Baltimore is latest US city to file lawsuit against Big Oil

Baltimore on Friday become the latest U.S. city to try and hold the world's biggest oil companies financially responsible for global warming, asserting it faces massive costs to effectively protect its residents, businesses and infrastructure from the escalating impacts of climate change. The litigation by Baltimore, wrapped around a cove of the Chesapeake Bay, comes as skeptical judges elsewhere have been throwing out headline-generating complaints brought by other cities that sought to force big oil companies to pay for climate change adaptation. On Thursday, a U.S. judge rejected New York City's lawsuit targeting oil companies, saying the issue must be addressed by Congress and the executive branch.
