While many of us are deeply concerned about North Korea, predictably, the ultra-conspiracy wing of things tells us that it is all a conspiracy and that there is nothing to worry about. Thank God for that! This must all be nonsense:

     But, wait! Now there is talk that North Korean underground nuclear tests, may have awoken a super-volcano: http://www.zerohedge.com/news/2017-09-16/north-koreas-nuclear-tests-could-trigger-supervolcano-eruption:

“After North Korea’s latest nuclear test, scientists are worried that more underground explosions in the isolated country’s rocky north could set the stage for a deadly volcanic eruption not unlike the one that NASA fears could be brewing in the Yellowstone caldera.
Following the North’s sixth nuclear test Chinese authorities have stepped up radiation monitoring and even closed part of their border with North Korea as fallout fears have intensified.
And now, as Newsweek reports, China has limited access to a nature reserve on its border with North Korea after a mysterious series of seismic shakes at the rogue nation’s nuclear test site were detected less than 10 minutes after it conducted its latest test, which also triggered a sizable tremor. The severity of the tremors prompted Beijing to close the site over fears that underground detonations by the North Koreans at a facility near Punggye-ri could lead to rockslides, or worse, trigger an eruption of the active “super volcano” Mount Paektu, according to Disclose.tv.
According to Disclose.tv, the magma and sulfur booms during a supervolcano eruption could kill millions of people in the surrounding area, and potentially endangering all of humanity.
The volcano, which is sacred to North Korea, is located right on its border with China. China’s closure is in effect for a 70-mile-radius around the detonation site. A blast from a super volcano could be catastrophic, with ash traveling thousands of miles, potentially causing hundreds of thousands of deaths
“For the safety and convenience of travelers, we have temporarily closed the southern tourist zone of Changbai Mountain,” read the message from Chinese authorities, translated by UPI. “Officials are thoroughly investigating the safety of the tourist area.” The area will remain closed to the public until “the potential risks disappear,” it said.
But besides radioactive risks, scientists are worried that North Korea’s nuclear tests could disturb mountains in the Changbai range, along with the still-active Mt. Paektu, triggering the first eruption since 1903.”

     Apparently if the super-volcano erupts, it will dwarf previous recorded eruptions, plunging the world into a volcanic winter, leading to mass starvation as the skies are filled with volcanic gunk.
     See, I told you that it was a waste of a good worry fretting about global warming. Now we can worry about something really deadly.
