Most people in the UK agree that the UK should pay part of the costs
for poor countries of "climate action".
The problem with this poll is that it poses the questions in the wrong
order. First of all, how much will "climate action" (a vague term)
cost? That depends on another question: what exactly is "climate
action"? Are we talking about sea walls and drains, or are we talking
about decarbonization?
If we get cracking on reducing global heating and other damage to
natural ecosystems, the total price will be less; it may be bearable.
In that case, it will make sense to adjudicate who ought to pay what
share.
If on the contrary the planet roasters continue to delay actions to
reduce the damage, the cost may grow to far more than the whole world
can ever pay. That will mean we have hit total disaster, and there is
no longer a global system in which any adjudication could actually be
carried out, so the question has become purely theoretical.
What about intermediate scenarios? I can imagine that millions of
people in wealthier countries would say, "Yes, I agreed we should pay
part of the costs of helping poor countries cope with global heating,
but there is a limit. We refuse to live in penury!"
To help poor countries is feasible and just only if the rich people in
the wealthy countries bear most of this burden. We non-rich must not
accept this burden for our countries while leaving until later the
question of how much of that burden falls on the rich people.
We know that they will try to dump all of it on the non-rich.
