Introduction

Climate change is the global climate variation on the earth. It is due to natural causes as well as anthropogenic actions and they happen in different scales of time and specially climate parameters: temperature, rain, cloud cover, etc. The term "greenhouse effect" refers to the retention of the heat from the sun on the earth's atmosphere; greenhouse gasses prevent heat to be radiated back into space. Without these gasses life as we know it nowadays wouldn't be possible, because the planet would be too cold. Amongst these gasses we find carbon dioxide, nitrous oxide, and methane, released by industries, agriculture, and the burning of coal and the other high global warming potential gasses include hidroflourocarbons, sulphur hexafluoride, and per fluorocarbon, produced by various industrial activities. The industrialized world has ensured that the concentration of these gasses have increased by 30% since the last century when, without anthropogenic actions, nature was responsible for balancing emissions.

At present there is a scientific consensus, almost widespread around the idea that our way of production and consumption of energy is generating a global climate change that would have, in turn, serious impacts both on land and socio-economic systems.

In 1988, an Intergovernmental Panel on Climate Change was created by the World Meteorological Organization and the United Nations Environment Programme (UNEP). This group issued a first assessment report in 1991 which reflected the views of 400 scientists. The report stated that global warming was real and urged the international community that something has to be done about it.

The IPCC reviews worldwide research and issues regular assessment reports and compiles special reports and technical papers. The IPCC's findings, as they reflect global scientific consensus and are apolitical in character, form a useful counterbalance to the often highly charged political debate over what to do about climate change and they played a major role in the negotiations. On the I Working Group about the IV Evaluation Report that came into force on February 2nd 2007,global warming is evident and is attributed to the action of man with a certainty exceeding ninety percent. The average global temperature has risen by 1.8°C to 4.0°C ,also CO2 levels in the atmosphere have increased in the atmosphere a 35.36% since pre-industrial times. A temperature increase of 0.7.4°C occurred last century and for the next two decades, a warming of about 0.2°C per decade is expected if greenhouse gas emissions continue to rise at their current pace and are allowed to double from their pre-industrial level. All of this translates into significant negative impacts on ecosystems and socio-economic systems in all regions of the planet. However, according to the findings of III Working Group taken in Bangkok, Thailand, on May 4th , a decisive action to employ new available technologies to achieve the goal to stabilize at a lower cost than earlier expected. It is imperative to adopt big measures very soon because the solution is within reach of a joint determined willingness.
