Global Warming Information Essay
What is Global Warming?
Global warming refers to an average increase in the Earth's temperature, which in turn causes changes in climate. A warmer Earth may lead to changes in rainfall patterns, a rise in sea level, and a wide range of impacts on plants, wildlife, and humans.
What is Global Warming caused by?
Global warming is caused by the "Greenhouse effect." Just like any other planet, the Earth absorbs the sun's heat and radiates it back towards space. But greenhouse gases trap heat and reflect it back towards the Earth. The more greenhouse gases in the atmosphere, the more heat that is trapped. The less the amount of greenhouse gases, the less heat that …show more content…
Where do greenhouse gases come from?
Almost all of the man-made carbon dioxide emissions come from the burning up of fossil fuels - coal, oil, and natural gas. Fossil fuels are created from plants and animals that died millions of years ago, and lie deep underground or under the ocean floor. When we burn these fuels, we release not only energy, but also CO2.
Of all the greenhouse gases we release by burning things, CO2is the greatest contributor to the man-made increase in the greenhouse effect. Not only do we emit huge amounts of CO2, but it also takes a very long time to disappear from the atmosphere after it has been emitted. Since the Industrial Revolution, people have emitted large amounts of CO2through the consumption of fossil fuels such as coal, oil, and natural gasses. Although it is not all man made pollution that is causing Global warming. The worst offenders are volcanoes, which erupt huge amounts of greenhouse gases.
Although most emissions of CO2come from natural sources, such as rotting vegetation, it is the emissions from human activity that tip the scales and create the imbalance that leads to global
