#climatechange@petergleick So we’re rushing into territory where human cognitive capabilities measurably suffer, aren’t we?

Maybe if you turn the graph sideways

@petergleick for planet it's nothing. humans are no more than ants and threaten nothing but themselves.
@Abdulzefir @petergleick I think dodo birds would argue otherwise.

#climatechange@petergleick yup. 870 ppmv is getting mighty close with that gradient.
This from 2023:
"...That would be edging close to the average CO2 concentrations (870 ppmv) associated with huge crashes in marine biodiversity over the last 534 million years, according to a study published June 22 in the journal Earth's Future..."
19 'mass extinctions' had CO2 levels we're now veering toward, study warns
The research looked at peaks in biodiversity loss and their relationship with atmospheric CO2, finding 50 events over the last 534 million years that can be considered mass extinctions.

@petergleick my brain catching up with what i read today before bed...
Oxygen levels can be increased by nuclear reactors... but that isn't really a solution because it does so by electrolyzing water. It's too late for me to math, but glancing at estimates isn' giving me high optimism, particularly against thst gradient (and implicit ratio of atmosphere is in that ppmv)...
We need to STAHP BURNING DA STUFFS.

#climatechange@petergleick the problem isnt' the absolute value of 430pm (or in future much more) becasue millions year ago it was so much higher.
the real problem is the rapid change: animals and environments hasn't enought time to adapt

@Nick44 Oh yes it is the problem. Millions years ago humans DID NOT EXIST.

@efialto humans can live with higher co2 concentration, we van adapt. Animals and plant dont and we're losing biodiversity, not human beings
