As of 2016, the warming effect of long-lived greenhouse gases in Earth's atmosphere had increased by approximately 40% compared to 1990.

Carbon dioxide is everywhere: in the air, rising from cracks in the ocean floor, and in your soda can. Now it's showing up in the news! Find out why carbon dioxide is such a hot topic, and why it's going to be around for a long, long time.

Human activities, mainly burning fossil fuels, are increasing the concentration of carbon dioxide in our atmosphere, amplifying the natural greenhouse effect.

NOAA's Susan Solomon was awarded the 2009 Volvo Environment Prize for her pioneering contributions in atmospheric chemistry and physics.

This activity involves plotting and comparing monthly data on atmospheric C02 concentrations over two years, as recorded in Mauna Loa and the South Pole, and postulating reasons for differences in their seasonal patterns. Longer-term data is then examined for both sites to see if seasonal variations from one site to the other carry over into longer term trends.

Students explore the carbon cycle and the relationship between atmospheric carbon dioxide concentrations and temperature. Students create and compare graphs of carbon dioxide and temperature data from one local (Mauna Loa, Hawaii) meteorological station and one NASA global data set. These graphs, as well as a global vegetation map and an atmospheric wind circulation patterns diagram, are used as evidence to support the scientific claims they develop through their analysis and interpretation.
