The Climate of 1997
Annual Global Temperature Index
Please note: the estimate for the baseline global temperature used in this study differed, and was warmer than, the baseline estimate (Jones et al., 1999) used currently. This report has been superseded by subsequent analyses. However, as with all climate monitoring reports, it is left online as it was written at the time.
The global average temperature of 62.45 degrees Fahrenheit for 1997 was the warmest year on record, surpassing the previous record set in 1995 by 0.15 degrees Fahrenheit. The chart reflects variations from the 30-year average (1961-1990) of the combined land and sea surface temperatures.
