Reply to comment by yawaworht-a-sti-sey in An Arizona plant will pull CO2 from the air and trap it in concrete by captainquirk

Trees are a temporary reservoir that'll hold the carbon for about 50 years +/- a few decades. There's entire regions where trees are dying because the climate has changed too quickly for them to adapt.

The true natural carbon sequester is algae in a high sediment deposition area. If the algae is buried before their bodies decay or are eaten, the carbon can be captured indefinitely. This is the first step in how oil is formed.

Yeah, further up I said we're better off fertilizing the oceans or dumping sulfur dioxide in the upper atmosphere than doing this active sequestration shit when we don't have cheap abundant energy.

You might as well just give china and india free solar panels instead.
