“Some call it a doorway to hell. Or a portal to the underworld. Scientists call it a crater…The [0.6 mile long and 282 foot deep] Batagiaka crater in eastern Siberia, already the largest of its kind, has been growing…[It] is caused by melting permafrost…Melting began in the 1960s, spurred by rapid deforestation…[The hole’s growth] has accelerated further in recent years as the planet has warmed steadily, spurred by rising greenhouse gases…[I]t may also be a cause of warming temperatures…[because] as much as 50 percent of the Earth's methane gas may be stored in Arctic and Northern Hemisphere permafrost (methane is a greenhouse gas more powerful than carbon dioxide)…[Greenhouse gases released from Siberian permafrost in the last ice age have been linked by research to a significant spike in temperatures which researchers say] could happen again…[Dozens of other permafrost-induced craters have been identified in Siberia]…” click here for more
