Maybe in some degenerate form of consensus, like consensus on raw observations. If one person sees a rise in temperature during a reaction, someone else can say "nuh-uh, la la la".
Other forms of scientific disagreement happen, but those disagreements imply different predictions, and can be resolved with more experiments.
Science is a process that bootstraps broad agreements (scientific laws) from very tiny agreements (observations). The fact that a broad agreement (consensus) exists carries no weight if one lone wacky scientist can show reproducible observations that contradict it.
