The Drought in California Is So Bad the Ground Is Literally Sinking

Climate

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.

NASA says:

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.

The beauty products we put on our skin can have important consequences for our health. Just this March, the U.S. Food and Drug Administration (FDA) warned that some Claire's cosmetics had tested positive for asbestos. But the FDA could only issue a warning, not a recall, because current law does not empower the agency to do so.

Michelle Pfeiffer wants to change that.

The actress and Environmental Working Group (EWG) board member was spotted on Capitol Hill Thursday lobbying lawmakers on behalf of a bill that would increase oversight of the cosmetics industry, The Washington Post reported.

The climate crisis is a major concern for American voters with nearly 40 percent reporting the issue will help determine how they cast their ballots in the upcoming 2020 presidential election, according to a report compiled by the Yale Program on Climate Change Communication.

Of more than 1,000 registered voters surveyed on global warming, climate and energy policies, as well as personal and collective action, 38 percent said that a candidate's position on climate change is "very important" when it comes to determining who will win their vote. Overall, democratic candidates are under more pressure to provide green solutions as part of their campaign promises with 64 percent of Democrat voters saying they prioritize the issue compared with just 34 percent of Independents and 12 percent of Republicans.

President Donald Trump has agreed to sign a $19.1 billion disaster relief bill that will help Americans still recovering from the flooding, hurricanes and wildfires that have devastated parts of the country in the past two years. Senate Republicans said they struck a deal with the president to approve the measure, despite the fact that it did not include the funding he wanted for the U.S.-Mexican border, CNN reported.

"The U.S. Senate has just approved a 19 Billion Dollar Disaster Relief Bill, with my total approval. Great!" the president tweeted Thursday.
