Russian Scientists: Global Warming Played Major Role in Siberian Craters

Giant methane blow-holes in Siberia have many scientists worried about runaway climate change.

Last night on MSNBC's The Ed Show, Ed Schultz explained that scientists believe the massive craters are caused by thawing permafrost and directly linked to the abnormally hot Yamal summers of 2012 and 2013. As temperatures rose, the permafrost thawed and collapsed, releasing methane that had been trapped in the icy ground.

Joining Schultz last night was Dr. Reese Halter, distinguished conservation biologist and author of nine books, who said, "This is a ticking time bomb. The only thing we can do is reduce the amount of fossil fuels that we are spewing daily, 85 million tons of greenhouse heat-trapping gas, into the atmosphere."

My wife and I built a house two years ago on a few acres of woodland outside of Pittsburgh. The backyard is full of maples, poplars, briars and common spicebush. Two-lined salamanders and grumpy-looking crayfish wade among the rocks in the small stream that runs down the edge of the property. Deer, raccoon and opossum tracks appear regularly in the snow and mud. Sometimes, my trail-cam even catches a pair of gray foxes as they slink through the night.

The U.S. Environmental Protection Agency (EPA) in April 2018 proposed relaxing standards related to how it assesses the effects of exposure to low levels of toxic chemicals on public health.
