Runoff and Flood Risk Increase
More intense rainfall events and regional increases in precipitation linked to climate change are increasing the risk of extreme runoff and flooding in some locations. Precipitation is a major driver for river discharge trends and for changes across annual and decadal time scales.
Streamflow levels are increasing alongside the increased frequency of heavy precipitation events across most of the US. In the largest rivers, including the Ohio, Missouri, and Mississippi, the number of days with high stream flow (the top 25 percent of readings) has risen over the past 30 years (1987-2016).[1]

Stream flow in Minnesota: Indicator of climate change
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.
