2. CLIMATE CHANGES Climate change result’s from factors such as the amount of incoming solar radiation or internal factors such as human activity (anthropogenic changes), or the effect of natural factors.

3. CLIMATE changes The causes of climate changes are the subject of intensive research. Another reports of the Intergovernmental Panel on Climate Change (IPCC) clarify the current state of knowledge about the causes of climate change.

5.  The latest report was published in 2007. The IPCC report, a report of the American National Academy of Sciences (NAS), and a report published by the G8 states that most of the observed temperature changes over the last 50 years should be attributed to human activity. In the years 1906-2005 the observed changes in temperature near the Earth's surface amounted to 0.74 ± 0.18 ° C. Between 1990 and 2010 was recorded as 12 hottest years

7.  Greenhouse Gases  The most common factor causing the greenhouse effect is the absorption of infrared radiation by greenhouse gases. These gases absorb the rays reflected from the earth's surface thereby increase the temperature of the troposphere, which leads to an increase in temperature.

8. CLIMATE changes  Aerosols  The hypothesis of a cooling effect of atmospheric aerosols (particulate matter) is related to their properties reflecting solar radiation back into space. For many years it was thought of aerosols (i.e. a particle of sulfates, mineral dusts, sea salt spray) primarily as a reflective particles.
