An interesting analysis. It seems to stop just short of attempting to answer the really important questions, though. For example, it says:<p>> This is based on a 2017 UNEP report that estimated we’ll need annual CDR of 10Gt will help achieve a 2°C scenario.<p>and:<p>> The average cost is $332 per ton<p>So currently the annual cost to keep to that scenario is about $3 trillion per year. To put that in perspective, it's about half the amount that Covid-19 is thought to have cost the world in 2020 according to one estimate.[0]<p>It's possible that the costs of CDR will go down as the technology scales up, but it's also possible that a relatively short economic stress like Covid-19 is easier to manage than a multi-decade commitment to funding CDR at a level like $100 billion per year, for example.<p>[0] <a href="https://www.standard.co.uk/business/economy/how-much-has-the-pandemic-cost-the-world-s-economy-b473369.html" rel="nofollow">https://www.standard.co.uk/business/economy/how-much-has-the...</a>
