Climate change and associated extreme weather pose significant threats to human health.

The American Lung Association mentions these examples:

• Warmer temperatures and more droughts mean worsening air pollution from factors such as ozone, dust and wildfires.
• Since plants produce more pollen in warmer weather, climate change can mean worsening allergies.
• Wildfires, which are more common during drought conditions, can trigger serious problems for asthmatics, and people with heart or lung disease.
