Climate scientists this week expressed alarm after "unprecedented" data showed the Northern Hemisphere Jet Stream crossing the Equator. In a column on Tuesday, environmental blogger Robert Scribbler noted that the Northern Hemisphere Jet Stream had merged with the Southern Hemisphere Jet Stream. "It's the very picture of weather weirding due to climate change. Something that would absolutely not happen in a normal world," he wrote. "Something, that if it continues, basically threatens seasonal integrity." "Like many extreme events resulting from human-forced climate change — this co-mingling of upper level airs from one Hemisphere with another is pretty fracking strange," Scribbler explained. "Historically, the Tropics — which produce the tallest and thickest air mass in the world — have served as a mostly impenetrable barrier to upper level winds moving from one Hemisphere to another. But as the Poles have warmed due to human-forced climate change, the Hemispherical Jet Streams have
