Do you have solid evidence of these claims?
Heck I can't even challenge my own supervisors when they make swallow statements that are in fact contradicted by a bunch of papers, how could I get funding from external entities by submitting socially unpopular ideas? Impossible, especially in highly politicized fields.
And even if you did, it wouldn't disprove the consensus on climate change in any way. Or are you also saying that all the research was falsified? Any evidence of that?
