Study pairs sea-surface temperatures with levels of atmospheric CO2 during hyperthermals.

Researchers used sediment cores taken from bottom of the Pacific Ocean that contained shells formed by ancient microscopic creatures who once lived near the surface.

The total amount of carbon released during these periods was similar to the range projected for ongoing and future human emissions.

Fossilized shells of foraminifera, single-cell. shell-building plankton.

Shells accumulate small amounts of the element boron, which reflect CO2 levels in the ocean at the time.

The cores were extracted from the Shatsky Rise , an underwater plateau in the subtropical North Pacific east of Japan .
