Project workon Global Warming
Global warming - the gradual increase in the average temperature of Earth's atmosphere and the position of the Intergovernmental Panel on Climate Change. Is that the average temperature on Earth has risen by zero point seven degrees Celsius since the Industrial Revolution.

Effects of global warming
In addition to sea level rise, global temperature rise will also lead to changes in the amount and distribution of precipitation. This can result in more frequent natural disasters: floods, droughts, hurricanes and others. Warming should, in all probability, increase the frequency and magnitude of such phenomena.

Causes of global warming
Climate system change as a result of natural internal processes or in response to external stimuli (anthropogenic and non-anthropogenic).
The reasons for such climate change remain unclear, but among the main external influences - change the Earth's orbit, solar activity, volcanic emissions and the greenhouse effect.
Emissions of greenhouse gases
This is a process in which the absorption and emission of infrared radiation heats the atmospheric gas atmosphere and the surface.
Carbon emissions into the atmosphere from burning fossil fuels from 1800 to 2007, in billions of tons.

Prevention of global warming
Broad consensus among climate scientists regarding the continued growth in global temperatures has led to the fact that a number of states, corporations and individuals trying to prevent global warming or to adapt to it. To date, the main international agreement on combating global warming is the Kyoto Protocol.
The Kyoto Protocol
Kyoto Protocol - an international agreement adopted in Kyoto (Japan) in addition to the UN Framework Convention on Climate Change. It commits developed countries and countries with economies in transition to reduce or stabilize greenhouse gas emissions.
