I don't know if you realised, but you just told everyone how little you know about scientific research, at the same time as trying to use your knowledge of scientific research to make a point. It's rather entertaining for everyone else, but I imagine for you it's somewhat embarrassing. Let me help you for future times you insist on chiming in:
1) Yes, and? Oncologists research cancer, climatologists research the climate. Or should they swap every once in a while to keep you happy? Or is it this particular study? I have news for you - this study is duplicated many times the world over at the end of each year/start of the next. Of course climatologists are going to perform it.
2) Nope. Continued funding relies on society surviving. Extraordinary-payout-massive-awesomeness-funding would come from showing how climate change is not happening, as that will get you a Nobel prize, $1m, tenure wherever you want it, and funding for the rest of your days. Science LOVES upheavals, as that's where fantastic amounts of learning is found
3) Again, not at all. See 2)
4) Not even close. See 2)
The idea of science and scientists you are arguing against is indeed horrific, but as it only exists in your mind and the minds of people similarly disposed to you, you shouldn't worry about it perverting scientific research.
