>The data shows that between renewables, storage, transmission, heat pumps, and electrifying mobility, climate change can be solved.

Gonna need a link to one of those threads full of citations on this claim, because this is not at all my understanding. Even if we had a magic wand that would reduce anthropogenic CO2 (and other greenhouse gas) emissions to zero overnight, we're already far above historic atmospheric CO2 concentrations and will be paying the price.

Edit: since I'm asking for citations, here's mine[1] showing that according to climate models zero CO2 emissions from 2020 onward would have little effect on the global mean temperature through 2100.

It just depends on your definition of "solved". If solved means "all consequences of anthropogenic climate change avoided" then it's obviously too late, there's no solution other than time travel. If solved means "humanity survives as a species" then we're in pretty good shape no matter what we do. For most people I think solved means "we avoid the worst effects", which of course leads to another question about definitions.

Many people look at the graph in your citation and see it as a picture of success, because the baseline in their mind is RCP8.5. Note that the graph makes a comparison to RCP2.6, which is not a "do nothing" scenario, it's a pretty optimistic and aspirational future.
