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
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

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".

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,
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
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

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
