chlorofluorocarbons Show The U.S. government banned the use of CFCs, and today, more than 197 United Nations countries have agreed to basic protocols designed to preserve and protect the ozone layer. However, some CFC replacements may also cause ozone-layer damage. Greenhouse gases are gases that accumulate in the atmosphere, where they contribute to global warming by trapping heat near the earth's surface. Particulate matter, such as soil, dust, and volcanic ash, is a naturally occurring air pollutant. Exposure to polychlorinated biphenyls (PCBs), which were used for many years as insulating materials in high-voltage electrical equipment, is associated with birth defects, cancer, and skin problems. 1) Over the last 200 years, the amount of carbon dioxide (CO₂) in the atmosphere has been rising 2) The global temperature has also risen during this time - this global warming 3) There's lots of evidence that the rise in carbon dioxide has increased the greenhouse effect, causing global warming 4) More carbon dioxide means less heat escapes the atmosphere, so the temperature of the Earth increases 5) Global warming there's a scientific agreement that humans are causing global warming 6) Global warming is a type of climate change and it also causes other types. For example, changes in the weather 7) Carbon dioxide levels are rising for three reasons: • Increased carbon dioxide emissions - burning fossil fuels releases carbon dioxide • Increased energy usage - we use more electrical gadgets, and travel more in cars and planes. To produce the extra energy we burn fossil fuels, which releases carbon dioxide. • Deforestation - carbon dioxide is released when trees are chopped down and burnt to clear land Recommended textbook solutions Environmental Science for AP3rd EditionAndrew Friedland, Rick Relyea 957 solutions Applications and Investigations In Earth Science9th EditionDennis G.

Wright 569 solutions How does excess CO2 in the atmosphere contribute to global warming quizlet?C02 is one of several atmospheric greenhouse gases. Greenhouse gases trap infrared rays and promote the warming of the atmosphere. How do greenhouse gases contribute to global warming? These gases trap heat and warm the lower atmosphere, similar to the effect of the trapping of solar heat by a greenhouse.
What contributes to carbon dioxide in the atmosphere?Natural sources of carbon dioxide include most animals, which exhale carbon dioxide as a waste product. Human activities that lead to carbon dioxide emissions come primarily from energy production, including burning coal, oil, or natural gas.
How do carbon emissions lead to global warming quizlet?Increased greenhouse gas emissions have an effect on global temperatures. The combustion of fossil fuels produces carbon dioxide gas. Scientists believe that the release of large amounts of carbon dioxide into the atmosphere will cause the Earth's surface temperature to increase and the pH of the oceans to decrease.
Which of the following is the main cause of global warming carbon dioxide?Greenhouse gases
The main driver of climate change is the greenhouse effect. Some gases in the Earth's atmosphere act a bit like the glass in a greenhouse, trapping the sun's heat and stopping it from leaking back into space and causing global warming.
