For millennia, snowshoe hares have camouflaged themselves from predators by blending in with their surroundings, turning pure white in the winter to blend in with the snow, then brown in the summer.
But climate change is shifting the timing of the snow season, and the hares may not be able to adapt in time, according to a North Carolina State University study published in the journal Ecology Letters.
Based on field research with radio-collared snowshoe hares in Montana, mismatched snowshoe hares suffer a 7 percent drop in their weekly survival rate when snow comes late or leaves early and white hares stand out to predators like “light bulbs” against their snowless backgrounds.

Morning light warms up the broad flanks of Buffalo Mountain.
There’s pure magic in the deep, cold heart of winter, especially during the golden hour, when the rising or setting sun can be playful, mysterious and perplexing. The images in this set capture a bit of that magic, but there’s so much more. #getoutside #explore and don’t forget your camera!

El Niño has been generous to Colorado this winter, favoring all of the state with near- to above-normal precipitation since the beginning of winter. As of Jan.1, nearly all the state’s river basins were above average, with only the North Platte and the Yampa drainages lagging slightly below normal.
Some past El Nino events have been known to leave the northern half of the state high and dry.
New research project to assess how Greenland ice sheets responded to past changes in precipitation
FRISCO — There’s little question that global warming will drive significant melting of the world’s ice sheets, but it’s not clear exactly how fast that meltdown will happen.
Some climate models suggest that warmer ocean temperatures will lead to more snowfall over the Arctic — and that could slow the rate melting of glaciers and the rate of sea level rise, according toJason Briner, an associate professor of geology in the University at Buffalo College of Arts and Sciences.

Drying grasses and shrubs up fire danger in parts of Colorado
FRISCO — Summer may be winding down, but the wildfire season is not over yet. In the past ten days, fire managers and park rangers at Rocky Mountain National Park have responded to four illegal, escaped campfires.
