the messaging has been consistently toned down in the hopes people would listen.
My guess is its even more than this: deadlines were extended to not let people fall into inaction. The tipping point always close enough so that its dangerous, but still far away enough so that there is still hope. It is a ploy analogous to the fascist “the enemy is strong enough to be dangerous and weak enough to be thoroughly defeated.”
This scene is far more realistic, I think. But as you can tell, it doesn’t play very well with either the audience or the media.
