From David Ho
A constant reminder that even if CO₂ emissions decreased annually as much as they did during the pandemic lockdown from now to 2030, we still wouldn't meet our emission target to keep global warming below 1.5°C.
To get to real zero (let's stop calling it "net zero" because we all know that carbon offsets don't work) by 2050, emissions would have to fall by 9% per annum. Actually, that's not even to real zero; that's to a 90% reduction from today. Calculating a cumulative decline involves using exponentials, and they don't work to zero. What about if we target a 99% decrease by 2050? We'd have to cut emissions by 17% per year.
Just a reminder: emissions are still rising. And the rise in temperatures is accelerating.
