HOW TO REDUCE GLOBAL WARMING GLOBAL WARMING Definition of global Global warming is an average increase in the temperature of the atmosphere near the Earth’s surface and in the troposphere, which can contribute to changes in global climate patterns. warming melting of ice caps DROUGHT polar bear EXTINCTION Effects of global warming HOLE in the O-zone layer REDUCE THE CUTTING OF TREES REDUCE THE USAGE OF CARS AND OTHER TRANSPORT Use a more energy efficient vehicle recycled plastic toys. save energy by unplugging Use energy efficient washers and dryers. A VIDEO ON GLOBAL WARMING what you do counts! What causes global warming? Global Warming is caused by many things. The causes are split up into two groups, man-made and natural causes. Natural causes Natural causes are causes created by nature. One natural cause is a release of methane gas from arctic tundra and wetlands. Methane is a greenhouse gas. A greenhouse gas is a gas that traps heat in the earth's atmosphere Man-made causes probably do the most damage. There are many man-made causes. Pollution is one of the biggest man-made problems. Pollution comes in many shapes and sizes. Burning fossil fuels is one thing that causes pollution. Fossil fuels are fuels made of organic matter such as coal, or oil. When fossil fuels are burned they give off a green house gas called CO2. Man- made causes What does this means? It means that the rate at which carbon dioxide is produce is faster then the rate at which oxygen is produce. Thus, we should all STOP the cutting down of trees, instead we should increase the number of trees in the world.

We should all STOP the burning of trees!

We should all help to save the earth from global warming, we should save energy, conserve energy, etc...... Global Warming
The world's energy is principally carbon-based
Over 85% of the world energy supply is carbon-based
Complex molecules are made up of carbon bonded with other elements, especially oxygen, hydrogen and nitrogen, and carbon is able to bond with all of these. IT CONTRIBUTE TO THE DISTRACTION
OF OUR PLANET! HOW DO WE KNOW THAT WE ARE CAUSING GLOBAL WARMING? NIGHT WARMING FASTER THAN DAYS! WINTER WARMING FASTER THAN SUMMER LESS OXYGEN IN THE AIR LESS HEAT ESCAPING TO SPACE MORE FOSSIL FUEL CARBON IN TREES MORE FOSSIL FUEL CARBON IN CORALS Do what's right! THANK YOU FOR YOU ATTENTION!

THE END! DONE BY: KRYSTAL(07) & KAI TING(09) CLASS 2E3 NO! NO! NO! NO! IT'S MELTING!!!
