After years of coastal erosion, communities such as Pacifica, south of San Francisco, are already showing strain, and officials worry heavy winter storms could worsen damage to weakened cliffs and hillsides.

President Trump is escalating a fight against California's authority to set its own climate and emissions standards, challenging rules that have long made the state a national leader on environmental policy. The confrontation raises questions over whether federal power or state-level climate ambition will prevail, with regulators, automakers and other states watching closely for the outcome.

SpaceX launched a classified payload for the US Space Force from Vandenberg Space Force Base in California, then landed the Falcon 9 booster on a droneship at sea. Multiple US local news outlets carried the report. The mission's cargo and purpose remain undisclosed, consistent with the military's practice of keeping national security payloads secret.

Hurricane Polo is approaching Baja California Sur, Mexico, with landfall expected between 4 and 6 pm on Monday, September 28. Authorities have restricted movement in the state as strong winds and high surf hit the coast. Together with Tropical Storm Rachel, Polo is intensifying rainfall across Mexico's Pacific coast, and a high-surf and coastal flooding advisory has been issued for southern California. President Claudia Sheinbaum addressed the population ahead of the storm's arrival.

SpaceX launched a classified U.S. Space Force payload from California, with few details released about the mission's purpose or cargo. The secrecy surrounding the launch is drawing attention, as observers speculate about what the military is sending to space and why information is being withheld.

The Trump administration has moved to roll back federal fuel economy standards, weakening requirements that pushed automakers to build more efficient vehicles. The change is expected to lower compliance costs for carmakers while drawing criticism from environmental groups and states concerned about higher emissions and fuel consumption. The move also sets up potential conflicts with California's stricter vehicle rules and could reshape the US auto market for years to come.

A vast, slow-moving kelvin wave — an ocean phenomenon tied to the El Niño–Southern Oscillation — is reported to be heading toward the California coast, raising alarm among scientists and officials about its potential impact on weather patterns along the US West Coast. Comment is focused on what the wave could mean for extreme weather and coastal conditions in the region.

Scientists and weather watchers are tracking a vast, slow-moving Kelvin wave—a planetary-scale ocean or atmospheric pattern—that is heading toward California. The development is drawing attention because such waves can influence coastal conditions and extreme weather, and concern is mounting over what impact it could bring to the US West Coast.

California is looking to turn a potentially wet El Niño winter into an opportunity, pursuing efforts to capture stormwater from the big storms expected to hit the state. Officials want to store runoff to recharge groundwater supplies and boost reservoirs, rather than letting it flow out to sea, as drought-strained water systems seek any advantage from the pattern.

Recent reporting ranks the 10 US states with the most electric vehicle charging stations, as electric car sales continue to climb nationwide. California typically leads such rankings, followed by other large populous states, reflecting where charging infrastructure has expanded fastest. Interest comes as drivers weigh range and charging access against rising EV adoption.

The Trump administration is moving to reduce fuel economy standards for vehicles in the United States. The reported rollback would loosen requirements on carmakers to improve average fuel efficiency, a policy likely to draw opposition from environmental groups and states such as California that have backed stricter rules.
