Scientists track decline of iconic Galápagos birds
FRISCO — Populations of blue-footed boobies, one of the Galápagos Islands iconic species, have dwindled by a third since the 1960s, mainly because the birds don’t seem to be finding the food…
A new study of Greenland ice cores suggests parts of the ice sheet persisted through previous global warming spells.
Will there be a meltdown?
FRISCO — At least some parts of the Greenland ice sheet likely survived some of the warmest interludes in the Earth’s geologic climate history, researchers said last week as they announced findings of a study that discovered an ancient tundra…
Findings shed new light in links between temperatures, CO2 and glaciation
How will Antarctic ice sheets and glaciers respond to global warming? bberwyn photo.
FRISCO — The relationship between global temperatures and the massive glaciation of historic ice ages may be a bit more complex than previously believed.
By studying the chemical composition of Mediterranean Sea fossils as old…
Valley snow is melting fast
Twilight hike on Ptarmigan Mountain, Summit County, Colorado.
FRISCO — You know it was going to happen one of these days — even the biggest snow berms from the winter are melting down and hikers say that some local trails are already starting to dry out. That’s the case along the Ptarmigan Mountain Trail, where the first pasqueflowers of the season are blooming just in…
It ain’t over until it’s over
Skiing through a clearing April storm near Frisco, Colorado.
FRISCO — Sometimes I group photos geographically, or post a series of images from one shoot, but today’s set is all about diversity, in a photographic sense — color, texture, hue … we have such an incredible palette to choose from, especially with a digital darkroom.

Last year’s ozone hole over Antarctica was the second-smallest in 20 years, according to NASA.
CFC ban showing signs of success
FRISCO — Scientists say it’s unlikely that the Arctic will see ozone depletion on the scale of the Antarctic ozone hole, thanks mainly to international efforts to limit ozone-killing chemicals.
“While there is certainly some depletion of Arctic ozone, the…
Springtime in the Rockies
FRISCO — I’ve always thought spring snowstorms were different. The snow is wetter, and often starts when air temperatures are (relatively) warm. That means the snow sticks to everything, including vertical surfaces, and hangs on even if there’s a bit of a breeze. So, even if the weather turns springlike, that snow clinging to the trees makes it look wintrier than…

At the edge of the meadow.
FRISCO — A couple of quick jaunts through Summit County this weekend yielded a few decent snapshot, including the muted sunset in the first image, brought to life with th iPhone’s HDR option, not to mention some Instagram editing. Along with the scenic shots of Summit County, I got up close and personal with a couple of roadside embankments, exploring…
Curbing global warming will require big cuts in greenhouse gases
March 2014 temperatures were above average across most of the globe.
By Summit Voice
FRISCO —Greenhouse gas emissions continue to climb despite international attempts to curb heat-trapping gases, the Intergovernmental Panel on Climate Change said in its latest climate report.
Issued Sunday in Berlin, the report shows that greenhouse…
