Dan Kondel Honors Geoscience Summer Project Honors Geoscience Summer Project Task 3 Section 1: Earth’s changing climates 1. What do the colors indicate about the change in average temperature over time from 1884 to 2012? The colors indicated that the average temperature rose in all continents from 1884 to 2012. 2. In the past 50 years, where has the temperature changed the most? In the past 50 years, the temperature has changed the most in the northern part of the world. 3. Describe the average temperature change from 1880 to 2010. The average temperature changed 0.7 degrees celsius from 1880 to 2010. 4. Why is the curve between 1950 and 1980 relatively flat and centered around zero degrees difference from the baseline? (Hint: how is the temperature change being compared over time?) 5. The green bars are called "error bars." They indicate the range of uncertainty that scientists have about the data on the graph. (Note: Not all error bars are shown.) Why do you think these error bars are smaller near the year 2000 than in the 1890s? I think these error bars are smaller near the year 2000 than in the 1890s because the technology has advanced immensely since 1890. 6. Why is the black line so much more variable than the red line? What 's the difference between the data they show? The black line is so much more variable than the red line because the black line represents the annual average temperature and the red line represents the 5 year running average temperature. 7.
