Global Warming Truth Or Scare
...scientist in the world believes it is. Left unchecked, global warming's negative effects on our natural environment could have catastrophic consequences not only for our planet and wildlife but for mankind as well.
What is global warming you might ask? Global warming is a phenomenon where Carbon Dioxide (Co2) gas commonly called green house gas, gets trapped in the Earth's atmosphere. The trapped Co2 blocks excess heat from passing back through the Earth's atmosphere and into space, this causes our planet to get hotter and stay hotter than it normally would. Now, you may be thinking great longer summers! It's not great, in fact it's frightening.
Co2 is distributed into our atmosphere mainly by humans burning fossil fuels like coal, oil, and gas (Flannery, T, 2005). We burn these substances to generate electricity to power our factories, gas to power our cars, and oil to heat our homes.
Now, there are natural causes of Co2 emission into our atmosphere, for example dead decaying trees, plants, animal carcasses and waste. However, the natural levels of Co2 in our atmosphere in the past 600,000 years have been at un-harmful levels. This is an undisputed scientific fact, proven by the testing of ice cores collected from the world's great ice sheets, which exist on land as ice pack and in the oceans as glaciers. (Al Gore, Inconvenient truth).
Scientists examine these ice cores in laboratories and can determine precisely what elements and the quantity of those elements that existed in Earth's atmosphere when that water froze.
600,000 years of data is a very solid base of information from which to construct CO2 emission models from. Armed with this data, scientists constructed a model of the Earth's natural CO2 levels over that 600,000 period. Based on these models, it has been determined with scientific accuracy, that...
