“The generally accepted view that the recent rise in CO2 is mostly due to human activities is supported by comparing the proportion of the isotopes of carbon in the atmosphere between earlier and later periods. The proportion of human-produced carbon isotopes – ie produced by burning fossil fuels – has increased over the past 150-200 years and is still increasing.”
What kind of scientific term is “mostly”? Can tbat be expressed as a precise percentage? Can it be sourced? It is tbe very crux of tbe argument.
