    There is recent evidence that our magnetic field is changing at an increasing rate. An ancient tree i n Australia has been unearthed.
    "Understanding what happened to the tree during the event could provide an insight into what we should expect the next time it happens. "We will have increased cosmic radiation. It will take out satellites and it might take out other communication infrastructure,"

    On a scale of 1 to 10 of 'things that keep me awake at night', this rates a 0.

    Yeah, I might not lose too much sleep. Does raise a few questions, though.

    "Turney told Newsweek: "The precious thing is this huge, lonely tree grew for some 1700 years..."

    Just exactly how lonely do trees get? Do lonely trees make better tonewood?


    "Magnetic field reversals happen at random intervals, although in the last 20 millions years it appears to have settled into a pattern, happening once every 200,000 to 300,000 years, NASA says."

    All due respect, but 20 million years is a drop in the ocean, because, random.

    This is how science kinda of manipulates the press to further the grant/research thing. Not saying that's bad, because research is good, but how do we tilt the story to cause alarm?

    and of course, the clickbait at the bottom of the page: "Human Barbie takes off makeup, Doctors left speechless".

    Hey, I'm glad it's Friday!

    Being of a practical mind, and maybe a bit of a penny pincher, I could not help wondering how much the research for this valuable piece of information cost, and how will those expenditures be recouped? Lonely tree, hmmmm. Maybe I need to talk to my shrubs more.

    Very cool. I don't read an alarmist tone at all, nor do I see any data being manipulated for grant money. This is not a grant application, it's pop news with attached advertisements so you can read for 'free'. I do see the way certain 'quotables' are picked up by reporters to answer "why is this a story?" Well for the masses, a dead tree is not a story unless one can captivate the audience. The magnetosphere, though it can't be seen or felt, is the reason there is life on earth, but hey, those are just facts, take it or leave it. Apparently it's not real news until disaster appears at the front door.

    Seems like people take for granted the vast knowledge now accessible to everyday people. Dendrochronology and paleoatmospheric core sampling has contributed much to our understanding, yet some folks only see money being thrown at a tree branch or some old ice cubes.

    It's not about 'panic' but it behooves one to pay attention to their surroundings, in all senses, with the best information possible:

    I'm lonely too, would someone please do some research on me? :)

    The guitars made from lonely tonewood are the best guitars tonally for playing the blues.

    I just thought it was very interesting, not alarming.

    True, the quality of your BBQ will go down. Perhaps scientists could use that as a measure.

    Earths magnetic reversal happen over hundreds of thousands of years and an incredibly slow process (kinda boring stuff). Yet the Sun's magnetic reversal is far more interesting; being every 11 years during the solar cycle. (NASA) (Also quanta magazine has interesting notes.)

    "Agathis" tree .... hmmm isn't that guitar wood?

    I was hoping they had sectioned the trunk to show where the reversals happened and how the tree rings responded over the decades before and after. Very thin article. Which in the end the tree survived through.

    This is a lot more worrisome.

    In the Table selection boxes choose:
    Future (within a year)
    Show 100 entries
    Estimated Diameter click on the ^ sort icon

    Top of the list is a 2-4 km in Diameter
    Top four in the next year are above 1 km in Diameter

    Dinosaur killer asteroid was 11-80 km in Diameter (Mexico Impact)
    The Ice Age kill-off of the global large mammals like Woolly Mammoths 12,000 years ago was 1 km in Diameter (Greenland Impact recently found)

    Change the "Nominal Distance" to <= 1 LD (lunar distance) and those charted asteroids are inside the moon's orbit...

    The article doesn't mention how this will affect the polarity of my pickups. Surely, someone must be studying this.
