As the death toll continues to rise and search and rescue teams continue to look for victims, the devastating flood in Kerr County, Texas show not only the vital role of weather forecasters, but also climate researchers who help make more accurate predictive models, and the coordinators and other administrators with the experience to make sure the right people are working with the right information. Eric Holthaus, meteorologist and climate journalist, talks with Rachel Maddow about the challenges weather officials face with climate change and staffing cuts under the Trump administration.

Rachel Maddow takes a look at the sudden flood of artificial intelligence-generated fake stories on social media, using false stories with her at the center as examples. These false stories have her doing everything from rescuing Texas flood victims, to having a baby, to starting her own news network, none of which are true. The lesson is that now, more than ever, it is important to check the source of anything you see or read.
