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"):
@ArneBab The raw CO2 fraction data is easy to find online. I posted a link to the global mean surface temperature data (above)
@ClimateHuman I now checked that myself with the mauna loa data. Took a while to get gnuplot to behave …

As you can see, if we had continued as we did before 1989, we’d now be at a much worse place.
@ClimateHuman (though this does not prove that it was the conferences that achieved that)
@ClimateHuman What it took for gnuplot to behave (see the image description for the code):
