With respect, I think you're projecting a discussion with a different person onto this article.
You're right, the climate is going to get worse before it gets better. You're right, the impacts of climate change will disproportionately affect poor and underdeveloped areas. We can't make that go away with positive thinking, and it's not enough for humans as a species to survive, we need to focus on reducing suffering while we're turning the ship.
What I took away from this article is that the market forces for cheap renewable power and the means to store it are now stronger than the forces for CO2 emitting power. And those forces are moving faster than predicted. That's good, and it's ok to talk about something good when it's true!
People who have been paying attention and care about others have good reason to be wary about the narrative "oh, everything is going to be fine" because that's what industry and politicians have been saying for a long time instead of taking needed action.
We're at a point where most people recognize climate change is real, and they can see it's effects. We're also at a point where many people don't have hope for the situation. It's dangerous to tell people "shit's fucked and there's nothing you can do about it" because they might believe you and do nothing.
