Choosing the data stream that shows 1998 to be the warmest on record may be somewhat artificial, but it is probably the best data available, and is widely accepted as the basis for global warming forecasts.

The data source that puts 1998 as the warmest year is UAH MSU:

Many other reputable data sources put it later than that:
Nasa's GISS puts it as 2005
http://data.giss.nasa.gov/gistemp/graphs/Fig.A2.txt
NCDC's data also put it as 2005

Oh, and all the hacked emails talk about is making the graphs look more convincing or more alarming. At no point they talk about data falsification or manipulation.
