In this formula which represents the decay of a pulse of CO2 with time t the first constant ao has a value of 0.217. The point about this IPCC formula is that as the first ao term is a constant the CO2 level will always go up and never down! This was first raised by Dr Jonathan Drake a UK climate researcher at the Edinburgh meeting with Professor Murry Salby as part of his recent UK tour. However as Dr Drake and Mr Alker of PSI pointed out all records of atmospheric CO2 concentrations past, proxy or present day observations show that CO2 varies both up and down on any time scale relevant to climate! So this formula invented by the IPCC allows them to claim wrongly that CO2 will always increase. How convenient for the apostles of man made climate change!
