Transcript of Global Warming

Global warming is the rising phenomenon of the surface temperature of the planet, with particular reference to the Earth's atmosphere and the oceans. The main cause of this phenomenon are the human activities that generate pollution.
What is it?
At this rhythm the temperature growth in the next years could be 0.2 degrees per decade, and perhaps more, and reach between 1.8 and 4 degrees of global rise at the end of the twenty-first century. This could cause the extinction of many animal and plant species. This phenomenon is also changing the distribution of rainfall and pushing the animals to move. Polar bears need the ice to hunt and accumulate the fat needed to overcome the months when food is scarce. The bears are forced to prolong the months of fasting. Less healthy bears have a low reproductive rate, increasing the chances of extinction.
The Damages
The sea levels could rise between 18 and 59 centimeters by the end of the century. A rise of just 10 cm would flood many of the South Sea islands.
In the United States, they are at risk especially Louisiana and Florida.
The effects and consequences
The Kyoto Protocol is an international agreement to combat global warming which went into effect February 16, 2005. The Kyoto Protocol committed the underwriters countries to a quantitative reduction of their greenhouse gas emissions.

Global Warming
CO2 levels increase from the time of the Industrial Revolution (during the 1800s), and temperatures also began to increase with the increase of carbon dioxide (due to the use of fossil fuels such as coal, oil and derivatives)..
