Global warming - a gradual increase in the temperature of the Earth's surface caused by the greenhouse effect and causing climate change on a global scale.

Over the last hundred years the average temperature over land has increased by more than half a degree. Scientific opinion is that the average temperature of the Earth has risen by 0,7 ° C.

Much of the warming observed over the past 50 years due to human activities primarily emissions of gases that cause the greenhouse effect.

Global climate change is not limited to warming. There is also a change in the density of the saline oceans, increase humidity, the changing nature of rainfall and melting arctic ice.

In addition to sea level rise increase in global temperatures will also lead to changes in the amount and distribution of rainfall.

The result can pochastishaty natural disasters such as floods, droughts, hurricanes and others.

Some researchers believe that global warming - is a myth, some scholars reject the possibility of human impact on this process.
