Newport Beach throws sand at a crisis fossil fuels created

By Sophie Naimi · Reporting from Paris · October 24, 2026

California cities are spending millions on temporary sand berms to fight record tides, but this reactive spending ignores the thermal expansion driven by global carbon emissions.

The Pacific Ocean is not just rising; it is expanding. As global temperatures climb, the water absorbs the heat and swells. This is basic physics, not a weather fluke. Yet, as California braces for record-breaking tides, the response is a desperate, expensive scramble for sand. We are watching a farce where municipal budgets are drained to protect beachfront real estate from a disaster funded by the fossil fuel industry. The culprits who paid for this warming are now watching from the sidelines while taxpayers pay for the sandbags.

The physics of a swelling ocean

The National Weather Service has issued a coastal flood warning for San Diego and Orange counties. It also issued advisories for Los Angeles, Ventura, Santa Barbara, and San Luis Obispo. In the Bay Area, inundation could reach 1.9 feet above ground level. This is not a standard seasonal shift. The San Francisco Chronicle reports that San Diego and Los Angeles will “more likely than not” see their highest recorded tide levels Tuesday morning.

Philip Gonsalves, a meteorologist with the National Weather Service, explains the mechanism with a simple image. He says if you heat a pot of water on a stove, the level of the water starts to rise. The same thing is happening in the ocean. This thermal expansion is bolstered by an "extraordinarily powerful El Niño" and Kelvin waves. In San Diego and Orange counties, tides could reach 7.5 to 8 feet or higher above the baseline.

This is the failure of the historical baseline. We are using past averages to predict a world that no longer exists. When the baseline is broken, the old maps become lies.

The delusion of the sand berm

In Newport Beach, the response is to throw money and dirt at the sea. The city declared a local emergency and approved a $1.5 million contract. Crews are moving sand to protect the Balboa Peninsula. At The Wedge, trucks arrive daily with the goal of delivering 2,000 cubic yards of sand by the end of the week.

Councilmember Erik Weigand argues that the city must "spend a little money today to preserve" the beach for the future. Resident Christina Grace calls the beaches "the jewel" and says they are in danger. But this is not preservation. It is a temporary stay of execution.

Long Beach is following the same path. Its dredging project will cost $11.4 million. The city will reuse dredged material to nourish Peninsula Beach. Capistrano Beach Park is also receiving sand at public cost.

We are treating the symptoms while the disease—carbon emissions—continues to burn. The Orange County Register notes that warm water expansion can make a 7-foot tide act like a 9-foot tide. No amount of hauled sand can stop the physics of a warming planet.

A collapsing coastal corridor

The cost of this delay is not just measured in sand. It is measured in the collapse of public infrastructure. Metrolink has suspended service south of the Laguna Niguel/Mission Viejo station from Monday through Friday. This cuts off the coastal route toward San Clemente and Oceanside.

Caltrans is placing barriers to protect slopes on the Pacific Coast Highway. They plan to install a fill buttress reinforced with large rocks to limit slope movement. We saw this during the North Sea flood of 1953, when a storm surge struck low-lying coastal areas not built to withstand it.

Daniel Swain, a UC climate scientist, warns that it is “likely to get worse before it gets better.” The long record shows that temporary fixes fail. We have seen this with the repeated closures of the rail corridor in San Clemente. Each time, a temporary fix is applied, and each time, the next storm washes it away. We are spending millions to maintain a baseline that the ocean has already erased.

The money for these projects comes from tideland funds and emergency accounts. This is a hidden tax on the public to protect a coastline that is being eaten by the consequences of global carbon. While Newport Beach expects tides of 8.5 feet on Tuesday, the companies that drove the warming are posting record profits. They have successfully externalized the cost of their business model onto the city budgets of California.

We must stop pretending that sand-trucks are a climate strategy. The current approach is a subsidy for beachfront property owners paid for by the public. If we continue to rely on emergency municipal outlays, these cities will face severe budget deficits. They will cut public services to pay for the privilege of fighting the tide. The only honest solution is a Climate Superfund. The fossil fuel extractors must pay for the thermal expansion they caused. Until the polluter pays for the sand, we are just rearranging the beach while the house burns.
