Sea ice decline spurs the greening of the Arctic
Sea ice decline and warming trends are changing the vegetation in nearby arctic coastal areas, according to two University of Alaska Fairbanks scientists.
Uma Bhatt, an associate professor with UAF’s Geophysical Institute, and Skip Walker, a professor at UAF’s Institute of Arctic Biology, contributed to a recent review of research on the response of plants, marine life and animals to declining sea ice in the Arctic.

In early August 2013 a strange group of scientists who are hooked on light refraction met in Fairbanks to discuss their techniques and findings of optical phenomena found in nature. The Light and Color in Nature workshop lasted for four days and brought scientists from around the world to discuss halos, rainbows, sundogs and even light refracted by a spider's web.

In warm Alaska summers like this, in which Fairbanks has set a record for most 80-degree Fahrenheit days and Anchorage has exceeded 70 with similar frequency, rainfall has been a phenomenon many people have not missed.

Fairbanks, Alaska—Ever wonder how light and color reflect in a rainbow or a sundog?
Taking to the sky to better sniff the air

On a cool spring morning in the mountains of southwest Washington, 12-year old Cathy Cahill helped her dad plant scientific instruments around the base of trembling Mount St. Helens. A few days later, the volcano blew up, smothering two of his four ash collectors. When he gathered the surviving equipment, Cathy’s father found a downwind sampler overflowing with ash laced with chlorine. Tom Cahill of the University of California, Davis, wrote a paper on this surprising result; editors at the journal Science were impressed enough to publish it.
