Economic Forum’s 2025 global risk report highlights extreme weather conditions as the biggest threat to the next decade.
“Canada is warming at about twice the global rate,” McBean said, and some regions are seeing increases three or four times larger.
With London and other societies experiencing hotter summers and more intense weather, McBean’s message is unambiguous: climate change is not some future menace but a current reality that must be addressed now.
