  • It is largely absorbed in the atmosphere and only a modest amount of this light arrives at the surface of Earth. (ucsd.edu)
  • For most of human existence, the amount of CO2 in the atmosphere has been stable at about 280 parts per million (ppm), meaning that out of every million molecules in the air, 280 of them are carbon dioxide. (skepticalscience.com)
Coal2
  • Fossil fuels include coal, petroleum, and natural gas . (encyclopedia.com)

  • These substances include various gases and and liquid droplets found in the air. (cdc.gov)
Sun's1
  • Climate has changed throughout geological history, for many natural reasons such as changes in the sun's energy received by Earth arising from slow orbital changes, or changes in the sun's energy reaching Earth's surface due to volcanic eruptions. (ametsoc.org)
Increase6
  • It is the increase in carbon dioxide and trace gases that has altered atmospheric chemistry. (encyclopedia.com)
  • This increase in greenhouse gasses has had some startling effects on the natural communities on Earth. (exploringnature.org)
