Just US $250 billion per year to offset ALL of humanity's carbon emissions. Yes I said ALL. It would cost less than the ongoing 'war on terror.'

Since it's a natural process I think it has less chance of unintended consequences compared to something like putting aerosols in the sky to block sunlight. Just like Elon Musk's plan to put humans on Mars there's going to be tons of problems, but it makes sense to start working on it now so we can come up with solutions.
