Because it’s a bandaid on an arterial bleed of a problem and has its own host of issues (anoxia once the algae blooms die off being one of the big ones, aside from the cost of actually doing it on a global scale). Lots of discussion around whether it makes sense to do, but really for the effort to do it, and the unintended effects on the environment, it would probably be better and cheaper to just reduce GHG emissions.
Well, why not? Any replacement power generation or transportstion systems will require construction and maintenence, just like any other project.
The actual choice, is
- we either act proactively, or
- our remnant ( if any ) regret, retroactively.
This isn’t consensus for a simulation/model, this is actual historical fact:
- Evolution of global temperature over the past two million years

They’re ignoring methane, and they’re stating, explicitly, that at our current atmospheric CO2, the planet historically stabilized at between +5C & +6C.
When one factors-in the added methane, 1.3ppm to 1.4ppm, at 82.5x factor, we’re actually between +8C & +9C planet-equilibrium-temperature for our current atmosphere.
-4C put 2 miles thick of ice on North America: planet-degrees are BIG.
Humankind simply is either too devoutly-ignorant or too stupid to live, from the looks of it.
After it has happened, oh, then humanity’ll admit it ought do something…
Utterly retarded, and the obliteration-of-billions-of-lives it is setting-up the enforcing of, is needless.
