Global (January-December) average air temperature anomalies from NASA: https://data.giss.nasa.gov/gistemp/
So you don’t have to import, read or type the data values in for the global surface air temperature anomalies from NASA, we have made a convenient array for you to copy and paste:
let rawData = [ -16, -8, -10, -17, -28, -32, -30, -35, -16, -10, -35, -22, -26, -31, -29, -22, -10, -10, -26, -17, -7, -15, -28, -37, -47, -26, -22, -39, -43, -48, -43, -44, -36, -35, -16, -14, -36, -46, -30, -28, -28, -19, -28, -27, -27, -22, -11, -22, -20, -36, -16, -10, -16, -29, -13, -20, -15, -3, -1, -2, 12, 18, 6, 9, 20, 9, -8, -3, -11, -11, -18, -7, 1, 8, -13, -14, -19, 5, 6, 3, -2, 6, 4, 5, -20, -11, -6, -2, -8, 6, 3, -8, 1, 16, -7, -1, -10, 18, 7, 16, 26, 32, 14, 31, 16, 12, 18, 32, 38, 27, 45, 40, 22, 23, 31, 45, 33, 46, 61, 39, 40, 54, 62, 62, 54, 68, 64, 66, 54, 66, 72, 61, 64, 68, 74, 90, 101, 92, 85]
