Why is it difficult to determine accurately the long-term temperature trend?
What will be an ideal response?
Problems exist with historical temperature data. For instance:
Location of stations: Stations located in cities are subject to a "heat island effect" that causes local temperatures to increase with time.
Coverage in time and space: Some parts of the world have more coverage than the others. There is very little coverage, for example, in the southern oceans.
