Beetle kill linked to warmer temperatures

Bark beetles make regular headlines in Colorado, but the copper-hued forests they are creating now stretch from the Centennial State all the way into the heart of the Canadian Rockies of British Columbia and Alberta.

At a Society of Environmental Journalists conference last month in Montana, Glacier National Park officials said that the park, which with its fast-melting glaciers is becoming the poster child for the effects of climate change in North America, is beginning to see the very first signs of its own bark beetle troubles.

Though the reasons for the bark beetle outbreak throughout the Rockies are complex, many scientists in the region say one of the primary causes of the outbreak is warmer winter temperatures.
