“The exciting part is learning how linked the Earth system is, and how one change can unlock several others.”
We thought the first climate mass extinction was simple: an ice age wiped life out.
Then we noticed something that doesn’t fit: it happened in two pulses.
So what delivered those two blows?

Evolution doesn’t always move forward. Sometimes it stops, resets, and rebuilds.
A 445-million-year-old extinction changed the course of vertebrate life, and we’re only now seeing how.

Climate change isn't just a story of the carbon cycle, other elemental budgets are also affected and interact. The nitrogen cycle is also affected by elevated CO2 concentrations, warming, and altered precipitation regimes. 🧪
