It may be your point, but it wasn't mine.
I was talking about the CO2 level.

Sigh Go on then, make your point about CO2 levels again, I'm
loosing interest. But I would like to know how they measured CO2
levels 100 years ago - and indeed why they would have bothered.
You also claim they measured them in 1959 - same question applies.

I'm afraid you are showing a lack of knowledge of scientific
history. 100 years ago, ie in 1909, it would have been a classroom
exercise to determine the composition of the air.
Every chemistry schoolbook would have given the figures.

I'm afraid you are showing a lack of knowledge of social history.
Education wasn't even compulsory until 1918, so I'm bloody sure they
didn't have fully equipped labs with air quality monitoring
equipment.

I don't see what universal education has to do with it.

Your claim, as far as I can see, is that it would have been difficult
to measure CO2 levels in 1909.

I'm telling you that it would have been a trivial task
in the chemistry department of any university at the time.

Oh? A while ago it was; "100 years ago, ie in 1909, it would have been a
classroom exercise
to determine the composition of the air. Every chemistry schoolbook would
have given the figures".

Now its " a trivial task in the chemistry department of any university at
the time".

Typical ecobollox. Change/ignore the facts if they don't support your
cause.

Exactly who measured & recorded the figures showing "There is overwhelming
evidence that CO2 levels have been increasing over the last 100 years"?
