A Pocket Guide for Scientists: What to Expect When You’re an Expert Witness, Part 1

What to Expect When You're an Expert Witness, Part 1

As the impacts of climate change become more apparent, various parties are using litigation to push lawmakers to address mitigation and adaptation strategies, and attempt to hold fossil fuel producers liable for climate-related damage. As such cases progress and multiply, there will be an increasing demand for climate scientists and scientists with relevant training to serve as expert witnesses to assist judges and juries in understanding the science underlying these arguments.

These developments present an exciting opportunity for climate scientists to participate in the legal process. However, it is important for a scientist considering serving as an expert witness to understand what the process involves.

This guide helps scientists know what to expect when serving as an expert witness. To learn more about the risks of participating, and how to mitigate them, see the second guide in this series: “What to Expect When You’re an Expert Witness, Part II: Risks and How to Avoid Common Pitfalls.”
