Drought Risk Increase
Global warming drives drought through changes in both precipitation and temperatures that vary by region. Depending on a region’s latitude, climate change can reduce or increase the total annual precipitation. It can also concentrate the year’s precipitation into fewer but heavier downpours. This can lead to more runoff, which contributes to drought. Global warming can also raise local temperatures and drive more frequent and intense heat waves, all of which can dry out land and prompt the early melt of snowpack, another contributor to drought.

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.
