Human Extinction by 2030

climate interaction

Increased inflow of warm water from the North Atlantic into the Arctic Ocean can cause methane to erupt from the seafloor of the Arctic Ocean.

Methane releases from the seafloor of the Arctic Ocean have the potential to rapidly and strongly accelerate warming in the Arctic and speed up further feedbacks, raising global temperature with catastrophic consequences in a matter of years.

Altogether, these feedbacks and further warming elements could trigger a huge abrupt rise in global temperature making that extinction of many species, including humans, could be less than one decade away.

In many respects, we are already in the sixth mass extinction of Earth’s history. Up to 96% of all marine species and 70% of terrestrial vertebrate species became extinct when temperatures rose by 8°C (14°F) during the Permian-Triassic extinction, or the Great Dying, 252 million years ago.

During the Palaeocene–Eocene Thermal Maximum (PETM), which occurred 55 million years ago, global temperatures rose as rapidly as by 5°C in ~13 years, according to a study by Wright et al.

A recent study by researchers led by Zebe concludes that the present anthropogenic carbon release rate is unprecedented during the past 66 million years.
