Bay Area Climate Change

  1. 1. Climate Change and The Bay Area Joint Policy Committee Climate Change Workshops February 16 th and 23 rd , 2007
  2. 2. Climate Summit: Key Messages <ul><li>Climate change is a serious problem globally and locally </li></ul><ul><li>Our actions will affect how much the climate ultimately changes </li></ul><ul><li>The Bay Area has been a leader and will continue to be a leader in climate protection </li></ul><ul><li>Working together, the Bay Area will be a model for California, the nation and the world. </li></ul>
  3. 3. 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

  14. 14. Strategies: Real Innovation Required <ul><li>Targets are aggressive </li></ul><ul><li>No silver bullet </li></ul><ul><li>Will require multiple changes, some fundamental </li></ul><ul><li>Business as usual will not be good enough </li></ul><ul><li>Some strategies will be relatively painless </li></ul><ul><li>Many will be difficult, costly, and contentious </li></ul><ul><li>Either way, it will be a very different world </li></ul><ul><li>Some impacts are inevitable </li></ul><ul><li>It will be tough but doable </li></ul>

  17. 17. Strategies: Smart Growth & Transportation <ul><li>Highly beneficial, and necessary </li></ul><ul><li>But not sufficient—at least in the short term </li></ul><ul><li>Big difference in the long term </li></ul><ul><li>But we will need more to meet 2020 target </li></ul><ul><li>1% annual growth </li></ul><ul><li>In any year, 99% of development is a given </li></ul>
  18. 18. Strategies: Smart Growth & Electricity <ul><li>Temperature gradient: as much as a degree per mile </li></ul><ul><li>Synergy: reduced energy for cooling + reduced energy for transportation </li></ul>
