Angelenos surely hope that the climate change induced scenario described by MacDonald isn't the bookending sequal to the story of the founding of Los Angeles featured in the film Chinatown.

According to MacDonald, "Not only do scientists predict that rising sea levels will increase the likelihood of coastal flooding there, but also that rising temperatures will threaten the snow pack in the Sierra Nevada mountains, which provides about a third of the drinking water used by the L.A. Department of Water and Power, the nation's largest municipal utility."

Luckily, city officials aren't standing pat. MacDonald reports on the efforts of the mayor's office and the city's water department to plan mitigation measures for these future problems.
