The recent appearance of giant craters in the Siberian permafrost has intrigued observers and alarmed those concerned about global climate change. Some have even claimed that these craters mark a point of no return for the climate.
Thom Hartman interviewed Penn State University professor Dr. Michael Mann, author of The Hockey Stick and the Climate Wars, on the Green Report about the cause and potential climate implications of these craters.
The show revealed that Russian researchers "have linked the Siberian craters to the abnormally hot summers ... of 2012 and 2013 which were warmer than usual by an average of 5 degrees celsius. As temperatures rose, the researchers suggest, permafrost thawed and collapsed, releasing methane that had been trapped in the icy ground."
Mann said that, while the percentage of methane found inside these craters has been as high as 9 percent compared to an atmospheric level of fraction of a fraction of a percent and methane is more closely linked to warming than carbon emissions, it's premature to throw up our hands and give up. And he explains why continuing to focus on reducing carbon emissions is essential.

Ethics investigations have been opened into the conduct of senior Trump appointees at the nation's top environmental agencies.
The two investigations focus on Environmental Protection Agency (EPA) Administrator Andrew Wheeler and six high-ranking officials in the Department of Interior (DOI), The Hill reported Tuesday. Both of them involve the officials' former clients or employers.
"This is demonstrative of the failures at the very top of this administration to set an ethical tone," Campaign Legal Center Ethics Counsel Delaney Marsco told The Washington Post of the DOI investigation. "When people come to work for government, they're supposed to work on behalf of the public. It's a betrayal of the public trust when senior political appointees seem to give privileged access to their former employers or former clients."

We've known for more than 50 years that smoking cigarettes comes with health hazards, but it turns out those discarded butts are harmful for the environment, too. Filtered cigarette butts, although small, contain dozens of chemicals, including arsenic and benzene. These toxins can leach into the ground or water, creating a potentially deadly situation for nearby birds, fish and other wildlife.

Five years ago this week, an emergency manager appointed by then-Michigan Gov. Rick Snyder made the devastating decision to save money by switching Flint's water supply over from Detroit's water system to the Flint River. Seen as a temporary fix, the new water supply was not properly treated. High levels of lead leached from the old pipes, poisoning a generation of Flint's children, and bacteria responsible for an outbreak of Legionnaires' Disease killed more than a dozen residents.
Did you know that more than a third of food is wasted or thrown away every year? And that only 25 percent of it would be enough to feed the 795 million undernourished people in the world? That's why today is Stop Food Waste Day, a chance to reflect on what you can do to waste less of the food you buy.
