We all have heard the term Global Warming and the effects it will have on the planet, we have also heard of the collective efforts of the worlds economies to reduce it, if not eradicate this problem.
Heres the definition of global warming according to
wikipedia :
"Global warming is the increase in the average measured temperature of the Earth's near-surface air and oceans since the mid-twentieth century, and its projected continuation."What this means is that the temperature of the atmosphere around us is steadily increasing and causing the earth to become warmer..
But heres the problem, according to recent studies conducted on "pan evaporation" in Australia, Russia, Germany, Israel and the Maldives, the amount of sun's rays reaching the earth as decreased by a drastic level i.e that there's a 22% reduction of the sun's rays reaching earth....
How this "pan evaporation" test works is simple, we fill a big pan with water and document the amount of water that has evaporated and how much temperature is needed to evaporate that amount of water....
What the scientists concluded was astounding, there was actually a "decrease" in the amount of evaporation taking place, now some you might think that thats just crazy, due to global warming there should be an "increase" in the amount of evaporation....
But thats not the case, the process of evaporation doesn't actually depend on the temperature, rather it depends on the sun, the humidity and the air ,so if the amount of evaporation has reduced then it is logical to believe that the amount of sun-rays reaching us has reduced too!
But this causes a paradox with the global warming phenomenon, heres what the scientists have found out......
Global warming is caused by the green-house gases that we release into the air when we drive a car, or because of a forest-fire. These green-house gases which include soot, ash and other particles is blocking the amount of heat that was supposed to escape the earth's atmosphere, in turn making the earth hotter, now these same particles are also affecting the clouds. Now clouds are formed when water-vapour condenses and sticks to naturally forming particles, but with the amount of artificial man-made particles increasing, the amount of clouds formed is more and they are denser, these man-made particles are smaller compared to the natural particles but they are huge in number, so in essence many smaller particles reflect more sunlight than few large particles, effectively making the clouds as huge mirrors in the sky......this effect is reducing the earth temperature significantly.....
So theres a kind of tug-of-war between global warming and global dimming.....
One pulling earth towards a hotter climate and the other pulling it to a cooler climate.....
So what this means is that the green-houses gases that we let out are giving a double-whammy..
The effects of global dimming are already felt, in the 1980's, Ethiopia was hit by one of the worst documented famine that affected more than 50 milllion people and stunned the world, now scientists are lead to believe that this was a direct effect of global dimming, due to pollution caused by the American and European countries the amount of particles in the air increased, in effect making the earth cooler and less water was evaporated, leading to less rain clouds, which drifted towards the south, and the life-giving rains of Ethiopia failed...
And scientists believe that this was just a preview of what could happen........
Imagine a similar situation here in Asia, with more than half the earth's population living here, the effects could be disastrous!!
Now scientists are believing, if such a phenomenon existed and was overlooked for so many years than most of today's global warming models are incorrect....
Now, global dimming is cooling the effect of global warming nearly by 50% percent, imagine what would happen if global warming won the tug-of-war, there could be a drastic temperature increase of nearly 10 degrees!! A similar kind of event took place under natural occurrences albeit about 50 million years ago!! So this was an extreme global warming, the big daddy of global warming!!!
So ironically, the pollutants that we emitted actually cooled the earth down enough to blind us from, what could be so deadly a global warming phenomenon, our children could be living in a world where the temperature could sour unto 10 degrees!!!
Scientist believe that after this decade if the global warming was not controlled and kept within 1 degree then we would be at a point-of-no-return, and the earth which was so hospitable would not so hospitable....
Further, with a stark rise in temperature, all the natural green-house gases that are stabilized deep within the oceanic floor would be destabilized and start bubbling out... there's more the 10 billion cubic tonnes of methane gases within the ocean, methane is 3 times more dangerous than carbon monoxide, leading to a further increase in the temperature, upto even 25 degrees. The diminished water vapor in the air could lead to entire rain-forests getting burned out,large scale soil erosion. With a steep temperature rise as this, most of the plant life would not able to withstand it, eventually dieing out.....
So it is upto us, to save out planet, it is upto us to present a better, greener world to our children, it is upto us, to decide the fate of our home......our earth
One Home.One Earth.
This is nuspeed cycling out......
adios and take good care of yourself our your environment....
Go green...
