=  = = = =THE GREENHOUSE EFFECT= = Gasses that trap heat in the atmosphere are greenhouse gasses. It is a natural occurring process in where the earth’s atmosphere keeps the earths warm temperatures. The changes in the atmosphere have affected temperature, weather, and sea level. Carbon Dioxide, Methane and Nitrous have all increased since the Greenhouse Affect has begun. Ever since the mid 1970s, the regular exterior temperature raised around 1 degree. The surface of the earth is now warming at a rate of 0.32 degrees a decade or 3.2 a century. Many other countries have also developed national greenhouse inventories. The greenhouse affect is necessary for our survival because it is what maintains the earths warm temperatures. = = =



GLOBAL WARMING: THE BIG PICTURE
== Global warming in effecting are planet and everyone on it. The earth is heating up at alarming rates and its not slowing down. We need to start to stop these factors or at lest slow them down. The greenhouse gas emissions will increase in the next century unless greenhouse gas concentrations decrease substantially in the years to come. A long time ago we used to have ice ages and now we have heat waves every Summer and now even sometimes in the Spring. ** GLOBAL WARMING: CONTRIBUTING FACTORS ** There are many contributing factors to global warming. One contributing factor to global warming is overpopulation. As more people come onto are planet the earths temperature increase‘s. We drive cars, produce waste, produce gas emissions, and use up gases that are unproduceable. Cars burn fuel and make carbon dioxide. Cows produce Methane by. Methane, Carbon Dioxide and Nitrous are all also major contributors to the rise in temperatures. They are all increasing because of the greenhouse affect. ==

==GLOBAL WARMING: LOCAL EFFECTS Global warming is affecting everyone and everything. It is melting the glaciers which provide a crucial habitat for species that will now go extinct because of Global Warming. The air we breathe is becoming dirty and less breathable because of all the toxic gas emissions. The temperatures have been rising significantly. Ever since the mid 1970s, the regular exterior temperature raised around 1 degree. The surface of the earth is now warming at a rate of 0.32 degrees a decade or 3.2 a century. The water level is rising because of global warming. The temperature rise causes the water to rise through thermal expansion in the water. Soon the places we live and care about will be emerged in water. The sea level is currently rising at a rate of 1.8 mm per year and lately rates at 2.8 mm to 3.1 mm a year. As you see the rate is increasing and the time is running away. This is extremely bad for the future of our environment.==
