Water Availability Has Changed, and Humans Are to Blame


A new study, realized with the contribution of the CMCC Foundation, demonstrates for the first time that human-induced climate change has influenced water availability on land in the driest months of the year, over the last century.

Changes in the water cycle have important impacts on ecosystems and human activities. In the context of the current and expected temperature rise due to global warming, it is extremely important to understand the origin and extent of these changes.

A recent study published in the journal Nature Geosciences analyses the changes in global average water availability on land – defined by the difference between precipitation and evapotranspiration – eliminating any remaining uncertainties about human responsibility for variations in the hydrological cycle observed during the dry-season throughout the last century.

The research, realized with the contribution of the CMCC Foundation – Euro-Mediterranean Center on Climate Change, is entitled “Observed changes in dry-season water availability attributed to human-induced climate change” and is made up of two phases.
