For the last 10-20 years or more, a few of us have been saying that the IPCC has been ignoring the elephant in the room…that the real climate system is simply not as sensitive to CO2 emissions as they claim. Of course, the lower the climate sensitivity, the less of a problem global warming and climate change becomes.
This elephant has had to be ignored at all costs. What, the globe isn’t warming from manmade CO2 as fast as we predicted? Then it must be manmade aerosols cooling things off. Or the warming is causing the deep ocean to heat up by hundredths or thousandths of a degree. Any reason except reduced climate sensitivity, because low climate sensitivity might mean we really don’t have to worry about global warming after all.
And, if that’s the case, the less relevant the IPCC becomes. Not good if your entire professional career has been invested in the IPCC.
