The combination of the title and phrases like &quot;simulations using a mid-latitude climate couldn’t get the job done because the rocks didn’t weather fast enough&quot; did make me think initially that they were proposing using this as geoengineering to pull CO2 out of the atmosphere.<p>(But yes, that&#x27;s not what they&#x27;re saying.  And my guess is it wouldn&#x27;t be anywhere near worth it.)
