Climate Change Impact and Adaptation Assessment Projected warming (ºF) by NASA center, 2080s minus 1980s averaged across 16 GCMs under the A1B emissions scenario Cynthia Rosenzweig NASA Goddard Institute for Space Studies Environment, Energy Security, and Sustainability Symposium New Orleans, LA, May 10, 2011
Responding to Climate Change Mitigation involves actions that decrease the atmospheric concentration of greenhouse gases (GHGs). This can be done by reducing GHG emissions and by enhancing the storage of carbon on the earth. Adaptation involves actions that reduce the effects of climate change or enhance the benefits. Mitigation & adaptation can be interactive
Approach to Adaptation Climate Risk Management Climate risk management is designed for decisionmaking under uncertainty. Advantages of climate risk management include: - Use of formalized methods to manage uncertainty - Stakeholder involvement - Use of methods for evaluating policy options without being policy-prescriptive - Integration of different disciplinary approaches - Mainstreaming of climate-change concerns into the broader decision-making context Intergovernmental Panel on Climate Change, 2007

Sustainability Plan for NYC The plan features 10 goals Create more homes for almost a million more New Yorkers, while making housing affordable and sustainable housing Ensure that all New York live within a 10-minute walk of a park Clean up all contaminated land Open 90% of waterways for recreation by reducing water pollution and natural area preservation Develop critical back-up systems for water network Improve travel times by adding transit capacity Reach a full state of good repair on roads, subways and rails Provide cleaner and more reliable power Achieve the cleanest air of any big city in America Reduce global warming emissions by more than 30% PlaNYC is New York City s plan for a sustainable future (April, 2007) All linked to climate change mitigation and adaptation Available online at: http://www.nyc.gov/planyc
Establish Guiding Principles Flexible Adaptation Pathways Key elements to achieve Flexible Adaptation Pathways are a guiding framework, stakeholder engagement, expert knowledge providers, recurring assessment process, Action Plans by decision-makers, and vertically/horizontally integrated projects with ongoing evaluation Source: NPCC, 2010

Design Adaptation Process 1. Identify current and future climate hazards 2. Conduct inventory of infrastructure and assets and begin to identify vulnerabilities 3. Characterize risk 4. Develop initial list of strategies 5. Prioritize strategies 6. Prepare and implement Adaptation Plans 7. Monitor and reassess New York City Panel on Climate Change

Characterize Risk Red Orange Yellow risks for which adaptation strategies should be developed risks for which adaptation strategies may need to be developed or for which further information is needed risks for which impacts should be monitored but which may not need actions at this time Source: Columbia University Center for Climate Systems Research To determine risk of climate change on infrastructure 1. Probability of a climate change hazard 2. Likelihood of that hazard causing an impact 3. Magnitude of consequence, should that impact occur New York City Panel on Climate Change
Develop and Prioritize Adaptation Strategies Potential Strategy Prioritization Categories - Cost - Feasibility - Timing of Implementation - Efficacy - Resiliency Rating - Co-benefits New York City Panel on Climate Change
Framing Adaptation Reduce the level of physical, social, or economic impact of climate change and variability Take advantage of new opportunities emerging from climate change Type Management/operations Infrastructure physical components of each sector Policy Administrative Group Private vs. public organizations Local/municipal, county, state, national Level of Effort Incremental action Large-scale shifts Timing Short term <5 yrs; medium term 5-15 yrs; long term >15 years Abrupt Changes - tipping points/policy triggers Scale Wide-spread, clustered, isolated/unique
