"'Everything is on fire, but at least this guy is not cold anymore!'; Cool, at least somebody is saying the truth, not everything is black".
There's no middle. There are projections, and there are what we are already seeing.
Of course reality is complex. Of course increasing CO2 levels might have some benefits. But there's no way, all things considered, it's a net benefit overall. Why would you need to point out that look, there are benefits? It doesn't matter. We still need to fix this and for that, we need more concern about climate change, not less (and above all, the relevant people to be concerned).
All this assuming that the planet going greener is a good thing at all. The second sentence of the linked article is literally "Scientists are worried".
