Surface Ozone Change
Surface-level ozone (also referred to as ground-level or tropospheric ozone) poses a serious risk to human health. Climate change influences surface ozone and its precursors through multiple processes: changes in air temperature and water content affect the air's chemistry and the rates of chemical reactions that create and remove ozone.

Earth Systems Signals
Global warming is causing widespread and rapid changes in the atmosphere, ocean, cryosphere and biosphere.
Heat Signals
The Earth is getting hotter due to human activities that release heat-trapping gases into the atmosphere.
Drought Signals
Climate change is making droughts more likely to occur, and more severe when they do.
Wildfires Signals
Climate change is increasing the size, frequency, intensity and seasonality of wildfires.
Hurricanes Signals
Warmer temperatures increase the rate of water evaporation, which feeds moisture and energy into storms.
Floods Signals
Worsening floods due to climate change are putting a growing number of communities at risk.
