I would say most scientists on either side of the issue aren’t intentionally skewing their data for profit. The issue is that they have preconceived notions about their subject and choose data that supports those preconceived notions. It’s a self fulfilling prophecy, if you think climate change is a huge problem then you’re more likely to subconsciously disregard data that contradicts that point of view. Also, if you think global warming if full of crap, you go looking for data that proves that point even though there may be evidence that shows GW is happening.
Some researchers do cherrypick data to support their hypothesis intentionally but I don’t think that is the majority of scientists. The problem is that climate change has become a part of our left vs right power struggle. It is dogma for the left and absurd to the right.
In reality we’re talking about possibility the most complex issue man has ever investigated. Countless factors play into this including the earths rotaion and orbit, the intensity of the sun’s radiation , trends in water vapor, carbon dioxide and other ghg’s, transformation of farmland and forest into urban concrete, the Gulf Stream, ocean currents, the overall albedo of the earth with the changing surface of the earth and on and on... Billions of data points feed into what is really happening. This issue is so complicated that if someone tells you they know for sure it is or is not happening , they are delusional, a fool, or are trying to further an agenda with no regard for the truth.
