Over recent years, concern about a coming hothouse mass extinction set off by human carbon emissions has been on the rise. Studies of Earth’s deep history reveal that at least 4 out of the 5 major mass extinctions occurred during both hothouse periods and during times when atmospheric and oceanic carbon spiked to much higher than normal ranges. Now a new scientific study reveals that we are have already emitted 50 percent of the carbon needed to set off such a major global catastrophe.

Fossil Fuel Burning = Race Toward a 6th Mass Extinction

The primary driver of these events is rising atmospheric CO2 levels — often caused in the past by the emergence of masses of volcanoes or large flood basalt provinces (LIP in image below). In the case of the worst mass extinction — the Permian — the Siberian flood basalts were thought to have injected magma…
