If you would like to send me an invitation, a time-sensitive comment, or a request, please do so here. This form goes to my wonderful assistant Laura, who is able to respond much more quickly to email than I can.

If you have a question, please see the many I’ve already answered our FAQ page, our Global Weirding episodes, and Quora before you use this contact form to send an email.

If you want me to endorse, sign, or review a book, a letter, a petition, a study or a similar product, I’m sorry I am typically unable to do so. Please read my review policy before you use this contact form to send an email.

If your comment relates to Twitter, please tag me in a tweet or comment there. I’m only able to take Twitter-related requests on the platform itself.

If you’re wondering where I’ll be speaking next, we have a lot of online events, which means you can attend from anywhere in the world! I currently post these on Facebook and Twitter; I let the calendar on this page lapse over the pandemic but am hoping to re-populate it soon.

Many of my public talks have been recorded; I have over a hundred lectures and webinars archived here and our Global Weirding series has over 30 episodes that are available to be viewed and streamed, no permission needed.

If you aren’t in any of these locations, I’m always open to suggestions. Because my air travel is the largest part of my carbon footprint, though, I usually schedule multiple events in the same location – anywhere from five or six to more than two dozen in a week. This takes a lot of coordination, so we generally collect invitations and book in-person events 12-18 months in advance. However, I’m happy to do a carbon-neutral video presentation on shorter notice. Requests for presentations that are either virtual or in Texas are currently booking for Spring 2023.

Last summer, I assumed the position of Chief Scientist for The Nature Conservancy and in the fall I released a book, Saving Us: A Climate Scientist’s Case for Hope and Healing in a Divided World. For this reason, my virtual presentations, webinars, and podcasts for 2022 are limited to TNC- and book-related events only. If you would like a presentation on a different topic, I encourage you to use one of my many talks archived here; no permission needed. Thank you!
