age of unmanaged land use as proxies for challenges to adaptation.*
Kriegler et al. (2011) and CWT (2011) dene challenges to adaptation in
terms of a xed climate change and challenges to mitigation in terms of a

greater if exposure and sensitivity to climate change are higher and if adap-

higher if the mitigation required to achieve any given radiativ ...
