Our environment is changing.
We are scientists investigating the physics and chemistry of the environment. We use stable isotopes as our primary tool, exploiting natural variations in their abundances to unravel its inner workings, how it is changing, and what it was like in the past. We focus on the atmosphere and the oceans, but our research spans a range of time and space: from microseconds to millennia, and from molecules all the way to the big blue marble.
