Yes, of course you can maintain your job. Witness Dr. Judith Curry of Georgia Tech. She was very critical of the science around climate change and continued to hold a prestigious chair for 10 years until she retired to do consulting for energy companies.
The scientific community has a proud tradition of scientists who question conventional wisdom. As long as they make good arguments and can prove their theories then they are highly lauded.
If you think that the scientific consensus on Climate is wrong then you either believe:
1) You know more than the scientific community
2) The scientific community is engaged in a global scientific conspiracy.
Either belief makes you a loon. And I won't discuss science with a crazy person.
