Climate change and health in California

Climate change is altering seasonal patterns in California, USA, making hot days hotter, and increasing the severity of extreme events. As a result, Californians face a variety of increasing health problems such as more heat-related illnesses, breathing and heart troubles, food and water contamination, traumatic injuries, mental health challenges, and exposure to infectious diseases. These threats will only worsen without action to limit carbon pollution and build resilience to the present-day threats of climate change.
