Climate Change

Climate Change

1. Effects

   • Stronger Storms
   • Thawing Permafrost
   • Warmer Oceans
   • Rising Sea Level
   • Damaged Corals
   • More droughts and Wildfires
   • Higher Temperatures and More Heat Waves
   • Changes is Plant Life cycles
   • Changing rain and snow patterns
   • Less Snow and Ice

2. Changes AIR & OCEAN CURRENTS which changes WEATHER PATTERNS

   • Where do the Greenhouse gasses come from?
     • Man - made
       • >Carbon Dioxide - Burning fossil fuels; oil gas & coal
       • >Sulphur Dioxide - Burning fossil fuels; oil gas & coal
       • >Nitrous Oxide - Electricity production
       • >Methane - Rubbish decomposition. Domestic animal production. Flatulence and Burping!
     • Natural
       • >Carbon Dioxide - Respiration, Breathing, Bush Fires, Volcanoes
       • >Sulphur Dioxide - Volcanoes
       • Nitrous Oxide - Lightning, Bacteria in soil
       • >Methane - Decomposition of organic matter. Flatulence!

3. Greenhouse Effect

   • 1. Solar energy from sun passes through atmosphere
   • 2. Same energy is reflected back out into space
   • 3. Earth's surface - heated by sun and radiates heat back out towards space
   • 4. GREENHOUSE gasses in the atmosphere trap in some of the heat
   • The atmosphere around earth like a giant greenhouse - traps in heat to stop earth from freezing
     • This is a natural process that keeps the planet warm & sustains life (keeps it alive).
     • The planet is warming due to this and the pollution we put into the air around us.

4. Global warming

   • This happens because of the greenhouse gasses
     • The gasses in the atmosphere are: >Carbon Dioxide >Sulphur Dioxide >Nitrous Oxide >Methane
   • Effects
     • >Extreme Weather
     • >Drought
     • >Flooding
     • Polar Ice Caps Melting
     • Sea Levels Rising
     • >Species Extinction
     • Food Shortages

5. More Effects

   • Good
     • Better food production
     • More food produced
     • Longer growing seasons
   • Bad
     • No Snow for skiers
     • Farmland lost
     • More pests and disease for farmers
     • Cities under threat
     • Land flooded
     • High cost of sea defences
   • In the middle
     • Mediterranean Summers
