If only people could have been more careful & less selfish & greedy!
🚨 It's official. Earth will be over 158°F (70°C) and completely unlivable.
As we've long known, a new supercontinent is forming on Earth.
And a supercomputer-driven study shows that when this happens, no mammals will survive.
In around 250 million years, Earth will once again be home to a single supercontinent—Pangea Ultima. But this massive landmass, coupled with a hotter Sun and elevated carbon dioxide levels, will create a planet too hostile for most life, including humans.
Temperatures could soar up to 70°C (158°F), and extreme humidity will make it impossible for mammals to regulate body heat.
Inland regions, far from moderating coastlines, would be especially brutal due to the “continentality effect,” creating vast deserts devoid of food and water.
What’s more alarming is that these projections are based on the assumption that fossil fuel burning will eventually stop. If emissions continue unchecked, those dangerous carbon dioxide levels could arrive much sooner than millions of years from now.
While this study offers a dramatic view of Earth’s long-term climate trajectory, the authors emphasize its immediate relevance. Current global warming is already producing deadly heat, and the study serves as a stark reminder of what lies ahead if greenhouse gas emissions aren't curbed. The clock is ticking—not just for the distant future, but for the present.
