Understanding Heat Waves and Climate Change
The increasing frequency and intensity of heat waves are linked to climate change. Rising global temperatures are creating conditions that make extreme heat events more likely. The Environmental Protection Agency (EPA) provides extensive resources on the impacts of climate change and strategies for adaptation [2]. Preparing for and mitigating the effects of heat waves is becoming increasingly crucial for public health and safety.
