After a year plagued by extreme heat, deadly fires and smog, it will come as little surprise to many of us that 2023 is likely to be the warmest year on record globally. It is clear that we must address the issue of climate change. A growing body of evidence points to a link between our reliance on fossil fuels and their toll on public health. Take a recent study that warns of a double risk of fatal heart attacks due to a combination of extreme heat and fine particulate pollution. Epidemiological research also warns that children living near oil and gas wells are five to seven times more likely to develop lymphoma. Meanwhile, climate change threatens to widen existing disparities. Rising temperatures lead to higher cooling bills, and increased flooding leads to higher home insurance premiums. Resource-poor communities suffer increased exposure to heat, pollution, flooding, and the effects of extreme weather. Wildfires, poor air quality, evacuations, and power outages pose dangerous challenges for people with complex health conditions and their caregivers.
