Lately, the global warming became a topic in various media, the public is worried about what will happen to our planet.
As the name implies, global warming is the rise in global temperatures, generating serious complications such as hurricanes, droughts, floods, extinction of thousands of animal and plant, melting poles and other problems that man is unable to cope or control.
Many years ago, man destroys the planet and the researchers warn about the serious consequences of these acts.
There is ample evidence that the planet's temperature has increased: thermometers rose 0.6 ° C since the mid-nineteenth century, sea levels also rose and glacial regions of the planet are shrinking. Scientists also consider evidence of global warming, the temperature difference between the land surface and the troposphere (nearest atmospheric soil zone).
Most climate scientists believe that increasing the amount of greenhouse gases (carbon dioxide, methane, etc) into the atmosphere causes a rise in temperature, greenhouse gas emissions (resulting from deforestation and burning of fossil fuels) can become a barrier that the heat spreads increasing the earth's temperature. (see Greenhouse Effect).
The most responsible for greenhouse gas emissions are the United States (which topped the list with about 36% of the world total), the European Union, China, Russia, Japan and India.
The IPCC (Intergovernmental Panel on Climate Change) created by the UN, has gained prominence because of its expected reports on the causes of this immense problem and also for pointing out some ways to reverse the situation.
In 2005, entered into force the Kyoto Protocolode that includes the participation of hundreds of nations that have pledged to reduce greenhouse gas emissions in the atmosphere; however, the United States has not signed the agreement.
Climate scientists warn that the consequences of global warming will have immense dimensions, most of them predicts a shortage of drinking water, changes in the conditions of food production and increase in the number of deaths caused by various disasters (floods, heat, drought, etc.) besides the rising sea level and the extinction of various animal and plant species.
Probably the most affected will be those nations that do not have many conditions to combat this problem, because they have no financial, technological and scientific resources.
