Bay Area Climate Change Bay Area Climate Change Presentation Transcript

  • Climate Change and The Bay Area Joint Policy Committee Climate Change Workshops February 16 th and 23 rd , 2007
  • Climate Summit: Key Messages
    • Climate change is a serious problem globally and locally
    • Our actions will affect how much the climate ultimately changes
    • The Bay Area has been a leader and will continue to be a leader in climate protection
    • Working together, the Bay Area will be a model for California, the nation and the world.
  • Local Consequences: By the End of the Century Source: California Climate Action Team … or Earlier NA 55% 10-35% Increase in large fire risk 20% 11% 3-6% Increase in electricity demand 3-4X 2-2.5X 1-2X Heatwave days 22-30” 14-22” 6-14” Sea level rise 90% 70-80% 30-60% Snow pack loss 8.0-10.4 ° 5.5-7.9 ° 3.0-5.4 ° Temperature rise Higher (970 ppm) Medium-High (830 ppm) Lower (550 ppm) Emission Scenario

  • Contributors: CO 2 Emissions per Capita Sources: USEIA, CA Climate Action Team, BAAQMD
  • Contributors: California GHGs Source: California Climate Action Team
  • State Targets: 2020 Target 2010 Target Source: California Climate Action Team
  • Strategies: The State’s Initial Top Six California Climate Action Team
  • Strategies: Beyond Emission Standards Source: MTC Source: MTC
  • Strategies: Real Innovation Required
    • Targets are aggressive
    • No silver bullet
    • Will require multiple changes, some fundamental
    • Business as usual will not be good enough
    • Some strategies will be relatively painless
    • Many will be difficult, costly, and contentious
    • Either way, it will be a very different world
    • Some impacts are inevitable
    • It will be tough but doable
  • Backup
  • Local Consequences: Wildfire Frequency Source: California Climate Change Center
  • Strategies: Smart Growth & Transportation
    • Highly beneficial, and necessary
    • But not sufficient—at least in the short term
    • Big difference in the long term
    • But we will need more to meet 2020 target
    • 1% annual growth
    • In any year, 99% of development is a given
  • Strategies: Smart Growth & Electricity
    • Temperature gradient: as much as a degree per mile
    • Synergy: reduced energy for cooling + reduced energy for transportation
