Shrinking glaciers, Arctic temperatures and a mix of messy energy politics await President Barack Obama on his historic trip to Alaska. Even before he departed, Obama was making waves with a decision to rename Alaska's famed Mount McKinley despite a backlash from Ohio politicians.
Obama flies to Anchorage on Monday morning for a three-day tour of the nation's largest state, closely choreographed to call attention to the ways Obama says climate change is already damaging Alaska's stunning scenery. By showcasing thawing permafrost, melting sea ice and eroding shorelines, Obama hopes to raise the sense of urgency to deal quickly to slow climate change in the U.S. and overseas.
My Way News - Alaska-bound, Obama makes waves by renaming Mount McKinley
BUT WAIT!!!!
While Arctic sea ice continues to decline,
Antarctic levels are confounding the world’s most trusted climate models with record highs for the third year running.

Antarctic ice floes extended further than ever recorded this southern winter, confounding the world’s most-trusted climate models.
“It’s not expected,” says Professor John Turner, a climate expert at the British Antarctic Survey. “The world’s best 50 models were run and 95% of them have Antarctic sea ice decreasing over the past 30 years.”
The winter ice around the southern continent has been growing relatively constantly since records began in 1979. The US National Snow and Ice Data Centre (NSIDC), which monitors sea ice using satellite data, said this week that the year’s maximum was 1.54m sq km (595,000 sq miles) above the 1981-2010 average. The past three winters have all produced record levels of ice.
Why is Antarctic sea ice at record levels despite global warming?
