A new study co-led by the Smithsonian and the University of Arizona offers the most detailed glimpse yet of how Earth’s surface temperature has changed over the past 485 million […]
At the end of the Paleocene and beginning of the Eocene epochs, between 59 to 51 million years ago, Earth experienced dramatic warming periods, both gradual periods stretching millions of […]
Oxygenation in the tropical North Pacific Ocean increased during a warm climatic interval that occurred roughly 56 million years ago, despite high global temperatures, according to a new study.
Stars that pass by our Solar System have altered the long-term orbital evolution of planets, including Earth, and by extension modified our climate.
Reconstructions of the paleoclimate indicate that ancient climatic fluctuations on Earth are often correlated with variations in its orbital elements.
