The Common Sense Climate Index (Hansen et al. 1998) is a simple
measure of the degree (if any) to which practical climate change is
occurring. The index is a composite of several everyday climate
indicators. It is expected to have positive values when warming occurs
and negative values for cooling. If the Index reaches and consistently
maintains a value of 1 or more, the climate change should be
noticeable to most people who have lived at that location for a few
