  • So who cares? Here are a few examples of the impacts of climate change on our lives. Details: Since 1900 significant increases in precipitation in n & s america, northern europe, north and central asia. Decline in Sahel, mediterranean, south africa and south asia Photo is downtown Annapolis Sept 2003 after Hurricane Isabel
  • By 2100, Maryland may experience relative sea-level rise of 2.7 ft under lower-emission scenarios or 3.4 feet under higher-emission scenarios. This is a LIDAR based image that depicts Maryland’s vulnerable low lying lands (not a sea-level rise model).

    • Adaptation
    • Adjustment in natural or human systems in response to actual or expected climatic stimuli or their effects, which moderates harm or exploits beneficial opportunities.

  • 6. Definitions
    • Vulnerability
    • The degree to which a system is susceptible to or unable to cope with adverse effects of climate change.
    • Vulnerability is a function of the character, magnitude, and rate of climate change and variation to which a system is exposed, its sensitivity, and its adaptive capacity .
    • Adaptive Capacity
    • Ability of a system to adjust to climate change, to reduce potential damages, take advantage of opportunities, and cope with consequences.
    (Source: IPCC AR4 WGII, 2007)
    • Critical Thresholds
    • The point in a system at which sudden or rapid change occurs.
    • Management
    • Ecological
    • Physical

  • 9. Vision for the Future: Protect Maryland’s People, Property, Natural Resources, and Public Investments Promote programs and policies aimed at the avoidance and/or reduction of impact to the existing-built environment, as well as to future growth and development in vulnerable coastal areas Shift to sustainable economies and investments; and, avoid assumption of the financial risk of development and redevelopment in highly hazardous coastal areas Enhance preparedness and planning efforts to protect human health, safety and welfare Protect and restore Maryland’s natural shoreline and its resources, including its tidal wetlands and marshes, vegetated buffers, and Bay Islands, that inherently shield Maryland’s shoreline and interior
  • 10. Adaptive Capacity Planning Puzzle
  • 11. Retain and expand forests, wetlands, and beaches to protect us from coastal flooding
    • New Criteria for Priority Protection Areas
    • Enhanced Forest and Wetland Protection
    • Sustainable Shorelines and Buffer Area Management Practices
  • 12. Climate Change Adaptation Policy: Recent Actions
    • Living Shoreline Protection Act (2008)
      • Requires non-structural shore protection practices unless proven infeasible
    • Chesapeake & Coastal Bays Critical Area Amendments (2008)
      • Increased vegetative buffers
      • Updated jurisdictional boundaries to account for sea level rise
      • Allows for consideration of coastal impacts during growth allocation decisions
  • 13.
    • Adaptation strategies are short to long-term actions, policies and/or management practices to reduce the vulnerability of natural and human systems to anticipated impacts of climate change.
    • The objective of many adaptation strategies is to reduce vulnerability by enhancing or increasing the resiliency of natural or human- systems to accommodate or withstand change over time.
    • In the context of coastal land conservation, adaptation strategies can be implemented through land conservation practices (i.e., preserving wetlands or habitat migration corridors).
