IMO the worst isn't the AGW alarmist theories and hype of methane escaping from the permafrost. The concern is fuel and gas pipelines and the cities across Siberia that house personnel and families who work in the oil and gas fields. All were built on the permafrost and are now sinking. Causing spills and major damage to the surrounding ecosystems.

As for the methane

“The increase was primarily fueled by human activities—especially agriculture and fossil fuels,” explained Benjamin Poulter, a NASA scientist and coordinator of the wetland methane emissions estimates for the Global Carbon Project. “The specific activities that we linked to the biggest increases were raising livestock, coal mining, waste disposal in landfills, and gas and oil production.”
Across the study years, wetlands contributed 30 percent of global methane emissions, with oil, gas, and coal activities accounting for 20 percent. Agriculture, including enteric fermentation and manure management, made up 24 percent of emissions, and landfills comprised 11 percent. Sixty-four percent of emissions came from tropical regions of South America, Asia, and Africa, with temperate regions accounting for 32 percent and the Arctic contributing 4 percent.

High-latitude ecosystems are particularly vulnerable to climate change. Large amounts of carbon are stored in frozen soils (permafrost) and in forest vegetation in the Arctic. As it thaws, water-logged soil becomes an ideal environment for methane production. “However, we have yet to detect abnormal methane emissions in higher-latitude regions,” said Poulter, “despite thawing permafrost and record-breaking air temperatures year-after-year.”



The video above is a data visualization that highlights several different sources of methane emissions produced around the globe and throughout the year. It was created using output from a modeling system developed and maintained by NASA’s Global Modeling and Assimilation Office. Note that the height of Earth’s atmosphere and topography have been vertically exaggerated approximately 50 times higher than normal in order to show the complexity of the atmospheric flow.
