Atmospheric CO2 readings from the 1970s until today.

Yes we have done nothing but make the situation worse in a very short period of time.

A case could be made for a return to the economic levels of the 1980s 🙂 It would be interesting to know whether the level of economic ‘development’ in Europe in the 80s, if spread throughout the world, using contemporary renewables and so on, would still result in a reasonable level of CO2 in the atmosphere?
