An ensemble of climate simulations identifies factors that drove long-term trends of a prehistoric greenhouse climate.
Herbivorous dinosaurs migrated north across Pangea beginning about 214 million years ago, coincident with a downturn in atmospheric carbon dioxide levels.
Volcanic eruptions in what is now western Canada may have triggered a million years of rain and a mass extinction that launched the reign of the dinosaurs.
Largely spared from disruptive tectonic activity, the South African coastline offers a natural setting to study sea levels from when Earth’s atmospheric carbon dioxide last reached today’s levels.
By studying the chemical signatures of 300-million-year-old precipitation, researchers find evidence that the supercontinent Pangea contained peaks as tall as the European Alps.
If this Triassic period delta existed today, its footprint would equal about 1% of all land on Earth.
Earth’s magnetic field waxes and wanes as supercontinents form and break up, suggests a new study postulating a direct connection between our planet’s crust and its core.
