There is high confidence that the frequency and magnitude of river floods have changed in the past several decades in some regions mentioned below  with impacts across human and natural systems . A global flood database based on in situ measurement and satellite remote-sensing during 1985-2015 show that floods have increased 4-fold and 2.5-fold in the tropics and northern mid-latitudes, respectively . Estimates of flood exposure using satellite-derived inundation area and high-resolution population data showed a 20-24% increase during 2000-2018 . Analyses of in situ streamflow measurement showed both increases and decreases in the frequency of river floods for 1960-2010 in Europe  and the USA , an overall increase in China, Brazil and Australia  but decrease in some areas in the Mediterranean  and southern Australia . Warming in the last 40-60 years has led to a 1-10-d earlier per decade spring flood occurrence depending on the location   .
