Beschreibungen/Notizen

• The last 10 years have featured intense climate-hydrological extremes in the Amazon region: 2005, 2009, 2010, 2012–2013, and 2014–2015 leading to great impacts, such as large-scale droughts and floods, some of them being classified as ‘once-in-a-century’ events. Historical records show previous droughts in 1926, 1964, 1980, 1983, and 1998 and floods in 1953, 1988, and 1989. These events have been linked to natural climate variability and they impact on natural and human systems. Main cities in the Amazon region were flooded or were isolated by the extremely low river levels during the droughts. Model projections suggest that such extremes could be more frequent/intense in the future and that human activities, mainly in the form of land use change leading to increases in greenhouse gas concentration, may aggravate such extremes and make the impacts on the populations stronger. In this chapter, we review climate-hydrological extremes in a historical context, assessing observed trends, projected climate change scenarios, and the likelihood and uncertainties inherent to those scenarios.
