The study looked at how different levels of global warming could affect mammal biodiversity. They found that if we exceed the Paris Agreement's limits, there could be a 34% loss of habitat for mammals, putting many species at risk. However, if we stick to the 1.5°C target, the loss could be reduced to 19%, with fewer biomes facing critical levels of habitat loss. This shows that taking action to limit global warming is crucial for protecting mammal biodiversity.
