Summary of Remarks: Each month NOAA provides an update of global and national temperature trends and anomalies. The results of these analyses have been used in IPCC and National Assessments to assess changes of temperature in the historical record. The methods and data used at NOAA's National Climatic Data Center to calculate the trends and anomalies will be discussed. This includes historical changes in data coverage, processing techniques, bias corrections, and assessments of uncertainty. When viewed with independent methods and data used by other agencies and governments to track temperature and temperature-related changes, the results have provided the basis for the statement "global warming is unequivocal."
