AR6 WGI  concluded that GHG forcing has driven increased contrasts in precipitation amounts between wet and dry seasons and weather regimes over tropical land areas , with a detectable precipitation increase in the northern high latitudes . GHG forcing has also contributed to drying in dry summer climates, including the Mediterranean, southwestern Australia, southwestern South America, South Africa and western North America  . AR6 WGI  also concluded that the frequency and intensity of heavy precipitation events have likely increased at the global scale over most land regions with good observational coverage. Heavy precipitation has likely increased on the continental scale over North America, Europe and Asia. Regional increases in heavy precipitation frequency and  intensity have been observed with at least medium confidence for nearly half of the AR6 WGI climatic regions . Human influence, in particular GHG emissions, is likely the main driver of the observed global-scale intensification of heavy precipitation in land regions
