What is the base-line that you greenies have used to come to the conclusion that there is an anomaly in the first place?
It's not a single base line...there's many. That's what makes the findings of climate scientists robust, it doesn't depend on one baseline...
There's the airborne fraction of carbon dioxide, the atmospheric concentration of carbon dioxide, methane, the spectroscopic measurements of the carbon isotopes in the atmosphere, the top of the atmosphere radiation flux, the ground temperature record, the satellite temperature record, ocean heat content, ocean pH, water vapour, the ice cores, the mud cores, foraminifera, cosmogenic isotopes, sea ice loss, glacier mass balance, total solar irradience, the changing temperature profile of the atmosphere, the paleoclimate records of change. That's
some of them.
You are obstinate in your focus on one variable at a time. That why you will
never see this clearly. You have to bring all of these strings together to make attribution possible. Because, the scientists have found what happens when different climate forcings are changing.
It's a diagnosis. Doctors, engineers, scientists, mechanics, electricians, all sorts of professions make diagnoses based on the symptoms.
