• Greenhouse gases like
CO2 and H2O form a
blanket above the earth
surface.
• They trap the solar
heat.
...
This leads to :
• More drought
• more flooding
• less ice and snow
• extreme weather
• rising sea level

Climate change

  1. 1. BY: NISHITA BANERJEE VI C
  2. 2. WHAT IS CLIMATE? • Climate is the general weather conditions of a place. • It is the pattern of variation in temperature, humidity, atmospheric pressure, wind, precipitation etc.
  3. 3. • Climate of the world is changing at a rapid speed. • Changes in climate can be: changes in average temperature changes in rainfall patterns changes in humidity level of a place.
  4. 4. CHANGING CLIMATES HAVE CHANGED LANDSCAPES ARAVALLI HILL FORESTS, INDIA
  5. 5. CHANGES IN THE FOLLOWING CAUSE CLIMATE CHANGE: CHANGE • Sun’s output • Earth’s orbit • Drifting continents • Volcanic eruptions • Greenhouse gases
  6. 6. SOLAR OUTPUT CAUSES ONLY MINOR CHANGES IN EARTH’S TEMPERATURES.
  7. 7. • In the distant past, these made a big difference in climate over millions of years by : changing ice caps at the poles altering ocean currents, which transport heat and cold .
  8. 8. CONTINENTAL DRIFT
  9. 9. Huge volcanic eruptions can cool Earth by injecting ash and tiny particles into the stratosphere
  10. 10. COOLING EFFECT AFTER VOLCANIC ERUPTION
