UNFCCC definition of climate change
A change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods

3 reasons for scenario analysis and why difficult?
Historical data is insufficient
Does not rely on linear or historical trends but models integrated economic and climate effects
Interactions with many other issues and feedback loops
