The evidence is clear that something is wrong with the above claims.


The ratio of carbon isotopes C-12, C-13, and C-14 found in fossil fuels and
the ocean are known and provide tell-tale "signatures". The ratio of those
carbon isotopes in the atmosphere have been measured with respect to time
and the isotopic evidence indicates the increase of carbon dioxide in the
atmosphere is most probably due to the burning of fossil fuels.

(The first person to use isotopic ratios to determine the source of
atmospheric carbon dioxide was Hans Suess as far back as 1955. In
particular, the dilution of C-14 due to fossil fuels is known as the Suess
Effect.)
