Join the Human Wave – 350.org Day of Action: Connect the Dots on Climate Change

05/05/2012 @ 10:30 am - 12:30 pm

Part of 350.org’s international day of action. Join us in Mission Beach to highlight coastal flooding, one of the major projected impacts for San Diego County.

San Diegans will form a human wave in Mission Beach on Saturday, May 5th to connect the dots between extreme weather and climate change. The San Diego event will be one of thousands of events occurring around the country and the world with communities everywhere connecting the dots between the extreme weather already wreaking havoc around the world – including flooding, fires, hurricanes, and droughts – and climate change.

Here in San Diego, rising sea levels combined with more powerful storms will mean regular flooding of our coastal communities, causing irreparable damage to our beaches, coastal homes, businesses and recreational facilities, tourist industry, and our unique plants and wildlife. By 2050 it is projected that most Mission Beach streets will flood at high tide and storm surges will inundate of homes, streets and businesses significantly impacting property values. More sewage and hazardous wastes will reach our beaches and bay, contaminating beaches, parks, and flooded residential and commercial areas, leading to additional health risks and economic impacts.

Sea levels rose in our area by about 7 inches in the 20th century and another 12-18 inches of sea level rise is expected by 2050. This will result in serious flooding in low-lying areas with permanent loss of current sandy beach and increasingly frequent intrusion into near-shore streets, recreational areas, ecosystems and wetlands along San Diego County’s roughly 70 miles of coastline. A recent estimate of the cost of mitigating sea level rise in San Diego County are in the $25-50 million range for sea wall construction, beach nourishment, halting new building in heavily disturbed areas, etc., along with additional annual costs.

We’ll also have a few speakers and a special climate song performed by San Diego’s own Occupellas Chorus. We encourage participants to carpool or to take public transit if possible. A list of public transit options from different areas is here.

Mission Beach: Tidal fluctuations alone (purple) appear to inundate portions of sandy beach and streets from bayside flooding. Adding run-up from moderately common wave events (blue) floods majority of sandy beach, streets and parts of Mission Beach Park. Moderately rare wave events (green) appear to breach seawall and inundate streets and sidewalks. Very rare wave events (red) flood sandy beach, surface streets and heavily-used boardwalk in Mission Beach.
