Indeed, unless a new technology is shown to substantially deviate from the efficiency frontier in Fig. 3, it is reasonable to assume that the second - law efficiency
of an air capture system could be below 5 %.

Above: Negative - emissions solutions can include use
of natural
systems (e.g., forest or other ecosystem restoration, agricultural soil carbon sequestration) and technological
systems (e.g., bioenergy, direct

In principle,
capturing carbon dioxide from the
air (pdf
of the Keith et al paper) and burying it in the ground could give you whatever radiative forcing you wanted; the limits to such a scheme are entirely economic, rather than being imposed on the earth
system.
There are lots

system could do
air capture with CO2 compression at a cost well under 200 $ / tCO2.
But this upper - level

of the coastal low, causing the storm to be
captured by the upper level
air flow, like a spinning figure skater balancing another on top
of them.
CDRMIP experiments are designed to address questions concerning CDR - induced climate «reversibility», the response
of the Earth
system to direct atmospheric CO2 removal (direct
air capture and storage), and the CDR potential
of proposed schemes such as afforestation / reforestation and ocean alkalinization.

system operates motorized awning windows and dormer windows to
capture the prevailing breezes, automatically shifting the building between natural ventilation,
air conditioning and heating.
