Using this, how fast could we capture, say, one ton of carbon? If we wanted to return to 1950 levels, how many years per giant pond of microbes would we need?<p>The article is lacking data:<p>> There will be circumstances where the tree is going to outperform microbes or fungi. But there will also be circumstances where you really want a fast-growing aquatic microbe that sinks,” [Tierney] said.<p>The project website is similarly light. <a href="https://twofrontiers.org/expeditions/vulcano" rel="nofollow">https://twofrontiers.org/expeditions/vulcano</a><p>Both those make it sound on par with current approaches, not 'extraordinary'. If anyone knows more I've love to see some back-of-the-envelope math to see how useful this really could be.
