Global warming means the increase in the earth’s atmospheric temperatures. The gradual increase and decrease in the earth’s atmospheric temperatures over time is a natural process, but the majority of scientists agree that this process has been artificially and exponentially sped up by man-made greenhouse gas emissions. The global warming problem has now become widespread knowledge and the time has come to act.
Here are 7 of some of the most interesting and astonishing global warming facts:
*Even though greenhouse gas emissions are considered to be responsible for global warming, the truth is that the foremost cause of global warming is due to the excess of water vapor present in the atmosphere. Then comes the carbon dioxide, chlorofluorocarbons and nitrous emissions. Keep in mind though that global warming facts such as this one regarding water vapour do not mean that we should stop focusing on reducing CO2 levels, as they still have a big impact on the earth's climate.
*Without the water vapor that is present in the atmosphere which helps to warm the earth; the earth’s temperatures would be consistently below freezing.
* Cows contribute to global warming. When cows poop, they release methane gas (this is why cow dung smells worse than any other animal dung) and methane gas is lethal to our atmosphere.
*For the earth’s atmospheric temperatures to cool down, a few major volcanic eruptions would do this. A volcanic eruption releases great amounts of sulfuric acids into the atmosphere which combine with the water vapor and form a shield which then reflects some of the sunlight away thus, helping to cool down the temperatures across the globe for a couple of years or more (depending on the amount of gases released by the volcano).
*Everyone knows that aerosol is harmful not only to humans, but also to the atmosphere. However, not all aerosol particles cause harm to the earth’s atmosphere, and some do exactly the opposite, and they help protect it. The process of coloration of aerosol particles alters their relationship with the sun. Lightly colored particles reflect the sunlight away from the earth while darkened particles absorb sunlight.
*Clouds also play their role in warming or cooling the earth’s atmospheric temperatures. Wispy or cirrus clouds follow the same rule as cotton candy. Just like cotton candy absorbs the mouth’s moisture (and heat) and dissolves quickly, cirrus clouds also trap sunlight and thus play their role in warming the atmosphere. On the other hand, thicker clouds play their role in cooling the atmosphere by reflecting the sunlight.
*Ever wonder why scientists are so concerned about the melting ice caps, glaciers and the melting of the poles? Well, this is not just because of the rising sea levels that this causes. Humans are essentially destroying their greatest ally against global warming as ice caps and snow reflects a great deal of sunlight, and help keep the earth cool. With the ice caps melting, run-away warming could ensue at a rate which would be disastrous for humankind.
Global warming is a global disaster in the making. However, the most unfortunate thing is that, with the world economy based on fossil fuels, few nations are taking substantial corrective measures; maybe the world needs a “the-day-the-earth-stood-still” event to wake up from its slumber.
