Metrics for “Dangerous” Change Extermination of Animal & Plant Species 1.Extinction of Polar and Alpine Species 2. Unsustainable Migration Rates Ice Sheet Disintegration: Global Sea Level 1. Long-Term Change from Paleoclimate Data 2. Ice Sheet Response Time Regional Climate Disruptions 1. Increase of Extreme Events 2. Shifting Zones/Freshwater Shortages Taken from James Hansen’s presentation: Climate Threat to the Planet. The Path from Science to Action. Trinity International University June 5 2009
Assessment of Target CO2 (Hansen et al 2009) • PhenomenonTarget CO2 (ppm) • 1. Arctic Sea Ice 300-325 • 2. Ice Sheets/Sea Level 300-350 • 3. Shifting Climatic Zones 300-350 • 4 Alpine Water Supplies 300-350 • 5. Ocean Acidification 300-350 • Initialtarget CO2 <350 ppm* *assumes CH4, O3, Black Soot decrease Taken from James Hansen’s presentation: Climate Threat to the Planet. The Path from Science to Action. Trinity International University June 5 2009
Key actions for getting back to 350ppm 1. Phase Out Coal CO2 Emissions - by 2025/2030 developed/developing countries 2. Rising Carbon Price - discourages unconventional fossil fuels & extraction of every last drop of oil (Arctic, etc.) 3. Soil & Biosphere CO2 Sequestration - improved farming & forestry practices 4. Reduce non-CO2 Forcings - reduce CH4, O3, trace gases, black soot
In summary: • Human driven climate change is real and the danger is far greater than most people are aware. • It’s imperative that we restore Earth’s energy imbalance (i.e. get back to <350ppm CO2.) with all urgency. • We need to understand & act on the developing threat & response imperatives. • We should be redoubling efforts to ensure the current destruction of natural systems is halted. These are key to our survival. • We need to be planning for the now unavoidableimpacts of climate change. • We have precious little timeto avert runaway climate change.

Zoo community focus actions: • Keep on top of the emerging threat and response information and the wider environmental/climate community. • Take up and disseminate the WAZA position statement and support materials • Consider decision maker communication initiatives (as we did for COP-15) • Increase pubic engagement (exhibits, Websites, media, talks/symposia etc) • Realise potential of our zoo sites for research. • Need to agree improvements to current threat evaluation process. • Highlight Zoo focus species (CP and ICP programmes etc) • Need to increase specialist collaborations (e.g. Hadley, NASA) • Fully utilise the international WAZA community network. • Need to be flexible and responsive to emerging developments (eg phytoplankton decline) and react accordingly.
