Professionals have an ethical obligation to bear witness to climate change. They should report, warn, criticize, and lobby to bring attention to the existential threat that climate change poses. But they also have an obligation to respect the knowledge that is the basis of their authority to witness. Witnessing carries risks to this professional authority. Witnessing professionals should avoid letting bias distort their advocacy, simplifying their statements excessively, overplaying the consensus in the field, neglecting their own conflicts of interest, and claiming authority beyond their areas of expertise. To witness ethically, the professional should advocate responsibly.

见证专业人士的职业道德

专业人士有道德义务见证气候变化。他们应该报告，警告，批评和游说，以引起人们对气候变化所构成的生存威胁的关注。但是他们也有义务尊重作为见证人权威的基础的知识。见证会给这个专业机构带来风险。见证专业人士应避免偏见扭曲他们的主张，过分简化他们的陈述，夸大该领域的共识，忽视他们自己的利益冲突，以及在他们的专业领域之外主张权力。为了在道德上作见证，专业人员应负责任地倡导。
