Global warming to earth

1. Global Warming

2. What is Global Warming?
• Global warming is the gradual increase in the overall
temperature of the earth's atmosphere generally
attributed to the greenhouse effect caused by
increased levels of carbon dioxide,
chlorofluorocarbons, and other pollutants.

3. What are the main causes global
warming?
•Natural
•Man-made

4. • Climate change
•Volcanoes
•Change in ocean currents
•Rotation of the earth
•Solar cycles and sunspots
Natural

5. Man-made
•Deforestation
•Power plants
•Ozone depletion
•Fossil fuels
•Improper waste disposal

6. Greenhouse effect
• The greenhouse effect is the process by which
radiation from a planet's atmosphere warms the
planet's surface to a temperature above what it would
be without this atmosphere. Radiatively active gases
in a planet's atmosphere radiate energy in all
directions.

7. Greenhouse effect
•the trapping of the sun's warmth in a planet's lower
atmosphere, due to the greater transparency of the
atmosphere to visible radiation from the sun than to
infrared radiation emitted from the planet's surface.
