There will probably be no more land mammals in 250 million years when landmasses join together again.
in Nature Geoscience explained that the world is only a couple hundred million years away from creating a new supercontinent. Researchers used data on continental movements to create a new future map. The scientists also used information about what chemical fluctuations in the atmosphere will look like in the future to create a range of different atmospheric and geological conditions on what they’re calling Pangea Ultima.
world where our bodies’ natural mechanisms won’t work. This is because tectonic movements would create more volcanic eruptions in the future, spewing more carbon dioxide into the atmosphere which will trap more heat on the planet.could rise from around 400 parts per million today to more than 600 ppm many millions of years in the future,” Eunice Lo, a research fellow in climate change and health at the University of Bristol and study author, said.
The sun is also expected to become hotter and stronger a few hundred million years in the future. Aroundesearchers estimated that the sun is likely to emit about 2.5% more radiation . “Widespread temperatures of between 40 to 50 degrees Celsius, and even greater daily extremes, compounded by high levels of humidity would ultimately seal our fate,” Farnsworth said. Most mammals and future humans will expire in what could be permanent 100 degrees Fahrenheit heat.This means that Pangea Ultima’s coasts are likely to be even more humid than our coastal regions are today, and the vast inland will turn into a large desert.
steady food supply for any human civilization that exists that far out into the future, and for other mammals.scenario is well into the future, our planet is currently stressing society and animal environments. Climate change caused by burning fossil fuels has warmed our ambient air temperatures at unnaturally fast rates in the last few decades.
