Warm-up or Ice Age ?


" From time to time it is necessary that pestilence, famine, and war prune the luxurious growth of the human race " ( Aristotle ).
The above maxim is actually justify why, recently we, the people of the world, have a lot of natural disasters. The same thing happen to the climate of the world, where we have been talking a lot about global warming, on the other hand we forget that instead of that, we might have a reverse phenomenon like an Ice Age. Why ?
Some knowledgeable persons concerned with world climate hypothesized that man made pollution, like fossil fuel burning, forest fires, slash/burn in the tropical forest are believed to have a greenhouse effect on surface temperature which produce carbon dioxide, lead to global warming.
Reid Bryson ( University of Wiscounsin ) have different point to see that problem, he pointed out that the warming and cooling of the polar ice caps strongly influence the world climate.
The activities of of fuel burning, deforestation, industrial pollution and lot more man made pollutions are believed to have increased the amount of dust in the atmosphere beside dust originating from volcanic activities, could lower the earth temperature and most probably will initiating an ice age.
When polar ice caps have expanded, some carbon dioxide, which formerly dissolved in the oocean, will be released to the atmosphere, which eventually can be expected to warm up the surface temperature and then reverse the glaciation.
Whatever, the man made pollution is believed to disrupt the world weather patterns, so make the world clean and green is the main priority and of course control the world population and fight against critical world food production and resources are another emergency agenda.
