Land Ice and Snow Cover Decline
Snow and ice cover have decreased in most areas across the globe. This trend is especially stark in the Northern Hemisphere where spring snow cover has declined rapidly. Scientists agree, human-caused global warming is the dominant cause.

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.
