Scientists make shocking ‘triple whammy extinction event’ prediction set to hit Earth

A new scientific study suggests it has pinpointed when all life on Earth will eventually disappear. According to the research, every species on the planet will someday vanish, with even humanity’s greatest achievements fading into dust.

Unlike the asteroid that wiped out the dinosaurs, this future extinction won’t be triggered by a single catastrophic strike. Instead, researchers say Earth will face a deadly combination of three environmental crises that will make the planet impossible for living creatures to survive.

The study, published in Nature Geoscience and powered by supercomputer simulations, predicts that life is safe for now—but only for a few hundred million years. The researchers estimate that mammals will be eradicated in roughly 250 million years.

They explain that the first crisis will occur when Earth’s continents merge into a new supercontinent, known as “Pangaea Ultima,” formed through the slow movement of tectonic plates. This process is expected to unleash intense volcanic activity and massive releases of heat-trapping gases.

These greenhouse emissions could push global temperatures to between 40°C and 50°C—far worse than the warming caused by burning all remaining fossil fuels. According to the scientists, mammals would not be able to survive such extreme heat.

After this scorching phase, Earth could swing to the opposite extreme. Historical patterns show that supercontinent formation can trigger drastic cooling, creating temperatures cold enough to cause ischemic necrosis, a fatal condition caused by severe blood vessel constriction.

These extreme heat waves, deep freezes, and rising atmospheric CO₂ create the “triple whammy” that would eliminate life. Despite the distant timeline, researchers stress that today’s human-driven climate change remains an urgent threat, underscoring the need for rapid emissions cuts.
