Who's complaining? Read the article I linked, it's what the quote came from. Informing people about an issue, discussing it's consequences and listing some solutions is hardly complaining.
I'm not sure why you put problem in quotes, it's an issue that has to be resolved which is the definition of a problem. It's not silly to me to talk about an issue.
You think we should do carbon sequestration with the power. That's a great notion. Should we tell the solar plants they need to do that, should the public build them, or should we incentivize companies to do it somehow?

I just can't see how people are this upset about an article explaining how "more than we can handle" means "people might stop making more" and "we need to figure out how to handle it".

I'm not sure what you're talking about with the fish?
