This week’s climate jester hat goes to Wisconsin Sen. Ron Johnson, who in a question and answer period with high schoolers in his state, said he doesn’t see cause for alarm over climate change.

“I’m skeptical that we can do much about it,” he said. He argued that billions of dollars in funding wouldn’t have kept the Ice Age at bay.

Last year, Johnson compared those who advocate for climate solutions to infamous dictators such as Fidel Castro, Josef Stalin, and “the nutcases in Korea.”
