National Geographic has a great story and video about the shrinking ice in the Arctic.  Many want to deny the warming planet, but the evidence is obvious when you look at the extent of ice in the Arctic Ocean.

Unveiling his most aggressive plan yet to combat climate change, President Obama on Monday referenced recent dramatic changes that National Geographic made to its atlas because of melting sea ice.

“Shrinking ice caps forced National Geographic to make the biggest change in its atlas since the Soviet Union broke apart,” Obama said during a speech at the White House.

He’s right. The shrinking of the Arctic ice sheet in the 10th edition of the National Geographic Atlas of the World is one of the most striking changes in the publication’s history.

After the publication of the atlas in September 2014, the ice has melted even further, notes National Geographic Geographer Juan José Valdés.

“The end of Arctic summer is still several weeks away, and it’s still too early to say if another record will be broken. But one need only look at the maps derived from satellite imagery to see the impact of global warming,” he says.

Obama on Monday released the final rule of his so-called Clean Power Plan, which aims to address climate change by reducing heat-trapping carbon dioxide emissions from power plants.
