Is it – or will it ever become – possible to attribute natural disasters to climate change? The question is attracting growing attention in the scientific literature, but it also deserves great attention in legal research. I remain unpersuaded that science can ever attribute a particular weather event to climate change, let alone the impacts of this event on societies, in abstraction from anything else. But climate change could sometimes be proven to have played a determinant role in creating the conditions where a natural disaster would become much more likely to occur; and this should be sufficient to attribute responsibility.
