Rainfall over the Andes in Bolivia and Peru could decrease dramatically in the next century. Water utilities in California are raising rates as the drought continues. Reporters at Wired have asked an age-old question about that glass of water next to the bed.

“The persistence of this drought has begun to outstrip the tools utilities typically use to manage the state’s hydrological cycles.” — Kathryn Masterson, senior director at rating agency Fitch, which recently polled California water utilities about their plans to raise rates. (Reuters)

78 percent – Proportion of polled California water utilities saying that rates would increase next year or have already increased.

Science, Studies, And Reports

Rainfall in the central Andes of Bolivia and Peru could decline by up to 30 percent by 2100, according to a new study by researchers from South America and the University of Zurich. Greenhouse gas emissions are changing wind patterns and keeping more humid air from reaching the mountains and causing precipitation. Models suggest that between 2017 and 2100, the likelihood of dry years will be four times what it was in the pre-industrial era. Thomson Reuters Foundation

Potential reasons include changes in temperature and composition of dissolved gases in the water, or, if the glass is sitting out for days and days, microbial growth. Wired
