You know what, maybe I did judge a book by its cover. Let's take a look a the next several sequential usages of "climate", no cherry picking!
> This is something the average climate activist doesn’t seem to understand. Even if we could stop climate change, our civilization would still have the problem of dwindling resources.
> To accomplish that, the damage we’ll do to the environment could potentially outweigh the damage done by climate change.
> If you don’t believe me, I’m going to quote a letter written by experts in Earth science and delivered to the United Kingdom’s Committee on Climate Change a few years ago.
> And unfortunately, climate change is making it harder to grow these trees. Droughts and floods are making them struggle to survive, and tapping too much of the sap (which is used to make rubber) can kill them. Plus, they are very vulnerable to white root disease, and climate change is making leaf blights like that more common.
...and its exactly what you would expect from the title.
>How do I know this? Let’s start with humanity’s biggest problem. No, it’s not climate change. It’s something most people have never even heard of.
