Intergovernmental Panel on Climate Change (IPCC)

  • Changes in the state of climate can be identified by the changes in the mean and/or variability of its properties, persists for an extended period
  • Humans are the “dominant cause” – due to our GHG emissions- mainly CO2
  • Top ten hottest years on record from 1998, 2010 was the hottest
  • Impacts from recent climate related extremes, such as heat waves, droughts, floods, cyclones and wildfires, reveal significant vulnerability and exposure of some ecosystems and many human systems…’
  • “Severe, pervasive and irreversible“ impacts if no action is  taken. Over 100 million people will die by 2030 and 90% of this will come from developing countries.
  • Adaptation and mitigation choices in the near term will affect the risks of climate change throughout the 21st century
