The Earth’s climate is changing in ways that affect our weather, oceans, ecosystems, and global temperatures. Human activities contribute to climate change, primarily through the release of billions of tons of carbon dioxide, methane, nitrous oxide, and other gases each year. These greenhouse gases, or GHGs, trap heat in the atmosphere and create changes in our climate, such as:

  • Changing weather and precipitation patterns
  • Increases in ocean temperatures, sea level, and acidity
  • Melting of glaciers and sea ice
  • Adverse impacts to water supply and water quality
  • Increased demand for electrical cooling
  • Increased smog and associated respiratory and heart-related illnesses
