Not all journalism or scientific reporting is about presenting solutions, and pointing out the problems (especially of this severity, if the article is to be believed) is an important step. Furthermore, as the article says, I don't think anyone knows the solution. Even if we drastically reduce carbon emissions, it probably won't help.

I often find an attitude of dismissal and disdain towards environmental reporting like this on Hacker News. I think it stems from how we're so used to the optimism and can-do attitude of Silicon Valley that it's hard to digest how we may have created a problem we can't solve. It feels better to think "oh, they're just not being innovative enough in their solutions" and present oneself as above the fray.

But the stark reality, if the science is to be believed, is that we're on the path towards major environmental changes in the foreseeable future, and as of right now, we don't have a solution.
