Transcript

  • 1. Nicole Russell Ph.D. Student Department of Earth and Planetary Sciences Gary Griggs Director Institute of Marine Sciences University of California Santa Cruz
  • 2.
    • Coastal counties: 24% of CA’s area but home to 80% of Californians
    • ~35 million visitors/yr and $23 billion/yr
    Malibu, CA
  • 3.
    • OPC has adopted 10-17 inch rise by 2050 & 40-55 inch rise by 2100
  • 4.
    • Current global rate: ~2-3 mm/yr
    • Rate may be increasing
    • Besides, local rates matter most
  • 5. Alaska
    • 4.24 ft/100 yrs
    • (-12.92 mm/yr)
    noaa.gov Louisiana + 3.03 ft/100 yrs (+ 9.24 mm/yr)
  • 6. California + 0.66 ft/100 yrs (+ 2.01 mm/yr)
  • 7.  
  • 8.
    • Inundation of low-lying areas
    Main Beach, Santa Cruz 2008 Lynne Harden
  • 9.
    • Passive erosion
    Projection: 3 foot sea level rise by 2100
  • 10.
    • Inundation: we’ve seen it before…
    Mission Beach, San Diego Winter 1988
  • 11. San Francisco Airport with 16 inches of sea level rise
  • 12.
    • Increased cliff erosion
    Antigua Apartments Depot Hill (www.Californiacoastllne.org)
  • 13. Pacifica 2010
  • 14.
    • Storm damage
    Pacifica 1998
  • 15.
    • Santa Cruz Boardwalk, 1926 El Niño
  • 16.
    • Boardwalk during 1997-98 El Ni ñ o
  • 17.
    • Every community has a unique geographic setting and people
    • Planning officials must understand local vulnerabilities in order to form appropriate adaptation strategies
      • Well-documented disconnect between science and practice
  • 18.
    • Improve transfer of relevant information from scientists to decision-makers
    • i.e. local SLR  flood levels  new flood hazard maps;
    • coastal cliff retreat  setbacks
    Plan Santa Barbara Draft Environmental Impact Report
  • 19.
    • Perform SLR vulnerability assessments for two specific coastal communities in order to identify:
      • Range of hazards
      • Types of information needed for assessing vulnerability
      • Range of available adaptation approaches
      • Recommended adaptation strategies
  • 20.
    • Create a guide for developing local mitigation plans
      • Vulnerability assessments
        • Risk-based
    Santa Cruz City Climate Adaptation Plan
  • 21.
    • SLR adaptation plans for Santa Cruz and Santa Barbara, CA
    • Guide available to all of California’s coastal communities
    Santa Barbara County, CA
  • 22.
    • California Energy Commission (PIER Program)
    • Cities of Santa Cruz and Santa Barbara, CA
  • 23.
