How should we communicate uncertainty in climate-attribution claims?

   The honest framing is that attribution shifts probabilities, not causes. A specific heatwave is rarely "caused" by climate change; it is made N times more likely. Most public-facing communication still elides this distinction, and the result is whiplash when an event happens that would have happened without warming.

   From the editorial side: the probability framing reads as evasion to non-specialist audiences. We need a vocabulary that conveys "strongly causal in expectation, uncertain in any single instance" without sounding hedged. I do not think we have one yet.

   The probability framing also lets us be honest about events where the attribution is weaker. Not every extreme is a clear signal — some are. Conflating them in public communication erodes credibility for the strong attribution claims later.
