Quote:We don't have measurements on short term changes before thermometers were in use. The proxy measurements are averages over 50 or more years. When you look at thermometer measurements, the changes that happened between 1910 and 1940, before CO2 enrichment, are the same as those from 1980 to 2010.


 

CO2 has SOME effect. Nobody (well very few) disagree with this. All other things being equal, a doubling of CO2 will increase global temperature by 1.5 degrees C. The disagreement is in the 'other things.' The Warmists claim that 'other things' will amplify the warming (positive feedback). The skeptics claim that 'other things' will limit the warming (negative feedback).

 

Forgive me, it's been a while since I really read anything on this thermometer arguement...  So there was no measurements of temperature before 1910?

 

And I'm glad you admit that burning carbon has some effect on climate changes.   The concept of a negative feedback loop within the enviornmental system is something I remember from my college days in ecological biology.  My professor, who is pretty well known in his profession discussed these feedback systems.  At some point, the system becomes over-run and cannot compensate anymore.  That's the thing.

 

See, now that you admit that there is an issue, you should realize that the negative feedback loop is not the savior if we continue on the same trajectory of burning that we currently are on.
