Climate change impacts on the amazon rainforest

• • When forests are burnt and cleared between 30 and 60 percent of the carbon is released into the atmosphere
  • The likelihood of forest fires increase when the forest is drier
  • When forests burn carbon dioxide is released this is a greenhouse gas which will amplify the effects of climate change leading to an increase in global temperatures
• • Plants and animals living in tropical rainforests adapted to moist conditions, may die in dry weather.
  • Frequent or long periods of drought could lead to extinction of some species, and forest fires which can destroy large areas,
  • releasing lots of carbon dioxide and causing positive feedback.
• • Scientists predict a 4 degree rise could kill 85% of the Amazon rainforest,
  • resulting in an increase in the amount of carbon released
  • as there is an increase in the rate of decomposition , and less carbon dioxide taken in through photosynthesis.
• What degree rise could kill 85 percent of the amazon rainforest?

  4
• A 4 degree rise would kill how much of the amazon rainforest?

  85 percent
• A 4 degree rise in the amazon rainforest would increase the rate of what?

  decompostition
• When there is an increase in the rate of decomposition more of what is released?

  carbon dioxide and methane
