They are commenting on the problems with politics in the field of climate science.  But I get it. Its not neutral because it says things you don't agree with. The only "neutral" sources are those that say exactly what you want to hear. I find it amazing that you can so completely lacking in self awareness while hurling accusations at me. I suggest you do some reading:https://en.wikipedia.org/wiki/Psychological_projection

And if you think my having formed an opinion based on my having looked at the evidence available suggests a lack of self awareness, then the best advice  I can suggest is you read and take heed of the link you included.

Why wouldn't you go over the north pole when flying some routes? You realize it is simply a point in the middle of the Earth plate? It also has a giant magnet under the ice.

It depends what pole you are talking about, geographic or magnetic. The former has the good grace to stay where it was put. That god damn latter one keeps moving around. Luckily we can find it with a compass. But who cares, it's a place you'd likely like to put in the rear view mirror.

Actually the former moves around as well. The best known is the axial precession which is about 25,772 years long, but there are also many shorter term wobbles that are just beginning to be understood due to the GRACE satellites (NASA/German Aerospace Center Gravity Recovery and Climate Experiment).

Big difference between the magnetic and geographic poles. Lots of reasons to fly close to the North Pole and none to fly over the South Pole. There is little down there other than the Antarctic. Cape Horn is the same latitude in the southern hemisphere as Glasgow in the north. Ft. Mac is 100 miles farther north than Cape Horn is south.

The true north pole does move somewhat spatially due to the slight wobble in the earth's rotation. But it's location in relation to the rest of the globe stays put. The mag pole does change it's relative location.

Your next lesson will be on plate tectonics.

The plate below the axis can move without changing the actual axis.

If you look to the lower left corner of this (aviation) document you will see the two conjoined arrows that indicate the difference between geographic and magnetic north at this location. It also shows the annual rate of change based on the current activity of the mag pole.

this (aviation) document [YYJ]

I've never flow into there, or been in the terminal, but I have sat at the end of the runway watching the planes come in on a few occasions.

Variation at YVR still 23E? I’m assuming it must be close as the runway #s haven’t changed. Back in the late seventies the numbers at YYZ changed because Mag N had moved enough to warrant it.

That’s what I understood, the axis changes but the location stays the same. Wouldn’t swear to it though.

17 degrees currently. And I do recall flying into YZ when I think it was rwy23 became 24. I had to do a little research after that to see why. Luckily it didn't pose a great threat to a successful landing.

Wow, I am ancient. There used to be a bar in one of the YYZ strip hotels (Ho Jo’s I think) called Runway 23 because it was right on the approach to 23L. Don’t remember what they changed it to. It wasn’t Runway 24.

My understanding is if you were currently sitting directly at the point of axis, that point may move away from you due to the slight wobble in the earths rotation. Or, you could be moved away from it due to plate tectonics. Of course that would  happen constantly at the north pole since you would be sitting on a sheet of ice that is constantly moving. Now another scientific situation that lies ahead is that we will some day have to adjust to a 25 hour day due to the fact the moon is inching away from earth and causing a slight slow down in our rotation. However I wouldn't rush downtown to buy a 25 hour clock. Estimates are it will take ~ 200 million years to acquire thatg extra hour.

We are not even at a 24 hour rotation yet (3 minutes, 55.9 seconds short), the reason we perceive the day as 24 hours is because we are also orbiting the Sun and it takes slightly more than one rotation to get to the Sun to face the same point. If our orbit was in the other direction then it would be the opposite (i.e. Perceived to be shorter)

I believe the Moon acts the same as a figure skater.moving their arms in and out to vary their speed of rotation.
