Approximately 117 million more people could face water shortages if global temperatures increase 2 degrees Celsius above pre-industrial levels compared to a 1.5-degree Celsius increase in temperatures, a new study suggests.
The world’s water cycle, including evaporation and precipitation, is expected to intensify with global warming, according to the study. This could affect the distribution of freshwater and constrain the global water supply, which poses risks to national food security, economic prosperity and societal well-being.
In a new study, published in Geophysical Research Letters, a journal of the American Geophysical Union, researchers examined how global freshwater could change under 1.5- and 2-degree Celsius increases in temperatures, targets set forth in the Paris Agreement.
