Because as long as greenhouse gas emissions do not slow, the Azores will continue to expand.
The problem is that winter rains are particularly important to the environmental and economic health of Portugal and Spain. Without it, viable areas for viticulture could disappear, for example, almost completely by 2050. Olive production could drop by 30% by 2100.
