Atmospheric Moisture Increase
A warmer atmosphere holds more moisture—about 7 percent more per 1.8°F (1°C) of warming—and scientists have already observed a significant increase in atmospheric moisture due to the air’s ability to hold more moisture as it warms. Storms supplied by climate change with increasing moisture are widely observed to produce heavier rain and snow. Research indicates that the increase in atmospheric moisture is primarily due to human-caused increases in greenhouse gases.

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.
