These days, sourcing news items before hitting the share icon is a responsibility we all must bear. That burden of proof should be even higher if you brief the President of the United States.

This week deputy national security adviser K.T. McFarland was scolded by White House Chief of Staff Reince Priebus for slipping into President Donald Trump‘s to be read pile a fake Time magazine cover supposedly from the 1970s warning of the impending ice age, along with a cover from 2008 about climate change. The long-running internet hoax was thankfully revealed as such before the President could talk or tweet about it.

Given the high levels this hoax was taken to, this week’s climate jester is MacFarland, and really, anyone who knowingly distributes fake news. (But we know that’s not you!)
