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

If we were only eating plants then there would be no obesity crisis.

You'd be amazed at what you can do to yourself with enough fried potatoes and refined sugar.

"Yes, the planet got destroyed. But for a beautiful moment in time we created a lot of value for shareholders.“

Clean tech will save the day (low carbon generation, batteries, electrification trajectories and rate of change, broadly speaking), but the global fossil industry will need to be dismantled faster than some will like. It is a matter of survival, not politics or economics. My hunch is there are not many globally who want to suffocate while trying to exist for shareholder value.

Nuclear will save the day in combination with clean tech.

Clean tech on its own is too slowly to be meaningfully impactful by the time we need it.

You do us all a disservice by saying “the politicians”. The REPUBLICANS are attempting to ignore reality and burn more fossil fuels. Nobody else in America. Name the problem, otherwise you’re implying it’s a bipartisan effort.

We need to push for clean tech obviously. I disagree with Republicans blocking wind farm construction and rolling back regulations, but American energy independence is important for national security, which is a shorter term issue than climate change. And developing more domestic clean energy helps with that as well.

But everyone wants everyone else to suffocate while delivering shareholder value for themselves. Classic Prisoner's Dilemma.

Never heard this take before. Care to elaborate? It seems like crop failure and disease are the typical causes of food shortages, if not outright human logistical failures. Sounds like saying pouring gasoline on a tiny fire is the only reason we aren't cold (ignoring that more firewood would be the solution). An unsustainable solution is not in-fact a good solution. So if your assertion is correct, then we should all prepare for our thatched huts in which we will starve.

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.

CO2 increase of 400ppm decreases cognitive function by >20% [1] I frequently send this medium article [1] to friends + family for a basic dive into how CO2 affects our thinking and abilities at various levels in common areas. The article cites a study [2] which graphs cognitive score for different activities at different CO2 concentrations. Each activity's cognitive score is worse at higher CO2 concentrations, EXCEPT…

That article really needs a pre-and post fixing his house.

I find it hard to believe that stat you provide -- seems like a bit of a shiny lure without much merit.

Maybe if CO2 PPM wasn't so high I could make sense of it.

> 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.

Chronic exposure to CO2 levels above normal but below acute toxicity makes us dumber and more irritable.

Furthermore, yes, getting to the point where we're no longer starving and in thatched huts did require fossil fuels, but now we know what they do, and that they're actively having an effect on the environment, and clearly us, are we so stuck in our ways we can't change our actions to secure a life for those that come after?

Exactly. As a Democrat my eyes were opened when I saw the senior leadership do absolutely nothing to impede Trump other than form a strongly worded tweet.

I'd be willing to bet they go the Spaceballs route and make cans of oxygen a must-have item before they cut the emissions.
