Document Summary
Instructions: students are encouraged to work together, but each must turn in their own individual work. When asked to write, please use complete sentences. The total number of points possible is 35. This assignment is worth 3. 5% of the final grade. These data are measured using ice core samples drilled from the ice sheet in antarctica. The temperature axis is on the left and the co2 axis is on the right. The bottom axis shows years before present (0). Scientists often use these data to talk about global warming and climate change: {4pts} describe the main factor(s) controlling the variability in temperature over this record. The main factors controlling the variability in the temperature over this record are the milankovich cycles, which include orbit shape, tilt, and wobble of the earth. Orbit shape of the earth effects the amount of solar radiation coming into the earth(cid:495)s atmosphere in the northern hemisphere. The tilt of the earth(cid:495)s access affects the seasons.
