Mammals could face mass extinction as Pangea Ultima forms

Around 200 million years from now, the world's continents are expected to merge into a single landmass known as Pangea Ultima. During this time, global temperatures may climb to between 40°C and 70°C, turning 90% of the land into scorching desert. The combination of rising solar brightness and increased carbon dioxide levels from volcanic eruptions will likely exceed the heat tolerance of mammals, which could lead to the total extinction of the species.
