One theory is that it's too early in the cycle to attribute the warming to El Nino (which will make things even worse), but that it's due to a reduction in SO2 in shipping fuels causing lower solar reflection and heating up the oceans faster.
Decades of optimism along the lines of "something bad is coming, but we can still fix it" did way too little.
Perhaps now that it's actually bad something might happen.
At this point, geo engineering is probably the safer option compared to letting the planet spiral into an uninhabitable waste land. Of course, it should be combined with cheap and abundant renewable/nuclear energy.
Now that things are bad, there might actually be popular support for this, though we may still have to wait for the current political class to retire.
When I was in university around 15 years ago, the idea of peer-to-peer currency was floating around as an evolution of the tit-for-tat idea in BitTorrent, which was still popular at the time.
The expectation back then was that peer-to-peer would continue to evolve, especially in the area of distributed computing. Clouds did not exist yet, but projects like SETI@Home were having some success in terms of sharing compute resources. A peer-to-peer network could meter you for your consumption of compute resources through a lot of microtransactions in a virtual currency that avoided traditional banks or credit card providers.
Then came the first and least efficient implementation of peer-to-peer currency: Bitcoin, which did not sell the distributed computing capacity, but used it to do meaningless computations. It was clever, since up until that point the problem of zero-cost identity had been unaddressed, but appears to have few practical applications. It is surprising to me that people view it as some kind of alternative currency or store of value and send real currency to "trusted" exchanges. You deposit money just for the pleasure of doing a transaction? Yeh, sure, you don't need to agree on a global, trusted intermediary, but you still need to trust your exchange not to screw you over.
Ethereum is closer to the original ideas behind distributed computing and peer-to-peer currency, but the Internet has largely moved on from peer-to-peer networks. Today I can instantly get all the compute resources I need in a trustworthy, secure environment, and only pay for what I use. BitTorrent has also lost a lot much of its relevance with streaming services providing a greater level of convenience.
However, it's hard to be sure. A discussion: https://atmosphere.copernicus.eu/aerosols-are-so2-emissions-...
