Episode notes
New Discoveries are challenging the idea that "the science is settled" by highlighting that we are still finding massive, primary drivers of Earth's metabolism.
New research shows a 2.4-million-year gravitational cycle between Earth and Mars that affects deep-ocean currents and global warmth. Current Science Suggests that it could have had an impact on our ice ages, when they formed and when they receded. It causes "deep-sea eddies"—massive underwater whirlpools—that keep the deep ocean from becoming stagnant
During the Cambrian period, CO2 was nearly 10 times higher than today. The Earth didn't "die"; it was a "Greenhouse Earth" with no polar ice—which has actually been the planet's "default setting" for 70% of its history.
