Ocean Acidification Increase
Ocean acidification—driven directly by rising carbon dioxide levels in the atmosphere—is progressing steadily and measurably and is already taking a toll on sea life. Acidification is having a significant impact on the chemical composition of seawater, especially in colder basins like the Arctic where CO2 dissolves more readily. This change in ocean chemistry is threatening the healthy development of many marine species, and poses risks to humans who depend on oceans for their livelihoods.

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.
