Climate change is the single greatest challenge of the 21st century, according to the World Health Organization (WHO). It is not limited to impacts on the environment but has direct and indirect effects on our health and everyday lives. The direct effects are many. Across the globe, extreme heat, rising sea levels, floods, droughts, and storms have already led to tens of thousands of deaths every year. The roots of the climate crisis are also exacerbating another public health issue, air pollution. It accounts for approximately seven million premature deaths worldwide every year and is a major risk factor for diseases, including heart disease, lung disease, and stroke.
