A new satellite study of rainfall suggests that in the last 20 years the intensity of rainfall has mysteriously declined a little in most places. This is despite predictions it would increase, and CO2 itself rising by 41ppm globally during the same period.
By 2001 humans had cumulatively produced 291,000 Mt of carbon from fossil fuels, and cement production, but by 2020 our total cumulative emissions amounted to 470,000 Mt. (CDIAC data). So from 2001-2020, mankind produced 179,000 Mt of carbon or 38% of all-time homo sapiens emissions. Converting pure carbon to CO2 that means humans have emitted 656,000 Mt of CO2 yet seen either a decline or no trend at all in rainfall intensity.
Global CO2 rose from 371ppm in 2001 all the way to 414ppm in 2020. All the scare stories we are shown daily of floods across the world are simply part of the weather we have always experienced and always will.
