The purpose of this report is to compile and summarise the present knowledge on impacts of climate change as a basis for a consideration of what may constitute dangerous anthropogenic interference with the climate system under Article 2 of the United Nations Framework Convention on Climate Change (UNFCCC). An attempt will be made to associate projected global mean surface temperature and/or sea level changes with specific identified impacts and effects in order to assist a discussion on the operationalization of Article 2. The main emphasis will be on ecosystem effects, food production, water resources, and sustainable development.
