> You cannot address climate change without drastic long term reduction in human activity/population.

Of course you can. You must change activities to be carbon neutral, but you can maintain the same level of comfort you have today. More than "can maintain", you "must".

If you rely on sacrifice from the whole planetary population in order to tackle climate change, we are doomed. It will never happen, as it goes against the competitive nature of humans.

The correct path is forward: innovate, so that carbon neutral forms of energy and materials are better than carbon-emitting versions. Energy is an almost solved problem, using this vector. Let's attack materials now.






Carbon neutrality is a necessity, as is population reduction. I am not advocating for one over the other. Either alone will not work, not short term certainly not long term.

With atmospheric carbon & population, increasing each of these numbers beyond a certain point (where sustainable thriving is naturally possible) can be seen to be detrimental to all.

As excesses become realized, increasingly, a fundamental relationship between these figures can become measurable.

That exact relationship, the proven algorithm, may not realistically be very well agreed upon in detail, but as these factors rise rapidly above baseline levels that function should more accurately be discerned above the background as time goes on.

Maybe before this happens, sustainability would be better achieved by actions resulting in trends which reduce these two figures low enough in combination where no relationship could then be considered realistic.

So carbon neutrality might not be enough without taking too much from population.
