Global warming is the increase in the average temperature of Earth's air and oceans and also the projected continuation of this rise. Its main causes are increasing concentrations of greenhouse gases from activities like fossil fuel burning, deforestation, and the population's excess use of electricity and technology.

The greenhouse effect is the cycle of Earth's absorption and emission of infrared radiation by gases in the atmosphere. The normal atmosphere traps some heat in our atmosphere and is in our benefit as it maintains the global climate at a level suitable for survival. However, due to the increase in carbon dioxide levels and ozone layers, excess heat has been trapped leading to the exponential increase of the Earth's water and air temperatures.

Not only are there statistical evidence of the dramatic increase in Earth's temperature by scientific research, global catastrophes and record highs are just foreshadowing events to a potentially disastrous period of time. Scientists have measured and analyzed the trapped bubbles of carbon dioxide in Antarctica ice shelves to discover a shocking trend. In the last 650,000 years, carbon dioxide levels have never passed 300 parts per million; however, in just the last few decades, it has passed well over 600 parts per million and expected to only shoot up more in the next 50-70 years. Additionally, carbon dioxide levels are correlated with the Earth's temperature; an influx in carbon dioxide level will only mean a dramatic and potentially dangerous and intolerable increase in heat. Physical traces of global warming- springs in the Himalayas drying up and leading to a forty percent decrease in water supply, flooding of up to 35 inches in Mumbai, India and China- have been ignored and left out of news reports. On the other hand, Hurricane Katrina, a terrible tragedy resulting from the brewing temperatures of the sea floor, has not been unnoticed. It is, undoubtedly though, not the only global tragedy.
