NBC interviews UAA researcher on global warming

The NBC news crew, led by weekend anchor Lester Holt, arrived to a fresh layer of snow when they landed in Anchorage last week. Holt, who spent a few years of his childhood in Anchorage, taped an interview with UAA's Vice Provost for Research, Douglas Causey, on global warming and the melting of glaciers in Alaska.

Recorded at the face of Spencer Glacier, this segment will air on the "Today Show", 5-7 a.m., NBC (KTUU Channel 2) and NBC Nightly News, 5:30 p.m., NBC (KTUU Channel 2) on April 26 and April 27. Holt also traveled to Fairbanks to do a piece on the Chena Hot Springs.
