• Explain greenhouse gases and the basics of climate change in a way that an elementary school child could understand. • Why do scientists and policymakers focus on carbon dioxide as a key driver of climate
Greenhouses gases are atmospheric gases such as carbon dioxide (CO 2), methane (CH 4), and water vapor (H 2 O) that absorb and re-radiate heat, which warms the lower atmosphere and Earth’s surface. This process of absorption and re-radiation of heat is called the greenhouse effect .
The greenhouse effect: some of the infrared radiation from the Sun passes through the atmosphere, but most is absorbed and re-emitted in all directions by greenhouse gas molecules and clouds. The effect of this is to warm the Earth’s surface and the lower atmosphere.
trace gases, such as carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2O) and ozone (O 3), which do absorb and emit infrared radiation. These so called greenhouse gases, with a total volume mixing ratio in dry air of less than 0.1% by volume, play an essential role in the Earth’s energy budget. Moreover the
Atmospheric Chemistry and Greenhouse Gases 241 Executive Summary Two important new findings since the IPCC WGI Second Assessment Report (IPCC, 1996) (hereafter SAR) demonstrate the importance of atmospheric chemistry in controlling greenhouse gases: Currently, tropospheric ozone (O 3) is the third most important greenhouse gas after carbon ...
21 sie 2024 · The greenhouse effect happens when certain gases, which are known as greenhouse gases, accumulate in Earth’s atmosphere. Greenhouse gases include carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2 O), ozone (O 3), and fluorinated gases.
10 wrz 2024 · The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat. This process makes Earth much warmer than it would be without an atmosphere. The greenhouse effect is one of the things that makes Earth a comfortable place to live.
