We've breached 430 ppm CO2.

@petergleick no wonder we all have hacking coughs.
Koch Political Operation Spent Nearly $550 Million During 2024 Cycle

The huge sum shows that while the Koch network may not hold significant power at high levels of the Republican Party, it remains a financial juggernaut.

@petergleick

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

Atmospheric CO2 ppm by year 1959-2024| Statista

The average global atmospheric COโ‚‚ concentration has increased by almost 20 percent since 1990, and set a record high in 2022.

@petergleick So weโ€™re rushing into territory where human cognitive capabilities measurably suffer, arenโ€™t we?

Within a few decades, driving a car with the windows rolled up will be dangerous.

@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.

@petergleick And its still going up.

@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
