From 50 years back, the subject of climate change and global warming started to become an issue of discussion. After the industrial revolution in Europe, WWI, and WWII increased amounts of gasses were released to the atmosphere. The result of such emissions started to be in effect in the 70s of the last century. Melting Polar ice, climate changes, Ozone layer degeneration and many other occurrences signaled that a change is on the way. What we call today Global Warming summarizes all that.Maybe the effects of the deteriorating global equilibrium started to take minor shapes in the decades ago. Some weather systems that were seen abnormal were related to an occurrence that may happen once in every several hundred years. But the repetition pattern of such systems and the increased severity of them rang the bell;" where are we still going?" Our earth is retaliating.
Such factors are gaseous emissions and chemicals releases where not the mere reason for the problem. An important factor added and fastened the process. De-forestaion. Huge areas of green forests were eradicated from the Amazon basin, south-east Asia, Central Africa, and the Russian Tundra. The mass de-forestation resulted in three devastating outcomes:
1- the deprivation of several billion tons of released oxygen, vital for all organisms.
2- the unveilance of huge areas of the earth's crust from green coverage, thus eliminating a heat filter that decomposed the sun's heat into the photosynthesis process and thus increasing the heat radiation into the atmosphere, resulting in an overall atmospheric temperature increase.
3- mud slides and erosion became an easier phenomena especially that the lands were the forests have been pulled out are subjected to heavy rain fall and huge rivers' passage, thus additional billion of tons of land soil have been transported towards the sea.
The combination of the whole up-mentioned factors created the Global Warming Problem, which we are facing its severity nowadays and still in the days to come.
As Global temperature continues to rise, even if the scale appeared minimal to us (0.5 degree per several years) but that will bring tremendous changes to the weather system as a whole. As known, most of the weather systems are formed over the oceans. Rising humid warm air from the equatorial plate finds its way towards the northern and southern poles respectively. This created a low pressure area over the Equator. Cold air from the poles moves towards the equator to fill the gap in pressure change. This process summarizes the meteorological process all over the globe.
With an increase in the earth surface temperature, warmer air fronts will form and will rise up into the atmosphere in a faster movement. Thus a deeper low pressure system will be formed bringing heavier rains and winds. And if the 0.5 degree figure appears minimal to you, you should know that a 0.25 degree change in the air temperature feeding Hurricane Katrina would have changed its course of movement towards the ocean and calmed down its winds gusts with a great difference. Thus, continuing ocean-surface temperature increase will be a fertile place for the birth of Katrina-like weather systems, the latest witnessed is Hurricane Gono.
What was abnormal with GONO wasn't its severity and heavy rain accompanied. On the contrary that’s a normal outcome. But what really raised the interest in it was its extensive approach towards the Northern Latitudes. It didn’t stop in Oman at all, it continued its way towards eastern UAE and Iran releasing the tremendous amounts of energy it gained from the warm Indian Ocean waters. Thus in the future, with a continuous increase in oceanic temperatures, it will not be strange to see hurricanes striking KSA, Kuwait and Northern Iran.
Solutions to the Global warming process were debated by a jury of international scientists. They kept the condition of gaseous emissions fixed and worked on changing the other variable, the sun heat.
One proposed that sprinkling several tons of tiny mirrors in the outer stratosphere will reflect a huge amount of the suns heat and thus decrease the Earth's temperature. Another proposed to inject the ozone layer with Ozone molecules. These molecules are known for their ability to absorb UV rays and thus protecting the earth from harmful radiation and sun's heat.
A third scientist went further in the mirror strategy. He said that it is possible to create a belt of reflecting mirrors around the earth in a distance that exceeds the moon. This will relief the Earth from increased heat.
The main withdraws of such techniques was their expensive implementation. Not only that, but they need to be maintained all over the years, that’s why they are still under negotiation.
Till then, we will stay to witness natural severity and it may bypass the pattern of hurricanes and storms. It may take the shape of drought and rain embolism.
Every one is responsible in reducing gaseous emissions even though he/she think that his contribution has no effect. We all know that if everybody does his homework, we can create change or merely minimize the devastating outcomes.
