WGI  concludes with high confidence that without large-scale reduction in GHG emissions, global warming is projected to cause substantial changes in the water cycle at both global and regional scales. However, WGI also noted large uncertainties in many aspects of regional water cycle projections by climate models. Water cycle variability and extremes are projected to increase faster than average changes in most regions of the world and under all emission scenarios . The concept of 'wetter regions get wetter, drier regions get drier' from AR5  is assessed by AR6 WGI  as too simplistic. WGI  further concludes that heavy precipitation will generally become more frequent and more intense with additional global warming.
