I have provided below excerpts from a paper on truly organic chemistry.
That paper provides a method to convert carbon dioxide into feedstock
for chemical synthesis and for fuel The use of carbon dioxide in that
way may not be as potent as photosynthesis but it does provide a
potentially important contribution toward re reducing carbon dioxide in
the atmosphere. Since global warming is a dire threat the kind of truly
'organic' chemistry should not be ignored.

Synthesis of b,g-Unsaturated Acids from Allenes and
Carbon Dioxide
Michael North Angew. Chem. Int. Ed. 2009, 48, 2 – 4  2009
"There is increasing interest in the use of carbon dioxide as a
starting material for chemical reactions.[1] The main reason for
this interest is the widespread acceptance that rising atmospheric
levels of carbon dioxide are directly responsible for
global warming and the associated climate changes.[2] If waste
carbon dioxide produced by major fixed-site producers, such
as fossil-fuel power stations, oil refineries, ammonia plants,
and cement works, could be converted into feedstocks for the
chemicals industry, this would not only reduce carbon dioxide
emissions, but would also provide a new revenue stream for
these industries. However, the raw material for almost all of
the chemicals industry is currently provided by less than 10%
of the output of an oil refinery,[3] the remaining output being
used as fuel. Thus, even if the chemicals industry could utilize
carbon dioxide as its only starting material, the maximum
achievable reduction in carbon dioxide emissions would be of
the order of 10–20% (taking into account that the chemicals
industry currently uses both chemicals and energy produced
from fossil fuels). This figure would, however, be considerably
higher if carbon dioxide was to be converted into chemicals
for use as fuels as well as building blocks for the chemicals
industry.[4]"
"transformation illustrates that it is possible to
use carbon dioxide as a starting material for the synthesis of
highly functionalized products under mild conditions. It
should help to dispel the myth that carbon dioxide is too
thermodynamically and kinetically inert to be a useful
chemical feedstock."
