> The studies differ on the timing of when that weakening began. Thornalley’s record, which spans those 1,600 years, suggests it started at the end of the little ice age, a period from about A.D. 1350 to 1850
So the weakening current started before the industrial revolution could have had an effect and well before any significant human caused CO2 and therefore was not caused by man.
