A dangerous false choice: how we talk about extreme heat

The author contends that treating the need for immediate heat adaptation and the long-term goal of reducing emissions as a trade-off is a 'dangerous false choice.' While some argue that focusing on emissions neglects immediate safety, and others suggest air conditioning worsens heatwaves, the document asserts that both are necessary. It argues that the solution lies in decarbonizing the electricity grid to provide clean, affordable power for cooling, while simultaneously improving home insulation and urban shading to reduce energy demand.

• The argument that air conditioning significantly worsens heatwaves is not supported by science; while waste heat can increase street-level temperatures in dense urban cores, the effect is localized and small, typically peaking around one degree at night.
• Climate adaptation without emissions reduction is unsustainable because every increase in global warming intensifies heat to a point that may eventually exceed the capacity of governments, communities, and the human body to adapt.
• The conflict between cooling needs and emissions targets can be resolved by building faster and more flexible electricity systems to provide clean, affordable, and abundant power for home cooling.
• Failure to prioritize both adaptation and mitigation has lethal consequences in Canada, as evidenced by the 2021 heat dome which caused over 600 deaths in British Columbia, primarily among people indoors without cooling.
