If you don't believe that people in science can't go corrupt then you don't understand the nature of human beings. I'll give one example. Almost 2 decades ago Merck came out with a drug called Vioxx & raved about it. As it turned out a lot of people got hurt by that drug & it was yanked from the market. Moral of the story, yeah no one is ruled out in getting greedy. Merck has had to work hard in building back their reputation. This is why integrity in hiring is necessary in Big Pharma. In the current vaccine trials, even in the trials, the companies noted if there was a major stumbling block & adjusted their time line as such. Many examples from science: red dye #2, saccharine, glyphosphate, chlordane. DDT. I'm not saying all scientists are greedy & corrupt but we know from the history of mankind that temptation occurs. Again I choose to disagree with your opinion on global warming. I do not believe we have a runaway greenhouse effect. I believe certainly climate can change because of all the scientific processes involved, I just don't believe that a gas that doesn't reside too long in any one position suddenly warms the ground surface, the water column, the atmospheric column. Earth simply has different properties than Venus.
