No. Big oil may be as greedy as they want, they won't benefit in any way without customers who buy their stuff. Customers who just ignore the immorality of it all in order to warm their houses, drive their cars, and power their computers.
Ehm..., you don't happen to be one of these customers, do you?

So, what do you need a scientist for?

People tend to think scientists know everything. In fact, science is far from complete. I don't think IPCC can predict the average temperature in 2100 yet. However, the underlying science will keep moving forward and provide humanity with better weather forecasts, earlier warnings for floods, hurricanes and earth quakes, and other useful knowledge. Eventually, science may get to the point where they can explain the chaos model that makes up our climate. Just don't hold your breath.

Due to warming i magine places currently too cold will become hot enough to live.

Indeed, some Russians were excited about the prospect of Vladivostok becoming like the "Riviera of the Arctic".

The trouble is, extra rapid warming at the poles has recently exceeded 20°C, more than humans can adapt to.
Not to mention other species.

And places currently hot will become too hot (eg no rain).
Result, people will have to adapt, and relocate more away from the hot-equator, and more towards the cooled poles.

You make it sound simple, a few billion people having to move - mostly those with the least resources to do so.

But i suspect the habitable reagons to be the same, what is lost around the equator is gained around the poles. No ?

Swings and roundabouts, eh?

Again, what about the many thousands of species that can't just "up and move"?

Especially when we've destroyed most of their natural habitats already.

Half a year of dangerous heat beckons for parts of Australia in 1.8-degree warmer world

Good luck with "brightsiding".

I think there are two bugs in this (and they are related).
One: pushing the blame around leads to no useful outcome whatsoever.
And two: if someone earns a fortune, and then spends it in one day, that is in no way "immoral". It is plain stupid.

It seems indeed that science has taken the role of a priesthood, and what should be intelligent decisions are now considered something like "moral" issues. I think that is wrong. I think you should try to consider the entire civilisation as one big single organism, and only ask what is done in total (no matter wo does what individually), and then ask: is this an intelligent decision what we are doing?

So I thought, right from the beginning, that it is a bad idea to burn the oil, because we will need that oil to drive rockets to go up into space - and we may want to do this for another thousand or more years until we find a better means. That's the point.

Then, concerning the items you mention: forcing everybody to have their own car, maintain that car, keep it running, find places to park it, get stuck in traffic jams, get it occasionally damaged, etc.etc. is just a very big hassle. It is not an intelligent decision. It would be much more pleasurable to have a public transport system that actually works and that you can use for 99% of your moves without bothering about anything - and that would be easily possible if all the effort would go into that.
It's similar with houses: if all effort would go into making them self-sustained, many things would be possible.

And then we get back: the reason why we do not create intelligent decisions is that the effort is not driven by achieving them. The effort is instead driven by people wanting to make money.

And that is the actual bug. And you do not only hit it here. You also hit it when you are designing a new system, and some manager tells you about "time to market". And at many other places.

The climate is my least concern.

If you prefer being anxious and moody in 2022 because of what might eventually happen in 2050, well, have fun. Your article about a 1.8-degree warmer world is based on yet another future projection, and so far these projections haven't been very accurate. But should it come true this time, you can solve most of the problems mentioned in that article by installing a small airconditioner in 2049.
 
When you listen to Jean-Marc jancovici in a conference (french) he try to make a joke related to what he say about at every minute and generally, the audience do not laugh but he try. He speak fast too what make me hard to follow him. Well, it seem's that he is better as a scientific than as a humorist. He say a lot of words in one minute. He is a brilliant man this is sure.
