Attribution of Weather and Climate-Related Extreme Events

Unusual or extreme weather and climate-related events are of great public concern and interest, yet there are often conflicting messages from scientists about whether such events can be linked to climate change. There is clear evidence that climate has changed as a result of human-induced greenhouse gas emissions, and that across the globe some aspects of extremes have changed as a result. But this does not imply that the probability of occurrence (or, given a fixed damage, risk) of a specific type of recently observed weather or climate event has changed significantly as a result of human influence or that it is likely to become more or less frequent in the future. Conversely, it
