Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

I'll beg to differ. It's actually very "low-hanging", as it could be almost removed very quickly. Yes, that would not be at equal level of satisfaction, but it's possible pretty much instantly.

What you describe are major priorities. They are not, though, low-hanging fruits. Full decarbonisation of electricity production is a massive task, and one that will actually create a lot of emissions, which would thus have to be gained back (as would emissions from peaker plants).
But that'd only be the start, as to de-carbonise other activities, electricity production would have to double.

And of course, there are other GHG than CO2.

The point is not just to "keep the program busy for at least a decade". It's to have started reducing CO2 concentrations before the end of the next one. Not emissions. Concentrations.

I don't see how that would be achieved without making sacrifices in terms of availability of air travel (OK, not total disappearance, but enough that visiting my friends once in a decade would be problematic -yes, we are talking Australia, New Zealand, Laos...) during the transition period.
The alternative is to let some catastrophes happen. I believe it is the more likely scenario. We would have needed to start a massive program earlier.

Earth provides enough to satisfy every man's need, but not every man's greed. Gandhi
