Significant changes in climate are likely even if large and immediate cuts in emissions occur, due to the lingering effect of most greenhouse gases.

Conserving biological diversity will require creating conditions that will allow organisms to adapt to these changes.

Two important steps:

  1. Vulnerability assessment: evaluates the relative vulnerability of terrestrial and aquatic bird habitats to climate change
    • Identifies the species or systems that are most at risk from projected climate changes and the reasons underlying their vulnerability.
    • Necessary both for developing appropriate responses to climate change and prioritizing their implementation.
  2. Adaptation strategy: identifies approaches most likely to maximize resilience and maintain ecosystem functions.
