This week, President Obama announced his Clean Power Plan, a multifaceted program to cut carbon emissions by 32 percent of their 2005 levels, by the year 2030. As the president himself said in a speech announcing the plan, "There is such a thing as being too late when it comes to climate change." But is this plan itself too little, too late? David Biello of Scientific American helps us answer that question.
Then, we check in on the global hotspot for climate change: the Arctic. Brendan Kelly of the Monterey Bay Aquarium talks about the weird hybrid species, such as "pizzly bears" (polar/grizzly hybrids), that are appearing on land and in the Arctic Ocean. Reporter Ari Daniel and physical oceanographer Fiamma Straneo check in from a boat in Sermilik Fjord, in Greenland, to talk about glacier calving there. And ornithologist George Divoky calls in from Cooper Island, a sand and gravel bar on the north coast of Alaska, where he has studied black guillemot birds for 41 years.
