A note about identifying climate change impacts

Many events are linked to climate change by virtue of fitting a long-term trend. For example, the record-breaking “once in one thousand years” rains that drove the recent Nashville flood is part of the long-term trend of increasing heavy precipitation events in the Southeastern United States that has been fully documented and firmly attributed to climate change. While one cannot say with certainly that event was "caused" by climate change, one can and should say it is linked to climate change.
