No one is working on carbon-free renewable energy? Solar power hasn't doubled in efficiency since development began? No one is building wind farms? ICE vehicle fuel efficiency has not been massively increased? No one is making electric vehicles? Supply chains are not getting more efficient? There are no waste reduction strategies being implemented anywhere? There are no efforts to reduce methane emissions?
> We see that while emissions from fossil fuels have increased, emissions from land use change have declined slightly in recent years. Overall, this means total emissions have roughly stabilised over the past decade.
There is some hope that fossil fuel emissions are peaking right around now. See the recent Ember info:

This is not a fatalistic "oh, let's not even try then" statement. It's just facts. Yes, we should try. No, we won't succeed if it's just the US reducing emissions.
So yes, more than nothing has been done to reduce emissions, but you need to look at the right numbers and graphs.
Because no one has suggested using DAC to offset fossil fuel use without reducing fossil fuel use, this is a straw man. DAC may very well be a valid strategy when used in conjunction with the reduction of fossil fuels to better reduce the amount of atmospheric carbon in a given time frame.
