Sea Level Rise
Global warming is behind the recent acceleration of sea level rise observed since record keeping began in 1880. The ocean, which has absorbed 93 percent of the heat that human activities have added to the climate system, expands as it warms, which pushes up sea levels. Warming also melts glaciers and ice sheets on land, with the run-off adding to sea levels.

Temperature-driven global sea-level variability in the Common Era
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.
