Natural climate change occurs over millennia. Not something humans notice in a lifetime. Btw the dinosaurs were finished off by a meteorite. Not sure whats going on here, I’m not a cimate activist at all. But this is simply conspiracy theory, the wind farm bit, and you, Salty, have indeed failed to grasp the timescales involved. Thousands of years previously to observe change, now a few hundred. There may be natural change too, but dwarfed by man made.
While it is true that a satellite such as the Moon orbits slower the further away it is, I think there must be more to it than that. If an artificial satellite fires a retro-rocket to slow itself without changing its course, it will fall back to Earth. However, this does not mean that the Moon will fall towards us if energy is removed by tidal friction (if this actually occurs), but as for why the difference should happen, it is too near my bedtime for such matters. I saw a video some while back about the problem of black holes colliding, when it was proposed that this should be impossible due to the loss of orbital energy as their orbits shrank, if I understood them.
If you want to discuss climate change, there is a forum for that purpose. Meanwhile, take a look at Climate Change - Franks-Weather - The Weather Window.
PBCox did explain the whole thing at the time, and it did make sense but agree it’s counter intuitive to me too.
You’re saying professor Brian Cox is wrong? That’s a bold statement, given his credentials.
No, I’m saying you misunderstood him.
I find them really confusing as I then need to go and look up the highest spring tide for that location.
The ‘more to it’ is that orbiting slower doesn’t gain orbital altitude. If you launch a satellite, you manage it's orbit speed according to the height you attain. Low earth orbit needs just over 17000 mph. At lunar distance, it’s about 2500mph. If you slow down an orbiting body, it doesn’t just crash down though, or at least, not in one go. Slowing it does indeed result in it ‘falling’ but that will cause it to accelerate. What happens is it's orbit becomes more elliptical, it’s speed becomes more variable. Like a comet orbit. If the elliptical orbit touches any atmosphere, further slowing will occur, and in the case of the moon, there may be trouble ahead. Otherwise, with no further slowing, the elliptical orbit might well continue for some time. If, and it's a stupendously big if, capturing tidal energy slowed the moon down, then yes, it would collide with Earth eventually. But, like the wind thing, it’s a conspiracy theory favoured by the insufficiently educated.
No it’s not, it’s extremely well understood physics. The energy comes from the moon, anything we do to pull energy out of that system has a braking effect. Kids could show you this with magnets.
I’ve got a great idea for a perpetual motion machine.
