Average Surface Temperature Data The GISS Surface Temperature Analysis (GISTEMP)

Question

Average Surface Temperature Data The GISS Surface Temperature Analysis (GISTEMP) is an estimate of global surface temperatures. The data for average surface temperatures are deviations from the average temperatures measured between 1951-1980. Negative numbers indicate below average temperatures from that time period, while positive numbers indicate temperatures above the average. For example, in 1996 the average surface temperature was +35, which indicates mean annual temperature in 1996 was on average was 0.35 "C higher than between 1951 to 1980 Record the January-December (J-D) annual mean temperature from 1996 to 2015. The NASA surface temperature data is located at: https://data.giss.nasa.gov/sistemp/. Scroll down to data under the heading: Combined Land-Surface Air and Sea-Surface Water Temperature Anomalies (Land-Ocean Temperature Index, LOTI). Global-mean monthly, seasonal, and annual means, 1880-present, updated through most recent month Select the TXT file link and record mean annual temperatures (J-D) in the table below.
