What is the link between water and climate change?
The IPCC Fifth Assessment Report (AR5) highlights how water is an essential crosscutting theme when addressing climate change. It provides new scientific evidence and a major advance about the likelihood of “a detectable human influence on the global water cycle since 1960”. With links to selected research publications, this Key Issues Guide provides a brief snapshot of three issues relevant to the state of uncertainties around climate change and water resources: complex science, development impacts and the trade-offs between water-energy-food security.
