@gretathunberg "incredibly disappointing" seems exaggerated; disagreement with or qualifications about the things Attenborough was saying are sensible.
Suggesting that he is ignoring historic responsibilities and overall inequities in the world is intellectually unfair. I'm certain he's well-aware of and shares concerns about these things. He's not some oblivious person who doesn't get it.
Net-zero 2050 might be too-little-too-late, but it's doubtful we'll even get that much progress.
