The Drought in California Is So Bad the Ground Is Literally Sinking
Vast stretches of California's Central Valley are sinking faster than in the past as the state continues to pump out massive amounts of groundwater during its epic drought, NASA said in a report released Wednesday. The Golden State has been forced to rely more and more on groundwater as it grapples with a four-year drought, record low snowpack and reservoirs that are running dangerously low.

The report found that some places are losing nearly two inches per month.
“Because of increased pumping, groundwater levels are reaching record lows—up to 100 feet lower than previous records,” said Department of Water Resources Director Mark Cowin. “As extensive groundwater pumping continues, the land is sinking more rapidly and this puts nearby infrastructure at greater risk of costly damage.”
Sinking land, or subsidence, has been a problem in California's Central Valley for decades as the state has had to rely on increasing amounts of groundwater. But now NASA data, which the agency obtained by comparing satellite images of the Earth’s surface over time, reveals the problem is the worst its ever been.

Land near Corcoran in the Tulare basin sank 13 inches in just eight months—about 1.6 inches per month. One area in the Sacramento Valley was sinking approximately half-an-inch per month, faster than previous measurements. NASA also found areas near the California Aqueduct sank up to 12.5 inches, with eight inches of that occurring in just four months of 2014.
The increased subsidence rates have the potential to damage local, state and federal infrastructure, including aqueducts, bridges, roads and flood control structures. Long-term subsidence has already destroyed thousands of public and private groundwater well casings in the San Joaquin Valley. Over time, subsidence can permanently reduce the underground aquifer’s water storage capacity.
In response to the findings, Gov. Brown's Drought Task Force has pledged to help local communities reduce subsidence, protect infrastructure and to better manage sustainable groundwater supplies. The Department of Water Resources will also launch a $10 million program to help communities with groundwater-stressed basins, or strengthen local ordinances or conservation plans.
And Californians aren't the only ones with that sinking feeling. Last week, a study showed parts of southern Arizona are sinking too. The U.S. Geological Survey has identified more than 17,000 square miles (an area the size of New Hampshire and Vermont combined) of land subsidence in 45 states.

Glyphosate, the main ingredient in Monsanto's widely used herbicide Roundup, will be added July 7 to California's list of chemicals known to the state to cause cancer, according to a Reuters report Tuesday. This news comes after the company's unsuccessful attempt to block the listing in trial court and requests for stay were denied by a state appellate court and California's Supreme Court.
California's Office of Environmental Health Hazard Assessment (OEHHA) announced the designation on Monday under the Safe Drinking Water and Toxic Enforcement Act of 1986, or Proposition 65.
Canadian government officials and marine biologists are investigating the mysterious deaths of six North American right whales. The endangered animals all turned up dead between June 6 and June 23 in the Gulf of St. Lawrence, off Canada's southeastern coast.
North Atlantic right whales are the rarest of all large whale species and among the rarest of all marine mammal species, with only about 450 right whales in the North Atlantic.

Sequoiadendron giganteum. That's the scientific name for the giant sequoia: the mammoth trees found in California's Sierra Nevada that are the largest organisms on Earth, and among the longest-lived. Biologists estimate that about half of all sequoias live in Giant Sequoia National Monument, a 328,000-acre preserve in the Southern Sierra Nevada established by President Clinton in 2000.
Now that national monument is in jeopardy.
