Exact excerpt

We show that natural nitrogen fixation in the tropical Atlantic was significantly reduced during the warm late Pliocene and then increased into the cooler Pleistocene. ... After large Northern Hemisphere ice sheets began to grow at the end of the Pliocene, about 2.8 million years ago, nitrogen fixation in the Caribbean rose and fell in synchronization with the approximately 41,000-year Milanković cycle in the tilt of Earth's axis.
