I’m a researcher at the British Antarctic Survey and an adjunct professor at the University of Toronto. I study what lakes in polar regions tell us about past and present climate.

Rage Against the Miocene.

(I love the Miocene, but we're not prepared to live in it!)
For the first time ever, recorded atmospheric CO₂ has exceeded 430ppm! The last time CO₂ consistently reached today’s human-driven levels was ∼14 Million years ago, with shorter periods of similar levels around 3-5 Million years ago.
