Poles and Glacier Protection
Over the millennia, glaciers have experienced periods of growth and melting, their mass, as is the natural fluctuation dictated by climatic cycles. From 'the last decades, they have begun the decline that continues today.
As and when the ice melts, there is less and less solar energy being reflected from the ice and more and more absorbed by the ocean. A significant decrease in glaciers and ice covering the sea in 'polar regions has been registered. Thus, the thickness of the ice in the Arctic Ocean
increased from 4.88 m on average in 1980 to 2.75m in 2000, a decrease of 2.13 m in 20 years. Studies conducted during 2003 by the National Aeronautics and Space Administration (NASA) , the Arctic lost around 10% its permanent ice.
During the past century, temperatures in the northern regions has increased, average of 1.51 ° C, which produced the phenomenon of global 1'atmosphère, a phenomenon linked primarily to the concentration of greenhouse gases in the atmosphere. The largest projected temperature rise during this century, will vary between 2 ° C and 6 ° C and will affect primarily the northern regions of the 'planet. Also, methods of production of different energies have clearly demonstrated their close association with the phenomenon of global warming that threatens the planet.
However, the polar regions play an important role in the global climate system by storing the energy of all the hot zones exist worldwide, and exchanging heat flows from Ecuador against the flow of cold water north and vice versa.
Polar regions, seen also as a factor in regulating the climate of the world, used to study many questions related to the planet such as climate, biodiversity, ozone depletion, atmospheric chemistry, ocean dynamics The structure of the globe, etc.
Our planet appears as a whole when the climate is partly dependent on complex interactions between ocean, atmosphere, biosphere, cryosphere, and human activity. The issue of concern to humanity at present and how to slow the advance of climate change on the entire planet to reduce their impact on living beings.
With the aim of reducing the rapid progress which is the phenomenon of global warming, the optimal use of different energies is needed. Algeria is supported, in turn, and whatever the dangers may be caused to the nature, all efforts by the international community to protect and preserve our planet.
