Climate change is at the forefront of our cultural conversation about science, influencing everything from presidential debates to Leonardo DiCaprio's 2016 Oscar acceptance speech. The topic is becoming increasingly socially and scientifically relevant but is no closer to being resolved. Most high school students take a life science course but significantly fewer take earth or environmental science. This leaves life science educators with the critical task of conveying information about climate change despite many having never received any formal education on the topic themselves. In this "Feature," the authors highlight free online resources that will be useful for science educators teaching climate change to high school and undergraduate students.
