Why is the content of this map important?
An increase in precipitation is detrimental to tourism. On the other hand, freshwater resources are critical on small islands.
Which sectors are affected by this result?
This result will impact the tourism sector, and potentially fisheries in some capacity as well.
What is shown on the maps?
Under present climate conditions, annual precipitation is about 1500 mm across the region. The precipitation increase is less homogeneous, ranging from 300 mm in the North and the South of the domain, to 500 mm in the middle. This is a huge increase, and the 3 models agree on this. At the +3°C scenario, this increase is further enhanced and extends mainly towards the North of the region.
Details and further information:
The table below shows that precipitation increases by 50% in January-February (dry period) and in July-August (wet period) for +2°C.
