Global warming in figures

Global warming is the increase of the average temperatures recorded in the atmosphere, near the ground and the oceans. Global warming was first mentioned 60 years ago, following massive industrial development and the increase in greenhouse gases that are largely considered responsible for this phenomenon. The increase of CO2 in the Earth atmosphere is very low around 0,1 %, but it is more than enough to unbalance the planet's fragile climate and start a possible global warming. The main cause of global warming is increasing the concentration of CO2 in the atmosphere in the last centuries. It was 280 ppm before the industrial revolution, is now 430 ppm, or nearly double, and in 2035 would be 550 ppm, if the flow of current emissions of greenhouse gases (GHG) emissions would persist over natural capacity for absorption.
This could result in the immediate period to global warming up to 2 ° C. This is likely to happen if we consider the rapid developing economies in China, India, Brazil, Australia, and Southeast Asia or in Eastern Europe and the fact that the U.S. has not ratified the Kyoto Protocol. This protocol stated the use of substitute renewable energy sources cleaner instead of fossil fuel, things that will help us fight global warming.

Climate models developed by climatology experts estimate that the global climate will warm by 1.1 to 6.4 ° C during the 21st century. Global warming estimates vary so much because of the rapid evolution of human kind. This way the gas emissions can not be predicted  with accuracy. Moreover, the tendency showing the continuous heating of the planet in the XXI century is revealed by many studies in the field. Very dramatic is that global warming makes these climate scenarios possible and that the polar areas will warm the most, which could have dramatic consequences with the melting of the ice caps.
Since the industrial explosion in the 19 century and every since meteorological records have been kept it has been noticed a noticeable change in the climate identified with the raise of Earth medium temperature, our days so called global warming. We have to take serious the global warming of our planet before it's too late. In the last 100 years the medium temperature raised with 0,74 Celsius degrees which determined the start of glacier's melting.
