Answer the questions below. 1.)Describe the average temperature change from 1880 to 2019. 2.) Why is the curve between 1950 and 1980 relatively flat and centered around zero degrees difference from the baseline( hint: how the temperature change being compared over time ?) 3.) the grey shaded areas are called “error bars”. Why do you think these error bars are smaller in the late 1900s and 2000s than they are for the 1800s and early 1900s? 4.) why is the black line so much more variable than the red line ? What’s the difference between the date they show ?
