Snowpack Melting Earlier and/or Faster
Temperature directly influences mountain snowpack, which provides natural storage of precipitation during cold winter months until it melts and provides water in the form of runoff as temperatures warm. Over the past few decades, warming temperatures have been linked to changes in the percentage of precipitation falling as rain or snow, and snow melt anomalies showing a trend towards earlier and faster stream flow.

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.
