>>Actually annual global CO2 emissions trebled between 1900 and 1950. I would say that was significant. A quick google will provide the figures. Make a bit of effort.
around 15 ppm rise in atm CO2 that period and about 0.4 degrees followed by about 3 decades of cooling from 1950 onwards. Over 100 ppm rise overall.
I buy the climate is changing thing and we are contributing. Just don't buy the complete demonisation of CO2. It has an effect for sure. I just don't think the lever is that good. i.e. it isn't the major driver - if at all. It may well be that temperature is what drives CO2, not the other way around...
