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.

A judge in New York's Supreme Court sided with Exxon in a case that accused the fossil fuel giant of lying to investors about the true cost of the climate crisis. The judge did not absolve Exxon from its contribution to the climate crisis, but insisted that New York State failed to prove that the company intentionally defrauded investors, as NPR reported.

You may have heard that giving a pet for Christmas is just a bad idea. Although many people believe this myth, according to the ASPCA, 86 percent of adopted pets given as gifts stay in their new homes. These success rates are actually slightly higher than average adoption/rehoming rates. So, if done well, giving an adopted pet as a Christmas gift can work out.
