This is not just due to error on part of researchers, but the politicization of science, something scientists, especially with regards to medical and climate science, are gathering together and speaking up about every single year.
Credible, dissenting scientific voices go largely unheard by the mainstream media and education. As a result, most of our beliefs and thoughts about what is happening on our planet come from programming, brainwashing and mass marketing heavy with mainstream politicized science.
Overall human consciousness has been influenced by the global elite, simply for the purposes of driving us into acceptance of the limited, and often ridiculous, solutions they pose for the problems that they create. This is why critical thinking and independent research is crucial for citizens.
