"Atmospheric carbon dioxide had been in decline until the advent of the industrial revolution and the burning of fossil fuels.Had that decline continued, long before now the level of carbon dioxide in the atmosphere would have become so low that it would not have supported plant life."
hang on, are you saying that unless we had the industrial revolution and started burning coal and other fossil fuels, CO2 would have dropped to such an extent that in 2020 the earth would have no plant life?
Really, is that what you're saying?
so we've had billions of years of continuous life on Earth but if not for the extra CO2 in the atmosphere we'd once again be a near lifeless rock?
where on Earth do you dig up this rubbish? You'r a twit.
