Geophysical Institute researcher Regine Hock and her colleague Valentina Radic have calculated that the rate of sea-level rise due to the meltwater from glaciers in Alaska and elsewhere will increa

My notebook is full from my visit to the American Geophysical Union’s Fall Meeting in San Francisco, which convened for a week in December 2010. Here’s some Alaska-related news:

An image of comet Hartley 2 from NASA’s EPOXI mission. The image was taken as the spacecraft flew by the comet on November 4, 2010. According to NASA, the Hartley 2 comet is 1.4-miles-long and is composed of water ice, carbon dioxide ice and silicate dust. The name “EPOXI” is a combination of the names Extrasolar Planet Observations and Characterization (EPOCh) and Deep Impact Extended Investigation (DIXI).
