Published on 18 September 2026, the study places the release around 183 million years ago. One petagram is one billion tonnes, so the estimate equals roughly 18 trillion tonnes of carbon.<\/p>\n

Researchers assimilated global carbon-isotope and atmospheric CO2 records into an Earth-system model. The figure therefore depends on geological dating, proxy interpretation and model structure.<\/p>\n

Source of the carbon<\/h2>\n

The simulations favour predominantly magmatic carbon, while allowing thermogenic or biological carbon at the event\u2019s onset.<\/p>\n

Recovery<\/h2>\n

At least 6,800 Pg of organic carbon burial and about 6,000 Pg C of excess consumption through silicate weathering helped the climate system recover over geological time.<\/p>\n

\"About
This AI-generated image explains the topic; it is not a photograph of an actual event, observation or field site.<\/figcaption><\/figure>\n

Why it matters<\/h2>\n

The work links the size and source of the pulse with two recovery pathways rather than treating the warming interval as a single unexplained spike.<\/p>\n

Limits<\/h2>\n

Continents, ecosystems and timescales differed sharply from today. A large ancient total does not directly describe the rate or impacts of modern emissions.<\/p>\n

Next check<\/h2>\n

Tighter dates from other sections and independent model runs must test the timing of carbon input, oxygen loss and recovery.<\/p>\n

A reconstruction of the Toarcian oceanic anoxic event estimates that about 18,000 petagrams of carbon, mostly magmatic, were released.
