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.

> My hunch is there are not many who want to suffocate while trying to exist for shareholder value. Have you... read the news lately? You say it's not a matter of politics, but the politicians are absolutely trying to roll back the clock, push dirty tech, eliminate all environmental protections and regulations.

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.

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.

We'll have AGI not because the AI becomes smarter but because humans become stupider.

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 "focused activity" or "Information search" (up to some point)

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.

But looking globally, more and more countries seems to get it at this point, and at least move in the right direction, compared to others. The others will make themselves irrelevant faster than the others can reach a f…

One of the largest countries in the world, measured by size, population, economy, and military. If you hadn't noticed, the US can do a lot of damage to the rest of the world all by itself. And pollution does not respect borders. Global warming does not respect borders.

Obama takes credit for U.S. oil-and-gas boom: ‘That was me, people’ https://apnews.com/article/business-5dfbc1aa17701ae219239caa...

You have to be born yesterday to believe that Democratic leaders haven't merely hand-waved and virtue-signaled about global warming for decades. I realized this back in the 1990s.

Democrats have superior rhetoric, and they are less openly hostile, but their long record of doing nothing to help is unsurpassed. They will fiddle while Republicans burn Rome. And don't forget that Joe Manchin for example was a Democrat, one who dominated Democratic policy during the Biden administration.

And parking is abundant!

If you have the money for it. https://easypark.rs/news/cheapest-countries-to-park-in/

In the US, people bend over backwards to ensure that there is free storage for automobiles. And that housing and businesses are forced to include that expensive (parking spots can run into the 10's of thousands of dollars for some kinds of construction) amenity. Fortunately that's starting to change, but it is a big battle. And meanwhile, CO2 levels keep rising.

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

There's an oversimplified assumption here that the plants will be less nutritious, and so people will eat more calories to make up for the deficit.

I suspect the presence of protein, fats and sugars influence the hormone production regulating appetite far more than these changes account for. I would expect the same health issues to be affecting other animal species in just as drastic a measure as humans if it were true, and also that global obesity happened at a more uniform pace rather than coinciding with the introduction of modern western eating habits and lifestyles.
