Слайд 1
Change in the weather and climate in the world
Слайд 2
Changing weather and climate are variations in the Earth's climate as a whole or of its separate regions with the passage of time, resulting in a statistically reliable deviations of parameters of weather from the multiyear averages for the period of time from decades to millions of years. 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.
Слайд 3
Factors of climate changes are caused by changes in the earth's atmosphere, the processes occurring in other parts of the 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.

Слайд 12
Climate impact of all factors, both natural and anthropogenic, is a single value - radioactive heating of the atmosphere in 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.
