I hear ya. I mean when that’s all a person does… yep.Some things should not be diminished! Sometimes crap talk needs to be removed!
I think that most of us are very in support of how this forum is moderated, and we thank all of you for how you doing. frustations come out in posts sometimes and we need to be reminded to "keep our toys in the pram"I fully support posts being deleted if @havasu or @Patchouli find it not fitting into this forum.
I personally think Ben at suspicious observers has a far better take on what is / has actually happened. And look at a compass the magnetic poles are moving and that move is accelerating, so maybe out actual rotational poles noon is 1 3/4 hours late here on the longest dayBack to the topic at hand...
What If Earth's Magnetic Poles Flip?
NASA and other sources tend to minimize the probability of much biological effect when the Earth's magnetic field reverses, but
a study of the reversal that occurred during the last ice age shows that not to be the case.
Around 41,500 years ago, Earth's magnetic field experienced a complete and rapid reversal of the geomagnetic field called the Laschamps excursion, named after lava flows in France, that revealed geomagnetic anomalies. During this event, the magnetic field rapidly weakened, and the poles flipped, only to reverse again 440 years later. The actual polarity changes lasted only 250 years. In terms of geological time scales, that is very fast. During this period, the field was even weaker, with only 5% of today's field strength. As a consequence, Earth nearly completely lost its protection shield against hard cosmic rays, leading to a significantly increased radiation exposure." It is possible this event may have contributed to the extinction of the Neanderthals.
If a similar reversal occurred now, our technology definitely would be in danger. Even now, solar storms can damage satellites, cause power outages and interrupt radio communications. These kinds of negative influences clearly will increase if the magnetic field and thus its shielding function became significantly weaker, e.g. during a reversal, and it will be important to find mitigation strategies/replacement technologies.
Scenario: What would happen if all satellites stopped working?
One additional worry is that a weakening and eventual reversal in the field would disorient all those species that rely on geomagnetism for navigation, including bees, salmon, turtles, whales, bacteria and pigeons. There is no scientific consensus on how those creatures would cope.
Now if the earth's magnetic field just turned off, we're screwed.
Without the magnetic field, life on Earth as we know it would not be possible as it shields us all from the constant bombardment by charged particles emitted from the sun — the solar wind. To learn what happens to a planet when it loses its magnetic field, you only need to look at Mars.
Earth's magnetic field is overdue a flip. Should we be worried?
From time to time, the Earth's magnetic poles flip, leaving us without a protective magnetic field for up to centuries at a time. Geologically, we're overdue, but Space.com thinks any magnetic-field flip would still be thousands of years away...
So, no worries! They know for sure, right?!
Baby strollerA wild, and hopefully short tangent here: What does "pram" mean in this context? I am not familiar with this usage. The only thing I've ever called a "pram" was the rolling/collapsible patient stretchers that we used when I worked on the ambulance.

After reading this I am not going to use anything metal to keep my wine in, as if it flips & my wine gets spilt , the wife will say I am drunk againBack to the topic at hand...
