https://www.climatelevels.org/ Access the Global Temperature Record graph by launching the Climate Dashboard < https://www.climatelevels.org/ >. Click on the graph in lower left corner of the set of six graphs that appear and activate the little menu in the right corner, choosing "Detailed Graph with options". What you see when you do so should look like figure 1. Since this graph only goes back a thousand years you will need to click on the clock icon in the upper left corner of the frame 1. What and when were the highest and lowest temperatures during the past 800,000 years? Once you have accessed the temperature graph for the past 800 millennia use it to address the following questions. 2. How do the highest and lowest temperatures compare to the most recent temperature? 3. Between 123,000 and 22,100 years ago what were the highest ad lowest temperatures? How would you describe the temperature variations between these two times? 4. What happens to mean global temperature (MGT) after 22,100? 5. How is the temperature variation between 330,000 and 270,00 years similar to what happened between 123,000 and 22,100 years ago? 6. Find at least three other time periods that show similar trends to the two periods mentioned in the previous question. When were they and what were their maximum high and low temperatures? 7. On the graph, troughs correspond with periods of cooling and glacial advance (glacials), while peaks correspond with periods of warming and glacial retreat (interglacials). For each of the periods listed in questions 5 and 6 how many glacials and interglacials did you count in each period? 8. Based on what you observed for questions 4 and 5 what kind of temperature variations would you expect to see on the planet during the next 100,000 years? http://www.temperaturerecord.org/?theme=grid-light&pid=2degreesinstitute
