Consumerism is the problem. If fossil fuels were used on necessities sure. Single use plastics, individually packaged consumables, planned obsolescence are examples of things that are not necessary. These examples have all to do with shareholder value.

Consumerism is not the problem. Human beings don't stop wanting to improve their lives once they have the bare necessities and there is nothing wrong with this . We can have our cake and eat it, we just need to transition to cleaner forms of energy. Which we are doing.

> there is nothing wrong with this

Look at the headline. Res ipsa loquitur.

They told us to deny the evidence before our very eyes.

I remember when I first saw an oxygen bar at a mall and thinking how stupid it was. Fools and their money...

But who's laughing now?

A few years old now, but still worth checking out: * https://en.wikipedia.org/wiki/The_High_Cost_of_Free_Parking

Grabar's book that I linked below is probably more accessible to most people, but Shoup is of course the OG.

I think you have that backwards. Building nuclear is slow slow slow. I can have new solar on my rooftop this year.

While that is true that there is a lag time to deploy nuclear - that is a vestige of the last 40 years of regulating it out of existence. That has changed - technology has improved and regulatory is under scrutiny. The difference is that once nuclear starts to roll out, as it will in the next 3-5 years, we will be seeing large deployments of clean dedicated load ripple through our electrical system in a product assem…

The regulatory regime also affects large scale deployments of solar.

> Humans evolved in an atmosphere containing roughly 280–300 ppm of CO₂. The average annual increase over the past decade has been about 2.6 ppm per year, with 2024 recording a 3.5 ppm rise. So currently we're at 428 with 3.5 increase per year, yeah, that's scary if it doesn't slow down soon. Makes you wonder about what indirect health side-effects that could have on us.

Exercise rises CO2 levels in blood and there are specific exercises to increase CO2 tolerance. Also, extra ventilation during very long exercises (hours) lowers CO2 blood level.

As the recovery from aerobic and resistance exercises also increase ventilation, I think we should just train a little more.

Higher carbon dioxide makes us dumber: https://pmc.ncbi.nlm.nih.gov/articles/PMC7229519/ I wonder how long before in-home CO2 extraction becomes a thing.

I have friends that fell down air monitoring rabbit holes in the situation of the early 2020s and one of the things they have remained obsessed about is home CO2 levels and have active monitoring equipment and "pager alerts" and other things setup. Home carbon capture is sort of a thing already: buy more houseplants, keep them alive and healthy. Though the most common home interventions for now are still "open a wind…

House plants make too minor a difference to be worthwhile.

Opening windows is better but if you want a more energy efficient solution you should invest in a HRV/ERV

Plants grow faster (but not better) with more Co2 I wonder if this could be related to global obesity ?

That would work if obesity levels increased equally across the globe. But even if obesity does increase globally, there are very wide disparities. Contrary to popular belief, there US is not the world.

You do the people causing this problem a great service with false equivocations like this. It is clear one group would prefer us to ignore the problem and do nothing at all - in fact encourage the problematic behavior - and the other would very much like to take action on the issue if they had the political power.

> the other would very much like to take action on the issue if they had the political power. They had political power! During the Biden administration, during the Obama administration, during the Clinton administration. Al Gore is a famous environmentalist... for making a movie after he was out of power. What the hell did he do for the environment when he was literally in the Oval Office, at the side of the Presiden…

The Biden admin did try to make large-scale investments in renewables and policy changes to encourage the energy transition in the US. The situation at the end of the admin was far better than when it started.

Why are you using a tone that implies that's not the case?

To my understanding, as with most carbon sequestration efforts, house plants are a long-term planning horizon solution. Filling your house with plants won't fix your biggest spikes in the CO2 in your home, but they'll lower the overall floor/median/average over a large enough span of time (months to years).

Relates to the long running "joke" that the best way to sequester CO2 today is to plant new growth forests 50 years ago.

I'm not a doctor, but I reckon it'd be same as any other case of carbon dioxide poisoning.

It makes us dumber and dumber.

No word from the Cincinnati Clinic though...
