I'm a freelance writer and contributing editor for Scientific American. As an editor, I have helped dozens of scientist-authors translate their jargon for the public. My heart lies with Earth history, but I stray frequently to write about ocean policy, climate change and the environment. My home base is sunny Riverside, CA. Contact: simpson@nasw.org.
