Scientists determine the timing and duration of a major hyperthermal event in the Early Jurassic

Using high-precision dating of geologic regions, scientists have found evidence that one of the most significant warming spikes of the last 500 million years had a surprisingly short duration, about 300,000 years. And it coincides with a carbon event that was half a million years after an earlier igneous episode than had been thought to cause the hyperthermal spike. Their work has been published in the journal Geology. Using high-precision dating of geologic regions, scientists have found evidence that one of the most significant warming spikes of the last 500 million years had a surprisingly short duration, about 300,000 years.
