It's a fundamental nonsense to dismiss Climate Science based on sources of funding, especially if you don't apply equal scrutiny to the chief sources of opposition and who is funding them. It's pretty well-known, for example, that CFCs both wrecked the Ozone layer and also contributed to Climate Change in like manner to CO2 emissions -- and it doesn't take a genius to realise that the reason nothing was done for so long was because the companies who sold this compound had a massive vested interest in hushing up that science, or funding politicians to block it. Ditto Lead in petrol, etc., etc.
It takes virtually no time at all, then, to trace opposition to Climate Change back to the vested interests that are Oil Companies, and so on, or to draw a link, to take another example, between Trump's general philosophy on Global Warming and his support for increasing Coal production in the US.
I don't particularly want to go too far down this road, but it's an errant nonsense to criticise Climate Science for being the product of vested interests. And the fact remains that the raw data is far more in-depth and solid than you are giving it credit for.
