I agree. But this is the ruling class we have. They thought it was a good idea to occupy Afghanistan for 20 years, and then botched the exit to top it off. Think they'll handle climate change more competently? That wouldn't follow the pattern we've seen for decades.
I certainly think it's likely they'll poorly handle climate change; that's already happened for decades.
Your assertion that they'll try handling it with lockdowns is what I'm contesting, and recent history sides with me, IMO. Said ruling class in most countries couldn't even politically sustain lockdowns for a global pandemic, let alone on a longer, more widespread term for a more abstract threat.
