   gcis:findingStatement "Detectable changes in some classes of flood frequency have occurred in parts of the United States and are a mix of increases and decreases. Extreme precipitation, one of the controlling factors in flood statistics, is observed to have generally increased and is projected to continue to do so across the United States in a warming atmosphere. However, formal attribution approaches have not established a significant connection of increased riverine flooding to human-induced climate change, and the timing of any emergence of a future detectible anthropogenic change in flooding is unclear. (<em>Medium confidence</em>)"^^xsd:string;

## Properties of the finding:
   gcis:findingProcess "The key finding is a relatively weak statement reflecting the lack of definitive detection and attribution of anthropogenic changes in U.S. flooding intensity, duration, and frequency."^^xsd:string;
   
   gcis:descriptionOfEvidenceBase "Observed changes are a mix of increases and decreases and are documented by Walsh et al. and other studies cited in the text. No attribution statements have been made."^^xsd:string;
   
   gcis:assessmentOfConfidenceBasedOnEvidence "Confidence is limited to <em>medium</em> due to both the lack of an attributable change in observed flooding to date and the complicated multivariate nature of flooding. However, confidence is <em>high</em> in the projections of increased future extreme precipitation, the principal driver (among several) of many floods. It is unclear when an observed long-term increase in U.S. riverine flooding will be attributed to anthropogenic climate change. Hence, confidence is <em>medium</em> in this part of the key message at this time."^^xsd:string;
   
   gcis:newInformationAndRemainingUncertainties "Floods are highly variable both in space and time. The multivariate nature of floods complicates detection and attribution."^^xsd:string;
