Take into account changes as the average values of weather parameters, and changes in the frequency of extreme weather events. The study of climate change engaged in science paleoclimatology.

world, such as the oceans, glaciers, as well as the effects associated with human activities. External processes that shape the climate are the changes of the solar radiation and the Earth's orbit.

W/m2. Volcanoes, glaciers, continental drift and drift of the Earth's poles are powerful natural processes affecting the Earth's climate. In the scale of several years volcanoes can play a major role. As a result of the eruption of the volcano Pinatubo in 1991 in the Philippines to a height of 35 km been abandoned so much ash that the average level of solar radiation decreased by 2.5 W/m2. However, these changes are not long term, the particles relatively quickly settle down. In the scale of thousands of years determining the climate of the process will be, probably, the slow movement from one of the glacial period to the next.
