Climate scientist Kimberly Nicholas co-led a study that showed the single most effective thing an individual can do to decrease their carbon footprint is have fewer kids. Despite that finding, she still says that people who really want to have kids should go ahead with their plans. She explains how she squares that circle to Vox’s Sigal Samuel, and the two discuss how to think about the decision to have kids or not and how to make meaning in a warming world.     Read more of Sigal’s climate reporting: Having fewer kids will not save the planet Where to donate to improve climate policy It’s not just Big Oil.
