Peter KalmusSo far, 27 years of COP meetings have been a complete failure; you can't argue with physics. Anyone saying otherwise has fossil fuels or books to sell. #EmergencyMode
ArneBab@ClimateHuman Do you have the raw data of this? I’d like to try fitting an exponential to the curve before 1990. It looks suspicious.
@ArneBab What do you mean? btw I fitted an exponential to the CO2 fraction curve in my book ("Being the Change"):
@ClimateHuman That’s an exponential fitted to the whole curve. Do you see how this does not actually capture the time between 1960 and 1990 very well? It appears like between 1960 and 1990 there was a more rapidly rising exponential and it somewhat levelled out after 1990.
