UN warning

This is about being warned, not un-warned.
The UN has released today a report (how many more needed?) intended as “the final wake-up call to the international community” about the danger humanity is facing. Interesting choice of words - that they labeled it as "final". Climate change, animal extinction and unsustainable population growth are a few of the challenges mentioned.

The NY article announcing it also refers back to a two decades old admonition by the former Norwegian prime minister, Gro Harlem Brundtland, who warned that the survival of humanity was at stake from unsustainable development.

There many different reports and studies over these last few decades - and we have heard "point of no return" often enough that it's a good time to wonder whether we have not passed it already...
For hope's sake I would like to think we have not, but everything I learn of begs to differ.
