The heat of carbon dioxide can be 11,000 times greater than the heat of a single molecule of cfc-12. “This is the largest cache ever found in the U.S., and it’s just the beginning of what we’re going to find,” EPA Administrator Gina McCarthy said at a news conference in Washington, D.C., on Tuesday.

What type of gas are CFCs?
(CFCs) are nontoxic, nonflammable chemicals containing atoms of carbon, chlorine, and fluorine. They are used in the manufacture of aerosol sprays, blowing agents for foams and packing materials, as well as in refrigerators and air conditioners.
(EPA) and the European Union (EU) have banned the use of CFC-11 and -12 in air-conditioning and refrigeration systems. Commission has also banned their use in aerosols. States, however, the EPA has not yet issued a ban on the chemicals.
Are CFCs the worst greenhouse gas?
The most important factor is carbon dioxide. The second bar contains halocarbons, such as chlorofluorocarbons. Carbon dioxide has stronger effects on global warming than other factors. The third bar shows how much of the world’s greenhouse gas emissions come from the United States, China, the European Union, Japan, India, Brazil, Russia, and South Africa. These countries account for more than 80 percent of global emissions, according to the Intergovernmental Panel on Climate Change.
What are the four main greenhouse gases?
It is produced by all living things, including plants and animals, as well as by human activity. For more information, see Carbon Dioxide and Global Warming. (N2O) are two other greenhouse gases that are produced when fossil fuel combustion is combined with water.
Which is not a greenhouse gas?
Carbon dioxide, methane, chlorofluorocarbon, ozone, nitrous oxide, and water vapor are greenhouse gases. The gas which is not a greenhouse gas is called a non-greenhouse gas. This imbalance is caused by the fact that the Sun’s energy is reflected back into space, while the heat that is absorbed by plants and other living things is radiated back to space.
The result of this is that more heat is being absorbed than is leaving the planet. As a result, Earth is getting hotter and hotter, with the average temperature increasing by about 1.5 degrees Fahrenheit (0.8 degrees Celsius) per decade since the beginning of the Industrial Revolution in 1750, according to the U.S. National Oceanic and Atmospheric Administration.
Why are CFCs worse than CO2?
They’re being phased out with good reason: On a molecule-by-molecule basis, CFCs have a much higher global warming potential than carbon dioxide. According to a study published last year in the Proceedings of the National Academy of Sciences, CFC-13, which cools some industrial freezers, is 16,400 times warmer than carbon dioxide over the course of a century.
“It’s not a question of if it’s going to be a problem, but when,” said Michael Halpern, a climate scientist at Columbia University’s Lamont-Doherty Earth Observatory in Palisades, N.Y., who was not involved with the new study.
