Precipitation Falls as Rain Instead of Snow
With incremental warming, significant fractions of snowfall events shift to rainfall events.[1] Rising temperatures have a larger effect at locations and elevations near the freezing level where small changes in temperature can determine whether snowpack melts and whether precipitation falls as rain or snow.[2]

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.
