The quintessential ice cream flavour is under threat, and many other dessert staples along with it, according to climate change researchers at the University of Costa Rica and Belgium's KU Leuven university. Increasing climate extremes are changing the habitats of wild vanilla species — primarily found in the tropical regions of Central America — and their mainly animal pollinators, the researchers say. This, in turn, is putting global production of vanilla at risk. In some regions, the plants may find more favourable conditions, but the insects that pollinate them may no longer find suitable habitats, according to the study published...
