Climate Change Is Altering Global Air Currents (independent.co.uk)

An anonymous reader quotes a report from The Independent: One of the scientists who demonstrated conclusively that global warming was an unnatural event with the famous "hockey stick" graph is now warning that giant jetstreams which circle the planet are being altered by climate change. Jetstreams are influenced by the difference in temperatures between the Arctic and the equator. But the Arctic has been warming much faster than tropical climates -- the island of Svalbard, for example was 6.5 degrees celsius warmer last year compared to the average between 1961 and 1990. The land has also been warming faster than the sea. Both of those factors were changing the flow of these major air currents to create "extreme meanders" which were helping to cause "extreme weather events", Professor Michael Mann said. In a paper in the journal Scientific Reports, Professor Mann and other researchers wrote that evidence of the effect of climate change on the jetstreams had "only recently emerged from the background noise of natural variability." They said that projections of the effect on the jetstreams in "state-of-the-art" climate models were "mirrored" in "multiple" actual temperature measurements. The jetstream normally flows reasonably consistently around the planet, but can develop loops extending north and south. The researchers, who studied temperature records going back to 1870 as well as satellite data, said these loops could grow "very large" or even "grind to a halt" rather than moving from west to east. The effect has been most pronounced during the past 40 years, they found.

    Your house is on fire. Do you:

    A. Call the fire department?
    B. Accuse the neighbor of telling you your house is on fire that "Fire is just somebody's religion!"
    C. Convene a study to determine if the house really is on fire, and if so, if it was due to spontaneous combustion or if there's a arsonist about?
    D. "Blame Liberals!"
    E. Post to Facebook or instagram?

    F. Call the police to report a drunk/delusional hippie running around the neighbourhood who thinks the houses are on fire?

    Uhh, yeah lots of climatologists driving around in Ferraris... Those guys are way too smart to use their brains in the financial or military sectors. The real money is in siphoning pennies from government grants. Good thing Trump sees through the lies.

    So you posted a quote from a website claiming that the CIA has engaged in a time travelling conspiracy involving invisible agents, travelling through time, and when you saw this article, you thought to yourself "the problem with these [ consensus view ] people is that they aren't skeptical enough"

    Sounds legit.
