A quick flashback set featuring winter scenes from the Rocky Mountains of Colorado. It’s not always that easy to get motivated for a photo session when it’s below freezing outside, but it’s always worth it when you do, because, well, there are some things that you can only see in winter — delicate ice filaments forming on the surface of a creek that somehow manages to keep flowing through sub-zero air, or a winter storm clearing just in time to give way to the warm orange glow of sunrise. And it’s always fun to take a look at the structure of ice. So don’t put away your camera when the weather gets chilly. Just make sure your batteries are fully charged

Not as much content as usual on Summit Voice this week, but that’s because we were busy reporting elsewhere, with a few noteworthy stories. For example, Austria is holding a presidential election tomorrow (Sunday, Dec. 4) and the election of Donald Trump became an issue in the last few weeks of the campaign. I co-reported a story on the election with the European bureau chief of the Christian Science Monitor, including an interview with an American expat involved in the campaign.
‘No ship captain or shipping company wants to strike a whale’
Satellite data about whale movements and ocean conditions have helped scientists create monthly whale hotspot maps that could help avert collisions between ships and marine mammals.
Developed by researchers with NOAA Fisheries, Oregon State University and the University of Maryland, the WhaleWhatch program alerts ships where there may be an increased risk of encountering these endangered whales. NASA helped fund the project, which draws on ocean observations from NASA and NOAA satellites. Continue reading “Satellite mapping could help avert whale-ship crashes”→
Scientists eye winter ecosystems in ice-covered lakes
A team of international scientists who studied more than 100 lakes during the winter said there’s more going on beneath the ice than we realized. Their findings stand to complicate the understanding of freshwater systems just as climate change is warming lakes around the planet, and shortening the ice season on many lakes. Other parts of the planet’s cryosphere are also melting under the thickening layer of heat-trapping greenhouse gas pollution.
“As ice seasons are getting shorter around the world, we are losing ice without a deep understanding of what we are losing,” said Stephanie Hampton, a Washington State University professor and lead author of a new study published in the journal Ecology Letters. “Food for fish, the chemical processes that affect their oxygen and greenhouse gas emissions will shift as ice recedes.” Continue reading “Life under the ice”→
Northern section hammered by warm ocean temperatures
Australian researchers this week released results of their latest Great Barrier Reef surveys, concluding that huge swaths of coral died in the past year under the onslaught of an ocean heatwave that led to widespread coral bleaching.
‘There is nowhere to go because they’re literally at the top of the continent … ‘
The findings of a new 20-year study suggest what already appeared obvious — that certain insects reliant on cold water from glaciers and snowmelt are endangered from global warming. The U.S. Geological Survey research focused on two stonefly species in Montana, and will be used to inform the status review for consideration of protection under the U.S. Endangered Species Act .
Most of my photography focuses on natural landscapes, and I often try to set up and compose images to avoid human intrusion. That’s because I figure the human species has pretty much become a destructive parasite on the Earth, for the most part only taking, without giving anything back. But there are places where people live in harmony with their surroundings; where structures are built on a scale that doesn’t suggest dominance. I found a few places like that this summer while touring around Austria doing research for the Global Warming in the Alps project, for example the roadside farmhouse nestled into the hillside in the first image, or the Almtalerhaus, a mountain refuge and restaurant in the Salzkammergut lakes region of Upper Austria. As well, the Dachstein Lodge am Krippenstein is a rebuilt shelter that fits well on its mountaintop perch, rather than looming ostentatiously over the slopes like so many other new mountain lodges. We’re all going to have to try and live on a more human scale if we’re going to get serious about creating a sustainable future for our kids.
