What should we do about it?
Unfortunately, they have no realistic solutions and continue to scream at others and cause wanton chaos and panic. Year after year, they are just as bad as the ones in power that are not doing anything.
Both screaming, yelling, panicking and being idle are not solutions.
But at least you can't scream or say that technologists in companies developing EVs or net-zero solutions in other vehicles are not doing anything. That is what we need more of, and that is far significantly better than the talking and screaming that is going on at these conferences; even when they all flew in private jets to have these talks about 'climate change' but they are making the process quicker instead.
Perhaps having a Zoom / Skype conference call, would be much greener than representatives from 200+ countries flying in and out of the conference.
You can have multiple threads of conversation at the same time; it relies on arguments, not charisma; it easier to search, index and reference; it is faster to read than to listen; it is 'greener' in every way.
