Between the very cold winter in many places and everyone including Vanity Fair focused on the economic downturn, many in the news media took a vacation from global warming alarmism. But on April 6, NBC brought the hype back with yet another story about the threat of melting ice caps.

Anchor Brian Williams introduced an "Our Planet" segment by reminding viewers that the Obama administration was remaining active on the issue of climate change.

"The Obama administration is calling for greater protection of the earth's polar regions, including limits on tourism," Williams said. "Secretary of State Hillary Clinton made the proposals at a global summit in Washington. Coincidentally, it comes two days after a crucial ice bridge collapsed at the South Pole, effectively changing the map of that part of the world."
