Uncertainties In Climate Science Are Dominated By

Climate scientists have become entangled in an acrimonious political debate that has polarized the scientific community and has resulted in political attacks on scientists on both sides of the debate. A scientist’s ‘side’ is often defined by factors that are exogenous to the actual scientific debate.
