What really killed the dinosaurs? (It wasn’t just the asteroid) - Sean P. S. Gulick
Let’s Begin…
Sixty-six million years ago, near what’s now the Yucatán Peninsula, a juvenile sauropod feasted on horsetail plants on a riverbank. Earth was a tropical planet. Behemoth and tiny dinosaurs alike soared its skies and roamed its lands while reptiles and tentacled ammonites swept its seas. But, in an instant, everything would change. Sean P. S. Gulick details one of Earth's most devastating periods.
Modern day global climate change is also referred to as global warming. Explain what is primarily causing today’s climate change in comparison to what primarily caused global cooling during the extinction of the dinosaurs? (Hint: How did the asteroid impact change climate?)
