Pastor Robert Jeffress, who serves on President Trump's Evangelical Advisory Board and the White House Faith Initiative, had words for young climate activist Greta Thunberg.

Jeffress appeared on Fox Radio's Todd Starnes Show on September 23 to discuss the United Nations climate summit, which President Trump notably attended for just 14 minutes before heading to give an address on religious freedom.

On the program, Jeffress referred to climate change as an "imaginary crisis," telling listeners that Trump was right to skip the summit. He then pivoted to discussing Swedish climate activist Greta Thunberg, who has become the face of the global climate justice movement.

"Somebody needs to read poor Greta Genesis, Chapter 9," Jeffress said, "and tell her the next time she worries about global warming, just look at a rainbow. That's God's promise that the polar ice caps aren't going to melt and flood the world again."

There is no scientific evidence connecting rainbows with the preservation of the polar ice caps.

Starnes agreed with Jeffress, commenting, "This whole global warming, tree-hugging fiasco—again, there is nothing to it. As you point out, they might as well hold a commission on the Tooth Fairy or Bigfoot, Sasquatch."
