IPCC Fourth Assessment Report: Climate Change 2007
Climate Change 2007: Working Group II: Impacts, Adaptation and Vulnerability

14.1.2 Key differences from TAR

This assessment builds on the findings from the TAR and incorporates new results from the literature, including:

  • Prospects for increased precipitation variability, increasing challenges of water management.
  • The need to include groundwater and water-quality impacts in the assessment of water resources.
  • The potential that multi-factor impacts may interact non-linearly, leading to tipping points.
  • The potential importance of interactions among climate change impacts and with other kinds of local, regional and global changes.
  • The potential for adaptation, but the unevenness of current adaptations.
  • The challenge of linking adaptation strategies with future vulnerabilities.
  • Availability of much more literature on all aspects of impacts, adaptation and vulnerability in North America.
