The second paragraph of that page says "Climate scientists have identified over a dozen possible tipping points".

  From the article first paragraph "with temperatures set to punch through the critical 1.5 degrees Celsius *threshold* by the early 2030s, a decade earlier than anticipated just three years ago."

So, if 450 ppm is bad, wouldn't 900 ppm be worse? It wasn't so long ago in the climate's history that it was that way. Not so long before that, it was 1800. Wouldn't that make the world ultra-XXXL screwed beyond belief? What happened there?

      Please let me know if you find anything in there that actually addresses the fundamental issue I raised about these alleged tipping points, rather than just being a pile of links that appears to a casual observer to be contradictory evidence.
