How do you know there are problems? Have you looked into the data and methodology yourself? Do you have the requisite education and experience to understand the methodology to identify potential issues? Do you have the data analysis experience to examine large sets of data, and are you able to determine which data are correct and which are not? Do you have a team of researchers who are able to peer review your findings? Did you then submit your findings to scientific journals for other scientists to review? Have you received feedback from other researchers, addressed their concerns, and determined that your findings and data are still relevant and correct? If so, please share your research, I would very much be interested in reading it. I would also be interested in hearing about your academic and research experience, as well as that of your co-authors, so I can apply the proper context to your findings.
It's worth noting that even issues with fairly broad consensus, such as the link between smoking and lung cancer, still have detractors and people who call the consensus into question. In this specific example, the detractors are mostly tobacco companies, but still, the point remain: anyone anywhere can call research into question. That doesn't mean the scientific process and findings aren't accurate, it just means that someone has taken issue with the process or the findings. If one was to discount the importance of consensus surrounding smoking causing lung cancer, they would be claiming that every single research team that has done clinical and scientific research around this issue has serious problems with their approach, data, methodology or all of the above. This is highly unlikely. The academic and scientific community has many layers of review in place. It's not impossible for junk research to be released, but it's almost impossible for it to gain consensus.
Interesting side note, the science and data behind climate change and man's influence in it are
as agreed upon as the science and findings that show smoking causing lung cancer.
