Surface Air Temperature (IMAGE)
Caption
This graph depicts high-latitude (60°-90°N) surface air temperatures under different conditions simulated in the study over a 50 year period. The solid black line indicates current carbon dioxide levels, the solid red line depicts four times preindustrial carbon dioxide levels, the blue dashed line represents alterations imposed to increase reflection of sunlight energy back into space north of 70°N, the brown dashed line represents alterations imposed to increase reflection of sunlight energy back into space north of 80°N, the purple dashed line represents alterations imposed to increase reflection of sunlight energy back into space between 70 and 80°N. Boxes on the right show the mean (with two standard errors) while whiskers indicate min/max range over the last 30 years.
