Greenhouse Gas Emissions
Human activities, primarily burning fossil fuels and deforestation, load the atmosphere with carbon dioxide (CO2) and other greenhouse gas pollution. The concentration of greenhouse gases in the atmosphere is now greater than at any other time in human history. Multiple lines of evidence show that CO2 levels are driving global warming.

Large influence of soil moisture on long-term terrestrial carbon uptake
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.
