Perhaps decoupled isn't the right word. I also used 'different'.

Given the pushback, I'll not watch it again, but there was discussion of the Coriollis Effect. The trade winds create three zones. Does that work?

It's an artifact of latitudinal velocity around Earth's spin axis.
At the Equator, the ground underfoot is moving with a velocity of 1,032-mph at that average mean radius from Earth's center.
It's zero at the poles.
The further you move north, or south of the Equator, the 'slower' the velocity.
It's what explains the direction a whirlpool forming in a sink or bathtub exhibits. They're 'opposite' depending on which 'hemisphere' you're in.
( computer-generated military sniper firing solutions for their Barret 0.50 long guns must incorporate the 'Coriolis Effect' in order to compensate for their target, that may be a mile away in latitude )
Fluids ( air and water ) on Earth's surface ARE affected by the effect, but there are a lot of other dynamics also influencing 'local' phenomena. This is where Lindzen went off the rails.
As he's a 'meteorologist ( a very good one on all accounts ), and not a 'climatologist', he would not have the specialized knowledge of those who pushed back against his 'childlike' global warming hypothesis ( he just didn't know what he didn't know ).

Of course I know what the Coriolis Effect is (even if I can't spell it corectly). I was wondering how Hadley Cells differentiate the regions rather than diffusing them.

Hadley cell
The Hadley cell, also known as the Hadley circulation, is a global-scale tropical atmospheric circulation that features air rising near the equator, flowing poleward near the tropopause at a height of 12–15 km above the Earth's surface, cooling and descending in the subtropics at around 25 degrees latitude, and then returning equatorward near the surface.

...there are a lot of other dynamics also influencing 'local' phenomena.

This is the part I was concerned with.

What part of 'expert' are people not getting?

This is the part I was concerned with.

The moist equatorial heat creates the convective available potential energy ( CAPE ) which causes the vertical movement up to the 'top' of the 'climate', which 'decompresses' it as it moves higher into more, less-dense, rarified air, where it loses heat of compression ( exactly as in a refrigeration cycle ), then falls northwards, where it's cooler/denser mass causes it to descend, traveling back to its origin.
There's something specific about the 'conditions' around 25-degrees, N-S latitudes that constrain the circulation ( El Nino, La Nina, Rossby waves, sea surface temperatures, ocean currents, island archipelagos, ocean gyres, wind, whitecaps, marine cloud layer, stratospheric clouds, atmospheric aerosols, Saharan dust, contrails, coldwater upwellings, submarine thermohaline cycle, seasonal land-based vegetative cover dynamics, diurnal effects, seasonal solar insolation variability, ocean mid-depth dynamics, sea floor dynamics, sea floor topography ( volcanic sea mounts, rift valleys, canyons, tectonic spreading, etc. ), etc..

That's the only part that advances the conversation. First paragraph is a redefinition of Coriolis Effect, the rest is word salad. I did have to look up Rossby waves. So there is that.

The Hadley Circulation ( Intertropical Convergence Zone ) cloud bank initiates wherever latitude is 'directly below ' the sunlight.
The heat gives it the lift, just as with a hot air balloon, taking extreme rain/ monsoonal payloads with it, like the Walker Circulation of an El Nino Southern Oscillation carries moisture E-W.
The air drops moisture as it rises to as high as 8-miles, where it's 68-degrees below zero.
Now cold, dense, and 'desiccated', as far as 25-degrees N or S, it falls to earth as 'aridity' at midlatitudes.
They produce tremendous rain, plus 'deserts.' The southern region presently mined for Lithium, and the Bonneville Salt Flats/ Great South Lake, are created by the ITCZ.
The Coriolis pseudo-force peters out against the 'weight' of the air.
The ITCZ also moves with the ice ages, following the 22,000-year precession of the equinox Milankovitch cycle.

The 'word soup' contains some of the climate components that Richard Lindzen didn't know anything about, causing his fall from grace.

So it's humidity, not temperature that insulates* the poles from the tropics?

*Choose any synonym you desire.

Actually, they're fully-connected by winds and ocean currents:
1) Both poles are warming at a faster rate than anywhere else on the planet.
2) Above the North Pole, the warming has altered the behavior of polar jet.
* The polar jet influences the Jet Stream, causing it to 'meander.'
* The Arctic air is so dense that it 'pours' down from the north, creating a meridional oscillation in the Jet Stream, which can sink below the Equator, literally bifurcating North America for extended periods, with the frigid air flowing south across the Gulf of Mexico, coming ashore in Mexico, an traveling beyond Central America and into northern South America, taking out the annual harvest for many crops ( this is where George Soros has made fortunes in the futures market, buying coffee and bananas before they're destroyed in a hard freeze, sending world prices through the ceiling ).
3) In Antarctica, the sea ice and glacier melting is causing freshwater intrusion into the ocean, which effects the thermohaline cycle which is responsible for heat transport of the Atlantic Meridional Overturning Current ( AMOC ), commonly referred to as the 'Gulf Stream', responsible for supplying tropical heat to N. Europe.
* It also affects the El Nino Southern Oscillation ( ENSO ), El Nino, and La Nina.
* The entire marine food chain for the world is affected by the loss of algae that lives under the sea ice, which we're losing at an exponential rate, at both poles. Without sea ice there's no krill, fish, marine mammals, sea birds, etc..
* A few months ago, Scientists reported that the AMOC has already slowed by 33%.
* A hurricane actually formed off the Eastern Coast of South America a few years ago for the first time ever in recorded history ( 1850 ).

Everything is connected. It's why they call it 'climate', instead of 'weather.'

Connected yet differentiated somehow. The poles used to be tropical, something changed.
