These data contain monthly mean temperature anomalies expressed as deviations from the corresponding 1951-1980 means. They are useful for showing how we can measure climate change.
Format
A data frame with 1,716 observations on the following 2 variables.
datea date, mostly to contain information for the year and month
valuethe mean temperature anomaly as deviation from corresponding 1951-1980 mean
Details
Data are updated through most recent month, at least for last time I updated it.
Data represent combined land-surface air and sea-surface water temperature anomalies.
Of note: the day value in the date column has no real value.
It was just a way of combining data that are aggregated by year and month.
