Southwestern US Precipitation Decrease
There is considerable evidence that changing weather patterns linked to climate change are at least partly responsible for recent precipitation decrease in California and the southwestern US. There is also emerging evidence showing that climate change is shifting rainfall patterns, consistent with literature that projects climate change will lead to drying in the region by mid-century.

Effect of Reduced Summer Cloud Shading on Evaporative Demand and Wildfire in Coastal Southern California
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.
