“Several independent indicators show an increase in global warming from 1975 to 2003. This increase is mainly due to the increase in the concentration of carbon dioxide,” the academy said in conclusion to the report.
There seems to be no limit to the dissonance in the climate science community. Temperatures started warming in the mid-1970s because of the PDO shift.
It is completely irrational to blame the warming on CO2. Did CO2 suddenly change properties in 1975?
From 1940-1975, CO2 rose and temperatures didn’t.
From 1975 – 2000, CO2 rose and temperatures did too.
The only logical conclusion we can draw about CO2 is that it has been increasing in concentration.
