WHAT IS GLOBAL WARMING ??

Increase in the average temperature of the Earth's near-surface air and the oceans.

TEMPERATURE INCREASE

SEA-LEVEL RISE

PREDICTIONS BASED ON PRESENT RATE OF GLOBAL WARMING

üGlobal Mean Temperature Rise of 0.3 °C per decade üNon-uniform temperature rise (greater increase in polar regions) üSea-level rise of 6 cm per decade üNon-uniform increase in rainfall

CLIMATIC CHANGES HURRICANES: Hurricanes are formed in warm water ,if the temperature rises the water will become warmer and more hurricanes will occur.

STORMS: A storm is any disturbed state of an astronomical body's atmosphere, especially affecting its surface, and strongly implying severe weather.

FLOODS: A flood is an overflow of an expanse of water that submerges land, a deluge .

HURRICANES

REASONS ?? üUSE OF CFC üGREENHOUSE GASES CO2--- burning of gasoline. CH4--- rice paddies, bacteria in bogs and fossil fuel manufacture. Nitrous Oxide--- nitric acid production, use of fertilizers. üDEFORESTATION

GREENHOUSE EFFECT

9 WAYS TO COMBAT GLOBAL WARMING 1.) Energy efficiency & conservation. 2.) Alternative energy sources. 3.) Geo-engineering . 4.) Governmental & Intergovernmental control. 5.) Societal control. 6.) Non- Governmental approach. 7.) Mitigation in developing countries. 8.) Population control. 9.) Carbon intensify of fossil fuels.
