Future Supercontinent Predicted to Create Deadly Climate for Mammals

Scientists predict a supercontinent will form in about 250 million years, leading to extreme global warming.
Increased solar radiation, volcanic activity, and atmospheric carbon will contribute to inhospitable temperatures.
Climate models show large regions could average 104°F to 122°F, threatening mammal survival.
Only small portions of the coasts may remain habitable for mammals like humans.
The research underscores the need to curb emissions now to avoid current climate change impacts.
