Details

From https://www.ncdc.noaa.gov/cag/global/data-info: "Global temperature anomaly data come from the Global Historical Climatology Network-Monthly (GHCN-M) data set and International Comprehensive Ocean-Atmosphere Data Set (ICOADS), which have data from 1880 to the present. These two datasets are blended into a single product to produce the combined global land and ocean temperature anomalies. The available timeseries of global-scale temperature anomalies are calculated with respect to the 20th century average."

Examples

# We downloaded this data and created the `NHTemp` dataframe with the following code:
if (FALSE) {
library(RCurl)
ww1 <- "https://www.ncdc.noaa.gov/cag/time-series/"
ww2 <- "global/nhem/land_ocean/p12/12/1880-2014.csv"
NHTemp <- read.csv(text=getURL(paste0(ww1,ww2)), skip=4)
save(NHTemp, file="NHTemp.RData")
}
