Science is not a cold body of facts, but an organized system of inquiry, discovery, evaluation and learning. Science not only welcomes the correction of errors, its key attribute is that it is self-correcting over time. As new research arises, old hypotheses gain or lose support. While this process never stops, generally accepted conclusions do accumulate, based on the overwhelming weight of evidence. The fact and threat of anthropogenic climate change are clearly among those conclusions.
