description: "Number of heatwave days per year calculated following the definition\
  \ of the South African Weather Service, where the maximum temperature at a particular\
  \ town is expected to meet or exceed 5 degrees C above the average maximum temperature\
  \ of \u201Cthe hottest month\u201D for that particular place, as well as persisting\
  \ in that mode for 3 days or more. The baseline is calculated for 2001\u20132020,\
  \ with projections for 2021\u20132040 and 2041\u20132060 under two climate scenarios:\
  \ RCP 4.5 (moderate emissions) and RCP 8.5 (high emissions)."
