RE: [geo] The Carbonate Solution, Part 2:

That was some positive comment on my olivine concept. I would like to react to one sentence, about the spreading of olivine over vast areas, preferably in tropical climates. Why not by this rather crazy idea? Cheap transport of olivine? Transport costs for olivine can be fairly high. Tropical co

RE: [***SPAM***] Re: [geo] The Carbonate Solution, Part 2:

You can’t steer the wind but rivers always go in one fixed direction and in the wet season you know where they will spill over. Dropping your olivine in a river is much easier and better controlled than trying to get a load of fine grains to be carried away by the wind in a controlled way , and

Re: [geo] CDR as Mitigation

I agree with Dr Burns, the conflation of CDR with mitigation is problematic. It is both more logical and more politically expedient for CDR to be referred to as "restoration" or "remediation". -- Adam Dorr University of California Los Angeles School of Public Affairs Urban Planning PhD Candidate a

Re: [geo] CDR as Mitigation

CDR reduces net emissions. What is the difference between a coal plant with CCS and a bio energy facility without CCS versus a coal plant without CCS and a bio energy facility with CCS? Why should the addition of CCS be considered mitigation in the first case but not in the second case? On Wed,

Re: [geo] CDR as Mitigation

I like to think of this question in terms of partitioning of the planet's carbon stock. Global carbon is divided into two reservoirs: the lithosphere (rocks and fossil fuels) and the biosphere (soil, biomass, oceans, atmosphere). While some climate disruption is presented by transfers within the

RE: [geo] CDR as Mitigation

Dear Ken, I don’t agree that CDR reduces “net emissions;” rather it seeks to reduce the net amount of carbon stocks in the atmosphere. That can have profoundly different results than actually reducing GHG emissions, if: it simply results in displacement of emissions in other places due to ongoi

Re: [geo] CDR as Mitigation

Ken et al.  Perhaps the difference between fossil CCS and BE CCS is intent(?) If BE already exists and CCS is added, then that's CO2 mitigation(?) If BECCS is installed specifically to generate C negative energy, then that's CDR restoration or remediation(?) While on the subject of semantics, ho
