"Wheel of Fortune" host Pat Sajak tweeted some harsh words about those who are concerned about climate change and its effect on the planet.

"I now believe global warming alarmists are unpatriotic racists knowingly misleading for their own ends. Good night," Sajak wrote Monday.

In an earlier post Sajak, a former TV weatherman, said, "Very hot weather: ‘We're all going to die!' Very cold weather: ‘There's a difference between climate & weather, moron!'" He then added, Help...climate changing...must send money to lots of places...a lot of money...hurry...time is short...not kidding..."

Sajak then took a shot at Al Gore and the 2006 documentary "An Inconvenient Truth", which helped raise awareness of the dangers of climate change by tweeting, "My interest in Al Gore's pronouncements could fit into a gnat's navel & still leave room for a Liberal's sense of humor."

The tweets obviously raised some controversy, which apparently was what Sajak meant to do, judging from his latest tweet: "Sometimes it's fun to poke a stick in a hornets' nest just to hear the buzzing."
