If it is accepted that CO2 is an effective greenhouse gas then I think
the images presented in the following link tell an extremely worrying
story.

Yes, it's very interesting comparing the different timescales.

This is sobering as well. Global CO2 emissions rose from 24b tonnes in to 36b tonnes now

In particular CO2 produced by cement production seems out of control, 53m tonnes in 1950, 1.5billion tonnes now. Thanks largely to grand projects by governments pledged to become carbon neutral.

In fact Britain 4 biggest construction projects (Hinckley, Crossrail, HS2 & one other which slips my mind) will, if ever completed, emit roughly the same amount as a city the size of Birmingham, or what 19 million Malawians emit in a year, just solely from the cement used!

Trouble is the timescales involved are of little concern for politicians elected for 5 years.

Fortunately the main absorption lines are already saturated so that the
heat retained as CO2 concentration increases scales with log(CO2_ppm).

Even so it is disturbing the thermal equilibrium in a way that takes
time to have the full effect so we haven't yet seen the full warming
effect of all the CO2 concentration presently in the atmosphere.

It is also interesting to see how the effect of land mass and industry
distribution affects CO2 concentrations with latitude.

In the far north midsummer CO2 concentration has maximum deviations as
the forests photosynthesise 24/7 whereas at the south pole the annual
variation is almost completely smoothed out by atmospheric mixing.

South pole and southern hemisphere concentration also lags behind the
north (where the bulk of the heavy industrial nations are).

'Production' of CO2 seems to have slipped out of control. The
inevitable consequences are being locked into the ocean/atmosphere
system. The changes to the world's climate that are now becoming more
apparent are bound to continue. Some of the effects will probably be
good but most will be bad. As I have said before - interesting but
worrying times.
