Climate Data Projections

According to the USAID Climate Risk Profile, key future climate trends include:


  • The annual mean temperature is projected to increase in much of the Amazon by 1.7˚C to 5.3˚C by 2085.
  • The duration of heat waves in much of the Amazon is projected to increase by 18 to 214 days by 2085.


  • The dry season in the Amazon will likely get longer and there will likely be decreased precipitation, especially during the dry season.
  • Droughts in the Amazon will increase as ENSO events become stronger and more frequent in the future.
  • The tropical wet region is projected to have a significant increase in dry spells, from a decrease of 5 dry days to an increase of 19 days, depending on the model.

This section provides the options to visualize climate variables and indices derived from scientifically vetted CMIP5 projections for different timeframes, statistics, emission scenarios, and climate models.
