Could seaweed be the 'fastest and least expensive' tool to fight climate change?

> catastrophic loss of human population At the same time, the population has been booming to the point that close to half of the humans who ever existed are alive on Earth right now. This is a significant part of the current crisis actually.

I remember reading, admittedly in a couple of science-fiction books, that the estimated number of humans that have ever existed is about 100 billion. Was that estimate wildly exaggerated? Or has it been dramatically reduced in recent decades?

How? Unless you get a breakthrough with fusion, I just don’t see us finding the energy to make carbon removal feasible. You either need huge tracts of land to power forests, or massive amounts of energy from another source to do it with tech, and neither of those is going to be the easy fix people believe is coming.

There's a nice handy fusion ball in the sky; but that isn't sufficient for CO2 removal, and if we do have a genuine incentive to remove it, I wouldn't want to bet that the incentives stop at any particular level and thus would give equal a priori credence to us ending up with too much or too little atmospheric CO2 with such technology.

The probability that this will end up happening leaves me feeling glad to be mortal.

Wait? Is someone really planning to do it? I just read 'Termination Shock' and it was big plot point. Didn't think anybody would really do it.

Who are these greedy people exactly? “Being greedy” is having food on the table, a roof over my head, and a few nice things?

Being greedy is declaring the food and the house is yours, and kick everybody accordingly. Then you offer as little food as possible in exchange for 18 hour shifts of housekeeping

In the context of the post you're replying to, that's like believing there will be a miracle pill so you can eat whatever you want, however much you want, drink as much alcohol as you want, and the magic pill will prevent obesity, cancer, heart disease, and liver failure. And even if such a miracle drug did exist, if seems like the better solution is to simply lead a healthier lifestyle to begin with.

Fusion is the key. Replace all of our dirty energy, and produce enough surplus to sequester carbon. We should be pursuing fusion as if the survival of the planet depends on it…because it is likely that it does.
