This week we talked with Dr Robert Jacobel, Professor of Physics Emeritus at St Olaf College and a geophysicist who has been working in the US Antarctic Program since 1987.
Spring (green) and summer (red) Arctic ice (1870-2011). Note the general trend toward less ice.
More continuous data – note seasonal up and down but trend down over time.
One example glacier. Landsat photo with overlay of the “calving front” of the glacier. This is a flowing ice field that grows out of the ice “cap” on Greenland. Note the receding ice line.
