Here's How to Talk About Uncertainty

A new handbook from the Climate Outreach & Information Network explains how to communicate uncertainty around climate. As the report notes, "too often, climate scientists find themselves apologizing for what they don’t know, rather than confidently communicating what they do know." Here are a few key takeaways.

1) Remind your audience that even if scientists don’t know everything, they know enough to be worried.

2) Explain that scientists agree. In fact, 97 percent of climate scientists believe the climate is changing and humans are the cause (Cook et al., 2016).

3) Talk about risk, not uncertainty. The risk of drought, floods and heat waves is higher as a result of carbon pollution.

4) Tell human stories about real people. Show how climate change is hurting people now, and what it means for humankind in the years to come.
