The changes in the surface air temperature, referred to as the global temperature, brought about by the enhanced greenhouse effect, which is induced by emissions of greenhouse gases into the air.PowerPoint Presentation: How Global Warming Works Fossil fuels (coal, oil, natural gas) Carbon Dioxide (CO 2 )PowerPoint Presentation: What’s the proof that global warming is taking place?PowerPoint Presentation: Portage Glacier 1914 2004 AlaskaPowerPoint Presentation: Colorado River Arizona June 2002 Dec 2003We can stop global warming!: We can stop global warming!PowerPoint Presentation: What can you do to help solve the problem?Simple Things To Do: Simple Things To Do Turn off your computer or the TV when you’re not using it. Take shorter showers. Heating water uses energy. Keep rooms cool by closing the blinds, shades, or curtains. Turn off the lights when you leave a room. Use compact fluorescent bulbs.Simple Things To Do: Simple Things To Do Dress lightly when it’s hot instead of turning up the air conditioning. Or use a fan. Dress warmly when it’s cold instead of turning up the heat. Offer to help your parents keep the air filters on your AC and furnace clean. Walk short distances instead of asking for a ride in the car. Plant a tree. Recycle.PowerPoint Presentation: Please Stop Global Warming Because We Our EarthPowerPoint Presentation: Here We See Different Layers Of The EarthPowerPoint Presentation: What is Ozone? Ozone Layer? Ozone (O3) is a highly-reactive from of oxygen. Unlike oxygen (O2), ozone has a strong scent and is blue in color. Ozone exists within both the tropospheric and stratospheric zones of the Earth’s atmosphere In the troposphere , ground level ozone is a major air pollutant and primary constituent of photochemical smog In the stratosphere, the ozone layer is an essential protector of life on earth as it absorbs harmful UV radiation before it reaches the earth.What are CFCs? What can be done?: What are CFCs ? What can be done? Used as propellants in aerosol spray cans Used as refrigerants in fridges, freezers and air conditioning units Reduce the use of CFCs They are already banned in aerosols (1987) BUT they are still used as refrigerants Recycle fridges and air conditioning plantsPowerPoint Presentation: Ozone destruction by UV rays UV radiation from the sun releases the radicals Cl and ClO. Ozone is a highly unstable molecule so it readily donates its extra oxygen molecule to free radical species such as hydrogen, bromine, and chlorine. These compound species act as catalysts in the breakdown of ozone molecules.PowerPoint Presentation: Global CFC productionOzone hole measurements over the Antarctic region 1980-98: Ozone hole measurements over the Antarctic region 1980-98PowerPoint Presentation: Images of Antarctica Taken Indicate A Slow RecoveryPowerPoint Presentation: Questions What are the 2 mechanisms responsible for ozone depletion? Explain each mechanism. Explain 4 effects of ozone depletion. What efforts have been implemented to counter the effects of ozone depletion? Are there any signs that these efforts are working? What are some things scientist would like to see done in order to gain a better understanding on the effects of ozone depletion?PowerPoint Presentation: Thank You Presented And Made By Amar Ajay Abhishek.
