Putting up solar panels is great, but what is often missing from these optimistic pieces is the fact that globally, fossil fuel usage is still going up. Even in the west: coal, oil and gas plants aren't decommissioned as more solar farms go up (and economically, why would they?). And let's not get into transportation, where I don't see muany realistic plans to replace the current fleet of vehicles by electric ones.
So, all of this to say, I do not believe we'll live in a carbon-free world in a decade. At best, I can imagine something like that in 2060, and even then... My point is that we're already in a +3°C world when the "absolute limit" was set to +2°C 10 years ago. And it's not slowing down. We're currently on the worst trajectory envisioned by previous IPCC reports.
