Climate scientist Peter Kalmus breaks down the science of global warming and shares how he transformed his life to reduce his personal emissions.

For many people, there's a disconnect between the trends of global warming and our own actions.

Making changes to reduce our use of fossil fuels can seem daunting, but Peter Kalmus's ability to decrease his emissions by 90% offers proof of what's possible.

Kalmus is a climate scientist who works at NASA's Jet Propulsion Laboratory and holds a Ph.D. in physics from Columbia University.

In Being the Change, published in 2017, Kalmus uses research to demonstrate a clear link between human greenhouse gas emissions and global warming.

Kalmus details the changes we can make to reduce our impact on climate change, sharing his own journey to cutting his emissions and the positive impact it's had on his life.
