A study of boron/calcium ratios in the shells of marine plankton suggests that the Paleocene-Eocene Thermal Maximum, a rapid global warming and ocean acidification event 55.6 million years ago that ...

56 million years ago, the Earth experienced one of the largest and most rapid climate warming events in its history: the Paleocene-Eocene Thermal Maximum (PETM), which has similarities to current and ...

Jim Zachos holds a sediment core from the seafloor showing the red clay layer that marks the Paleocene-Eocene Thermal Maximum (PETM), a period of extreme global warming and ocean acidification around ...

Reconstructed surface air temperature (left) and rainfall amount (right) during the Paleocene-Eocene Thermal Maximum warming event, 56 million years ago. The maps were created by blending geological ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Body size plays a critical role in mammalian ecology and physiology. Previous research has shown that many mammals became smaller during the Paleocene-Eocene Thermal Maximum (PETM), but the timing and ...

This study is led by Wang Xueting, Dr. Wang Xu, and Dr. Chen Zuoling from the State Key Laboratory of Lithospheric and Environmental Coevolution, Institute of Geology and Geophysics, Chinese Academy ...

The Paleocene-Eocene Thermal Maximum, or PETM, was a short interval of highly elevated global temperatures 56 million years ago that is frequently described as the best ancient analog for present-day ...
