Abstract
The evidence most of us have for our beliefs on global climate change, the extent of human contribution to it, and appropriate anticipatory and mitigating actions turns crucially on epistemic trust. We extend trust or distrust to many varied others: scientists performing original research, intergovernmental agencies and those reviewing research, think tanks offering critique and advocating skepticism, journalists transmitting and interpreting claims, even social systems of modern science such as peer-reviewed publication and grant allocation. Our personal experiences and assessments of evidential indicators themselves may be buttressed significantly by trust, not just in.
