4. WHAT IS GLOBAL WARMING?  Global warming relates to the increase in the average temperature of the Earth surface that has been observed in recent years, and it is projected to continue.  It is debated as to whether this is a natural occurrence or whether human activity has impacted or accelerated it. …

5. GREEN HOUSE EFFECT  The greenhouse effect is the process by which absorption and emission of infrared radiation by gases in the atmosphere are purported to warm a planet lower atmosphere and surface.

6. Causes of Global Warming

7. CAUSES OF GLOBAL WARMING! Causes of Global Warming:  Smokes from vehicles and factories.  Throwing garbages anywhere.  Using of CFC’s.  Illegal logging Burning of things.

8. NATURAL CAUSES o Natural causes are causes that are created by nature. o One natural cause is a release of methane gas from arctic tundra and wetlands. o Methane is a greenhouse gas and a very dangerous gas to our environment. o A greenhouse gas is a gas that traps heat in the earth atmosphere. o Another natural cause is that the earth goes through a cycle of climate change. o This climate change usually lasts about 40,000 years.

9. EFFECTS OF GLOBAL WARMING  Climate change  Pollution  Drying of land  Flood Climate change Drying of land

10. EFFECTS OF GLOBAL WARMING Food Pollution

12. OZONE LAYER DEPLETION  The ozone layer protects the Earth from the ultraviolet rays sent down by the sun. If the ozone layer is depleted by human action, the effects on the planet could be catastrophic.  Ozone is a bluish gas that is formed by three atoms of oxygen. The form of oxygen that humans breathe in consists of two oxygen atoms, O2. When found on the surface of the planet, ozone is considered a dangerous pollutant and is one substance responsible for producing the greenhouse effect.

13. Projection of global warming

14. The suggestions reduce Global warming… If we don’t care,who will???

16. Solution of Global Warming  Renewable Energy  Planting Tress  Individual Solution
