Similarly I don’t know the authors of the pieces or their qualifications to interpret either the base data or the adjustments.
I do know that a ‘full disclosure’ of the raw data to the uninitiated or poorly qualified could be like asking a plumber to explain the full and detailed workings of the Hadron collider.
And I would hope that the kids at the Science Fair are aware that there is no ‘proof’ in science. Science moves forward based on hypothesis and probable explanation. The scientific community is its own forum within which certain explanations gained more or less credence as time goes by.
Explanation previously held as true becomes superseded by newer truths (from Newton to Einstein to Pauli). Perhaps not consensus but near enough to it as makes no difference.
I can remember year after year winter snow in Liverpool. I went to a wedding in Zurich in December about two years ago - not one flake, in the sky or on the ground.
As for one or two degrees being good, tell it to the birds - literally, the ones dying out because spring is coming too early and insect larvae are peaking too soon to feed the chicks. Not a joke.
Or if you don't believe CO2 emissions are the cause, you can laugh about it with those affected by lack of water availability, flood risk, rising sea levels, storms and disease transference.
