There are two main policy responses to climate change: mitigation and adaptation. Mitigation addresses the root causes, by reducing greenhouse gas emissions, while adaptation seeks to lower the risks posed by the consequences of climatic change. Both approaches will be necessary, because even if emissions are dramatically decreased in the next decade, adaptation will still be needed to deal with the global changes that have already been set in motion.
This Primer focuses on the role that ICT can play in climate change adaptation and mitigation. Since climate and the environment are linked, this Primer also considers the role of ICT in helping humans understand the environment that surrounds them, which is a prerequisite for tackling the problems of climate change.
