Isn't the null hypothesis that there is nothing specific to attribute the rain? The person I responded to said that attributing this anomalous weather event to climate change was no different than claims that a cool summer disprove climate change. My claim is that attribution of anomalous weather events to climate change have a higher probability of being true than claims that a cool summer disproves climate change. Neither claim is provable but one is more likely to be true than the other. The claims are different in terms of probability of being true.
