@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
@petergleick And its still going up.
@petergleick yup. 870 ppm is getting mighty close with thst 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..."

@petergleick So we’re rushing into territory where human cognitive capabilities measurably suffer, aren’t we?
So what? Imagine you're a kid: grown-ups scream your car exhaust (CO2) melts the Earth like ice cream. Bad science! CO2 feeds plants, greens the planet, boosts crops. It's just 0.04% of air—doubling it won't boil us. Earth was hotter with more CO2; life boomed. Storms? Always happened.
Jobs hoax: Kills coal/oil gigs for wind/solar (fewer jobs, pricey, fragile). Elites hike energy costs, empower China polluters. Fossils lifted us—use smart, keep working. Don't panic; question it!
@petergleick for planet it's nothing. humans are no more than ants and threaten nothing but themselves.
Emissions keep going up, and more and more of the planet continues to be pillaged, poisoned, razed or paved over. The insects are dying. The animals are dying. The plants are dying. The soil is dying, which happens to have twice as much carbon and water in it relative to the vegetation on top so the productive capacity, the biomass, is collapsing, along with the hydrological and carbon cycling this implies. And these crazy huge dams which turn countryside into methane
The fossil fuel industry is funding an extinction level event.

@petergleick no wonder we all have hacking coughs.
