Limiting global warming to 1.5°C rather than 3°C avoids 60% of the increased human exposure to drought. Crop yield loss is reduced by half

Limiting global warming to 1.5°C allows most biodiversity to persist in refugia. At 3°C warming, 65% of natural areas lose half their species and two thirds of pollination services.
