At least five California municipalities are suing five major oil companies, claiming in public nuisance lawsuits that the firms should pay for the infrastructure costs associated with rising sea levels due to climate change.

The latest suits announced Wednesday by Oakland and San Francisco name BP, Chevron, ConocoPhillips, ExxonMobil, and Royal Dutch Shell. The cities claim the oil companies knew of the dangers of fossil-fuel-driven climate change but kept mum. The cities claim that global warming, which they say has melted ice sheets and heated sea water, has contributed to rising seas by about eight inches in California over the past decade. They say it could rise 10 feet by the year 2100.

“The bill has come due,” San Francisco City Attorney Dennis Herrera said. “It’s time for these companies to take responsibility.”
