Re: 30m quid on removing greenhouse gases?
Well said, Jimmy. There is the organic carbon cycle, CO2 -> plants -> animals -> CO2; and there is an inorganic cycle, silicate rocks -> carbonate rocks -> silicate rocks. The inorganic cycle is vastly greater than the organic cycle, driven by geophysical processes.
Our burning of coal and oil is merely a part of the organic cycle, and has a negligible effect on the overall carbon situation. Sea level has risen some 300 feet (ca 90 metres) in the last 200 centuries, but industrial carbon burning has been only in the last two centuries. Most of the sea level rise came before the industrial burning.
That proves your point, Jimmy, that things are not well understood.
