You asked for a simple explanation it is the words you used –
you can read synonyms here and would you believe simple is not one of them
However the antonyms are ambiguous, indefinite, obscure, unclear, vague
which would seem to be your point 😉
If it’s so obvious, you’ll be able to provide us with a simple explanation of the proof that increases in CO2 concentrations are directly resulting in warming?
no its quite complex and the IPCC is a few hundred pages long. Still I more meant cause and effect alone made a good prima facie case. In essence [ you will have some fun with this] more i would need convincing it was not true rather than convincing it was true – can you convince me its not prima facie* true?
noting that global temperature has varied a lot more than the current warming we’re seeing
Everyone knows it has varied for other reasons, no one is saying other factors cannot alter the global temperature. It is a pointless point not in doubt
how do you tell if that’s not natural temperature change without also studying periods when we weren’t directly influencing the environment
Nice cherry picking of the data 😀
Of course we need a baseline I said that, its pretty clear [ for me] what i meant
* it is obviously utterly irrelevant, in matters of science, what either of us thinks prima facie tbh.
