That's like being in a car driving towards a wall and saying "see, everything is fine".

The moment climate change affects you personally will be already too late to do anything about it.

Right. But what if you've been told that wall is in ten feet, but you go eleven feet and hit nothing. Then you're told, no just three more feet and you'll hit the wall and you go four and hit nothing.

Then your told, well it's less of a wall and more of a curb and it's in five feet. You go ten feet and still hit nothing.

I guess some people will always be Charle Brown.

When the wall was ten feet away, the wall was "nothing changes", ca 0° warming. Then the wall was 1° warming, then 1.5°, ... We're still accelerating towards 3-5° warming. Coral reefs for example are already doomed, there is nothing we can do to save them. A degree or two more and highly populated areas will become either too hot to live or too dry for agriculture. Then the wars for water and land start.

Coral reefs are fine. In fact, the great barrier reef has made a significant comeback.

And yes, cities get hotter and dryer as they make ever more blacktop and dump all their rain water into the ocean.

No, coral reefs are not fine. Rising water temperature will kill coral over the next decades. We already emitted enough CO2 to raise temperatures beyond what coral can tolerate. The current state of the reef has nothing to do with it.
