The huge expense in trying to combat Global Warmng- through taxes on Carbon, Net Zero- thus helping to stop the higher-latitude Westerlies "Getting out of hand" and causing irreparable coastal erosion in Britain and other parts of northern Europe- is likely to be in vain if we cannot get China and india to curb their CO2 emissions. But at a fraction of the cost, Britain and other countries working together might find another means of taming (and perhaps even reversing) Global Warming by implementing geo-engineering measures that weaken the Westerlies, reduce the number and intensity of strong "warm-front conveyers" associated with depressions that push a little too much heat and wind into high latitudes! If we can reduce the number and intensity of depressions and strong south-west (and southerly) winds moving into the Arctic basin you help preserve the ice there (it may hopefully recover) and that ice then reflects heat from the Sun as it persists through the summer- keeping the Earth cooler.
Some measures to do this include the following:
1) Building a 4,000 metre-high wall (500 metres thick); running north to south from northern Quebec to Atlanta (it can be built just off-shore to avoid it going over valuable farmland and communities). This would be a huge undertaking costing $$100 billions but it would be cheaper than all the huge efforts to combat Global Warming running into $$ Trillions. A 4 km-high wall would be effective at intercepting the Westerlies where they are stronger- the force of the wind against this high wall would be a very effective sink for Westerly AAM- leading to weaker Westerlies downstream. The high wall would also create an upper trough (with depressions and associated Westerlies blowing further south) downstream, bringing rain to the parched Mediterranean and Israel whilst relieving Britain of damaging storms and coastal erosion (and brining about colder, drier winters in Britain, too). The Arctic would get a chance to cool, as would Siberia. That will preserve reflective ice-cover and prevent the Siberian permafrost thawing (and all that entails).
2) A cheaper, more practically feasible option (one that will require International Agreement) is to cover 2 million square miles of the Equatorial Atlantic and Pacific with floating mirrors- perhaps attached to the sea-bed by long chains so that they can't drift over fishing lanes, shipping areas or troucle coastal island communities. The mirrors would reflect away the Sun's heat (helping to keep the Earth cool) and the cooling of Equatorial waters would help weaken the zone of hot-rising air in the deep tropics. This would, in turn, weaken the converging North East and South East Trade Winds, reduce the addition of Westerly AAM to the global circulation and, thus, weaken the Westerly AAM available to furnish depressions and Westerlies in higher latitudes. Weaker Westerlies and depressions in the North means less "warm front conveyer belts", less Winter storminess and the Arctic being allowed to cool. That in turn means more reflective ice there (and also around Antarctica), which could be enormously effective at countering the greenhouse effects of rising CO2 levels. The Med and Israel will get much-needed rain, Britain and northern Europe will benefit from hard winter frosts to kill the bugs and from less coastal erosion. There will also be more decent summers in northern Europe.
However, as far as Climate Change is going, the Clock is Ticking and there is perhaps just forty years to prevent serious Global Warming and all that entails! At the moment a Quiet Sun is helping, by counterring the CO2 warming effect, in forty years time the strong Solar Sunspot Cycles will be back and the Sun will amplify Global Warming. It does not look like we can rely on China.
