If you would like to send me a comment or request an interview, 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 on the science – like, how do we know carbon dioxide is a heat-trapping gas? isn’t this warming just a natural cycle? or aren’t there more polar bears today than fifty years ago? – we’ve collected all our most frequently asked questions, and turned them into super-short Global Weirding episodes. If we haven’t gotten to your question yet, please review Skeptical Science’s helpful answers, to see if they’ve already tackled it. They do a great job.

If you’re wondering whether I could speak to your group, please check out Climate Voices first. It is a free speaker’s bureau featuring over 200 scientists from around the U.S. I know many of them personally and can’t recommend this resource strongly enough, because the value of connecting with a local scientist who lives just down the road from you is … well, priceless!

If you really want me, check my list of events and see if I already have something planned for your area. In January 2019, I’m in San Francisco and the LA area as well as giving a virtual colloquium at Arizona State University; in February, I’m in DC and Rutgers. Indiana in late March, Wisconsin, Colorado, Oklahoma and Dallas in April, and England in May. In July and September, I’ll be in Toronto and Sept I’ll also be visiting Alaska (Fairbanks, Anchorage and Juneau), then UC Berkeley and Stanford the beginning of November. March 2020 will be Scotland and Ireland, and we’re in the beginning stages of planning trips to Alabama, Atlanta and southern Virginia and open to more events to add there.

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 three or four to my record of 25 in one week! This takes a lot of coordination, so we generally collect invitations and book 12-18 months in advance. However, I’m happy to do a carbon-neutral video presentation on shorter notice and am much more available for those. So even if you haven’t done one before, please consider giving it a try!
