Observed and Modelled Global Temperature Growth 1000-2100

Observed and Modelled Global Temperature Growth 1000-2100

 

  • Temperature increase between 1000 and 2100
  • Consistent oscillating trend until 1900 (indirect measurements)
  • Dramatic increase of the world’s temperature after 1900 (direct measurements)
  • Models for projection. From 1.4 to 5.6°C
  • IPCC (Intergovernmental Panel on Climate Change) predicts a reasonable temperature rise of 3-4°C
  • Importance and effects: change in species distribution, population sizes, migration and reproduction times, sometimes frequency of pest and disease outbreak. By the end of the century, climate change and its impacts may be the dominant direct driver of biodiversity loss and changes in ecosystem services globally
  • Predictions set a drastic increase over the century in loss of biodiversity and extinction of several species, water availability will decrease in arid and semi-arid regions, increased risk of floods and droughts, decrease reliability in hydropower and biomass energy production.
