The updated and more aggressive climate action plan adopted by the city of San Diego this month is committing to creating 700 acres of marshland across the city, more than triple the 220 acres of new marshland Mayor Todd Gloria had previously promised in northeastern Mission Bay.
The Union Tribune says the city's revised climate action plan prioritizes new marsh areas because they serve the dual purpose of removing greenhouse gases like carbon dioxide from the air and fighting sea-level rise by acting as a coastal sponge.
In addition to Mission Bay, other possible locations for new marshland include the Los Peñasquitos Lagoon in the Torrey Pines Natural Reserve, Tecolote Creek, Cudahy Creek and parts of Fiesta Island.
Other elements of the revised plan include banning natural gas in new homes and getting more people to commute by public transit and bicycles.
