Tamino,

For all your pretty graphs aren’t you missing something here?

The Mauna Loa, et al, figures show a roughly steady increase in atmospheric CO2 but there has been a massive increase in the burning of fossil fuels since 1990, especially, but not restricted to, India and China.

This huge increase is not being reflected by the Mauna Loa figures.
