As many as five billion people will face hunger and a lack of clean water by 2050 as the warming climate disrupts pollination, freshwater, and coastal habitats, according to new research published last week in Science. People living in South Asia and Africa will bear the worst of it.

Climate activists have been telling us for a while now that global warming isn’t just about the polar bears, so it’s hardly breaking news that humans are going to suffer because nature is suffering. But what is new about this model is the degree of geographic specificity. It pinpoints the places where projected environmental losses overlap with human populations who depend on those resources and maps them with a nifty interactive viewer.

This model identifies not just the general ways climate change harms the environment and how people will feel those changes, but also where these changes will likely occur, and how significant they’ll be. It’s an unprecedented degree of detail for a global biodiversity model.

Patricia Balvanera, a professor of biodiversity at National University of Mexico who wasn’t involved in the study, said the new model “provides an extremely important tool to inform policy decisions and shape responses.”
