How much worse was that storm because of climate change?

We know that climate change causes weather to be more extreme, more often. Attribution science tries to nail down exactly by how much.

We’ve been hearing for years that climate change makes weather more extreme, and extreme weather more frequent. But what’s been more difficult to measure is exactly how climate change influences a particular weather event. For example, how much more intense was Hurricane Lala because of climate change? How much more deadly were India’s heat waves this summer? A growing field called attribution science is trying to answer questions like these.

Flora chats with climate scientist Joyce Kimutai about the field and why it's so important. Then, we hear from climate law expert Maxine Burkett about how attribution science could be used in policy, and in the courtroom, to hold emitters responsible.

Guests:

Dr. Joyce Kimutai is a climate scientist specializing in attribution science. She works for the World Weather Attribution Consortium at Imperial College London and is the principal climate scientist for the Kenya Meteorological Services.

Maxine Burkett is a professor of climate, environment, and society at Stanford University in California.

Transcript will be available after the show airs on sciencefriday.com.
