Name: Preserve the Polar Regions and Glaciers
Date of Issue: 28 March 2009
Over the millennia, glaciers have experienced phases of growth and melting of their mass, as is the natural fluctuation dictated by the climatic cycles. Since the last decades, they have begun the decline that continues today.
As the ice melts, there is less and less solar energy is reflected by the ice and more absorbed by the ocean.
A considerable reduction of glaciers and ice covering the sea in the Polar Regions has been registered. Thus, the thickness of the ice in the Arctic Ocean has increased from 4.88 m on average in 1980 to 2.75 m in 2000, a decrease of 2.13 m in 20 years. According to studies carried out during 2003 by the National Aeronautics and Space Administration (NASA), the Arctic is losing about 10% of its permanent ice.
Over the past century, temperatures in the northern regions has increased an average of 1.51 ° C, resulting in the phenomenon of global warming, a phenomenon linked primarily to the concentration of greenhouse gases in the atmosphere. The greatest increase in temperature during this century range from 2 ° C and 6 ° C and affect primarily the northern regions of the planet. Also, methods of production of various energies have clearly demonstrated their close association with the phenomenon of global warming threatening the planet.
However, the Polar Regions play an important role in the global climate system by storing the energy of all the existing hot zones around the world, and exchanging heat flows from Ecuador against the flow of cold water north and vice versa.
The polar regions, considered as a factor regulating the climate of the world, enable us to study many questions related to the planet such as climate, biodiversity, the ozone hole, atmospheric chemistry, ocean dynamics The structure of the globe, etc..
Our planet appears as a whole where the climate partly depends on complex interactions between ocean, atmosphere, biosphere, cryosphere and human activities. The issue of concern to humanity at present and how can slow the advance of climate change on the entire planet in order to reduce their impact on living beings.
With the goal of reducing the progress that is rapid phenomenon of global warming, the optimal use of different energies is needed. Algeria, however, and whatever the dangers may be caused to the nature, all efforts by the international community to protect and safeguard our planet.
