Palin argued that global warming was not happening, pointing that it was snowing in Alaska in May.

According to the Huffington Post, she wrote in a post on her Facebook page 'global warming my gluteus maximus'.

In her Facebook argument, Palin confuses weather with climate, a mistake frequently made by climate change deniers.

Palin has made this blunder in the past too, suggesting that local atmospheric conditions over short periods of time and small areas have bearing on larger trends averaged over long time periods and greater areas, the report added.
