This is the first time I've heard about this issue. If this is as severe and terrifying as these comments are making it seem, why has this not been covered more?

What do you think climate scientists have been screaming about for the past several decades?

I heard about that problem ten years ago, without specifically looking for it. It's probably known for decades.
