No alternative to atmospheric CO2 draw-down
This article suggests that the current atmospheric CO2 level is already
triggering amplifying feedbacks from the Earth system and therefore, in
themselves, efforts at reduction in atmospheric CO2-emissio
Chris and list:
1. Thanks for forwarding your interesting 4-pager on marine engineering. I
respond here only from the perspective of biochar.
2. On your p 2, the word "biochar" appears this way:
"Depositing crop wastes on the deep seabed – Strand and Benford (2009) have
proposed depositing
As previously pointed out on this list, monsoon disruption and ocean
acidification are not widely accepted as being the certainties claimed

1. This note is to draw attention to a nice April 2011 comparison of different
CDR approaches that I had not seen before being sent to it by Chris Vivian.(see
below). For about 25 minutes of Ken Caldeira comparing most of the CDR

Hello Chris et al.
I think this is a very interesting paper.
With respect to Marine Cloud Brightening (MCB), outlined therein, I would like
to add a couple of points:-
If MCB is found to function as assumed in our modeling studies – which remains
to be determined – it could

It is frankly somewhat amazing that this review contains no mention at
all of what appears to be the single lowest cost and lowest impact way
of removing excess CO2 from the atmosphere, namely the accelerated
weathering of magnesium silicate bearing rock by spreading the
pulverised rock at la
