We're still only demonstrating ability to react to a sudden media-worthy crisis that is putting people (including decision makers) at a very minor risk of death in the very short term.

For climate change, we need to demonstrate the ability to proactively avoid a creeping catastrophe that will occur in the medium-long term, where the harm may not happen to current decision makers, but will instead happen to other people who don't get a vote in the decision today, and isn't media worthy since nothing is really changing ("outlook remains bleak").

To someone who can understand abstract concepts like "the future," the behavior of world leaders can seem terrifyingly callous, irresponsible, incompetent and maybe even malicious. However when the nasty package shows up on their doorsteps, they can function normally, at least if they're part of a functioning society.
