Question
Plot the global average temperature for the years 1960 to 2005 (Columns C and D). Use an XY Scatter with lines connecting the points.
A linear fit curve (y=mx+b) can be fit through this data and used to make predictions. The linear fit for this data is y=0.0133-12.292.
1. Based on this equation, what will the global average temperature be in the year 2020? Substitute 2020 into the equation for the x value and solve. Type in your answer and round to 2 decimal places.
If you were a climate scientist and asked to predict what the temperature will be in 2020, which linear model would you use? Would you use the linear model from the 1880 to 2005 data or would you use the linear model from the 1960 to 2005 data? Justify your answer. Either answer is acceptable as long as you justify the choice
Task 4. Sort the data in columns G and H to help answer the following questions. During which decade did the five warmest years in the record occur?
Select one:
a. 1965-1975
b. 1935-1945
c. 1985-1995
d. 1995-2005
Explanation / Answer
my choose:
c. 1985-1995
