The climate crisis is a health crisis fueled by an untenable status quo. It is threatening our food, water, and air, worsening disease and extreme weather, and putting our physical, mental, and social well-being at risk. While the threat of the climate crisis is universal, the speed and severity of the impacts are not. Those who did the least to cause this emergency suffer the most as climate shocks push inequitable and fragile health systems past the breaking point.
