NASA study finds major shifts in water supplies worldwide

Using measurements from Earth-observing satellites, NASA scientists have tracked changes in water supplies worldwide and they’ve found that in many places humans are dramatically altering the global water map. … Their findings in a new study reveal that of the 34 “hotspots” of water change in places from California to China, the trends in about two-thirds of those areas may be linked to climate change or human activities, such as excessive groundwater pumping in farming regions.

Facing climate and water pressures, farmers return to age-old practice

This spring in California several orchards around Solano and nearby counties sported a new look: lush carpets of mixed grasses growing as tall as 3ft beneath the trees’ bare branches. By summer the scene will change as farmers grow and harvest their nut crops, but the work of the grasses will continue unseen. Cover cropping, an agricultural technique as old as dirt, is taking root in California.

Q&A: Impact of a warming climate on the Sierra Nevada and California’s water

Imagine a California where springtime temperatures are 7F warmer than they are today, where snowmelt runoff comes 50 days earlier and the average snowpack is just 36 percent of the 1981–2000 average. That may be the reality by the end of the century if we don’t curb greenhouse gas emissions, say researchers from the University of California, Los Angeles.
