A similar temperature swing on Earth would have produced an environment hostile to most living things. All gases whose molecules have three or more atoms are greenhouse gases—carbon dioxide (CO 2), water vapor (H 2 O), and methane (CH 4) are important greenhouse gases that have maintained Earth’s warm temperature for billions of years. Greenhouse gases include water vapour, carbon dioxide, methane, nitrous oxide, ozone and some artificial chemicals such as chlorofluorocarbons (CFCs). The greenhouse effect is important, because it contributes to the survival of life on Earth. According to the IPCC via the EPA, in 2014, the global breakdown of greenhouse gas emissions was as follows: carbon dioxide from fossil fuels, 65 percent; carbon dioxide from forestry and agriculture, 11 percent; methane, 16 percent; nitrous oxide, 6 percent; fluorinated gases, 2 percent. The greenhouse effect is the way in which heat is trapped close to the surface of the Earth by “greenhouse gases.” These heat-trapping gases can be thought of as a blanket wrapped around the Earth, which keeps it toastier than it would be without them. Human activities and the greenhouse effect. The greenhouse effect happens when certain gases—known as greenhouse gas es—collect in Earth’s atmosphere. By signing up, you'll get thousands of step-by-step solutions to your homework questions. As the warmth of the atmosphere increases, the amount of water vapor it can hold increases as well, further boosting the effect. (I mostly just remember making dioramas out of shoeboxes.).

According to a study by the Carbon Dioxide Information Analysis Center of the United States Department of Energy, carbon dioxide levels have increased 39.5 percent since 1750, while levels of methane in the atmosphere have jumped by 150 percent. Greenhouse gases include carbon dioxide, methane and nitrous oxides. Carbon Dioxide Information Analysis Center: Recent Greenhouse Gas Concentrations. The denser the atmosphere, and the higher the concentration of energy-holding molecules like water vapor and carbon dioxide, the more energy the atmosphere can trap. This ability to absorb and re-emit infrared radiation is the critical requirement for greenhouse gases. Because of the greenhouse effect, the Earth's actual average temperature is 14 degrees Celsius (57 degrees Fahrenheit). In the absence of this gas, plants will be unable to produce food. The most important naturally occurring greenhouse gas is water vapour and it is the largest contributor to the natural greenhouse effect. As humans continue doing activities that put greenhouse gases into the atmosphere — such as burning fossil fuels, producing trash, and raising livestock — the greenhouse effect continues to make our Earth a little less inhabitable for us. Read on for all the basics you need to know about the greenhouse effect, how it causes global warming, and what we can do to reduce our impact in terms of emitting greenhouse gases. The sun enters the greenhouse during the day, and the glass walls trap the sun’s heat, which warms up the air inside the greenhouse, even keeping the greenhouse warm overnight when the sun is down and outside temperatures are low. He began his writing career in 2007 and now works full-time as a writer and transcriptionist. This dramatic temperature change required NASA to develop specialized gear to protect astronauts from both extremes for the moon landings. As you can gather from the above information, the greenhouse effect is harmful to so many different ecosystems on our planet. As more greenhouse gases enter the atmosphere, its ability to trap heat increases. How to avoid generating greenhouse effect gases. It is important for life on Earth. The effect of mitigating factors, such as increased cloud cover reflecting sunlight back into space, is not well understood. On the lunar surface, with no atmosphere to mediate temperature swings, the surface can reach 134 degrees Celsius (273 degrees Fahrenheit) during the day and -153 degrees Celsius (-244 degrees Fahrenheit) at night.
