global warming

• Cause of global warming

  • heat that gets radiated from the sun goes through the earths atmosphere
  • our atmosphere is made up a whole load of gases included greenhouse gases
  • greenhouse gasses allow trap but allow heat in and builds up the heat of the earth
• Deforestation - global warming

  • less trees to remove CO2 from the atmosphere
  • wasted / not used trees are burnt - releasing CO2 into the atmosphere
  • also wasted / not used trees decay and decomposers that cause them to decay release CO2 while respiring
• Destroying peat bogs

  • peat bogs = soil that hasn't fully decomposed as it s to acidic for decay
  • peat bogs are dried to remove the acidity and can decay
  • decaying - decomposers release CO2 while respiring
  • dried peat released CO2
• Livestock - global warming

  • cows release methane (greenhouse gas)
• Consequences of global warming

  • ice melts
  • sea levels are rising
  • islands (E.g. Madagascar) are sinking
  • birds ( and other organisms) are not migrating this impacts seed dispersal and food chains
  • diseases are spreading due to the hotter temperatures (E.g. Malaria)
  • Temperature of the earth is rising
  • no migration means plants are not be pollinated
