1. “one of the most important sentences of the last few centuries”…
Did the IPCC SR15 change the debate, the IPCC just in the right place at the right time, or are some people just slow to get it?
Seriously...

2. Why not put praise on the earlier Paris Agreement, which has a legal form & is the text countries agree to adhere too?
Perhaps many just do not know about the Paris Agreement (or was it Accord?), or confuse IPCC SR15 and Paris?

3. Scientists have been on net-zero for years. So have policy makers. The Paris Agreement did not happen in a vacuum, nor IPCC SR15, it built on the work over years, even decades.
IPCC SR15 is an assessment of the literature, not new science. Or is it?

4. IPCC AR5 was onto it...
Remember all those scenarios below zero, & complaints about BECCS?
And remember the high profile “carbon budget”, figure SPM10, that build on papers from 2009?
We knew about net-zero then...

5. Back in 2012 the Nordic countries were aiming for net-zero (carbon neutral) by 2050 (sorry, link is dead). It wasn’t cool then, no leader boards of x% of countries with net-zero targets… https://twitter.com/Peters_Glen/status/271859710653763584
6. @Oliver_Geden was writing about net-zero (carbon neutral) in 2010 https://www.swp-berlin.org/en/publication/climate-two-degree-target/
His 2016 article is more influential than many will give him credit https://www.nature.com/articles/ngeo2699

7. Even before the big carbon budget papers in 2009:

8. Why weren't preeminent fossil energy experts lumping praise on IPCC AR5, earlier reports, early movers, & leading their industries out of fossil fuel dependence?
It is almost like people forgive GM for doing an EV ad...

9. The quoted IPCC SR15 text is great. Sharp, crisp, & I use it all the time. Hats off to the smart people that wrote it...
Though, we have known more or less the same for 20+ years, & failed to act.
And we are still failing to act...

10. I am not sure the IPCC focused on the net zero text anyway.
My favorite was: “Every bit of warming matters, every year matters, every choice matters”.
While not as catchy & more ambiguous, it will probably stand the test of time!
