Droughts and Heatwaves


Climate change will increase the intensity and frequency of droughts and heatwaves. Heatwaves are short (usually week-long) periods of intensely hot weather, while droughts are long-term periods. Both droughts and heatwaves will increase since there is simply more hot weather, which allows for more of them. They both affect human health, water supply, and agriculture by causing heat-related disease and drying out water resources and soil. We're already seeing this, with 120+ºF measures multiple times in the past decade.
