Give a clear explanation
Key Question #12 Use the graph below to answer the following questions. The temperature values in the data set are provided as differences from a mean of 15 degrees C. These e been analyzed by scientists to show a 0.5 degrees C increase in global temperatures. However, large to justif o Data was collect o For each year data has been averaged to come up with a yearly average thls finding is under dispute because some claim that the amount of error in the data is too y the conclusion. This data set has been created using the following steps: ed from land based stations, from ocean buoys, and from ships. o Data is smoothed to accommodate historical changes that skew the data (e.g., weather stations near cities record artificially high temperatures because create what is called an "urban hea t island effect.") Global Temperature Difference from 15 C D 0.2 D.-4 -0.6 340 1860 1880 1900 1920 1940 960 1980 2000 State a generalization that interprets this data and incorporates time and temperature from the graph aboveExplanation / Answer
from above time series plot it is observed that upto year 1940 the average globle temperature is less than 15 C and is 14.7 C. Between the year 1940 to 1980 the temperature is increased by 0.2 to 0.3 C and after 1980 the globle temperature is increased and is about 15.2 to 15.3 C. hence the globle temperature in increased by 0.5 C.
