Siberian Crater Mystery Solved

Siberian Crater Mystery Solved

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.

The actions of the U.S. meat industry throughout the pandemic have brought to light the true corruption and waste that are inherent within our food system. Despite a new wave of rising COVID-19 cases, the U.S. Department of Agriculture recently submitted a proposal to further increase "the maximum slaughter line speed by 25 percent," which was already far too fast and highly dangerous. It has been made evident that the industry will exploit its workers and animals all to boost its profit.
