These goats seems to be well-trained. Even without a herder persent, they knew which way to go.
High mountain pastures are part of Austria’a agricultural tradition.
With snow in the forecast, sheepherders prepare to move their animals down to the valley.
This past summer, we spent several weeks exploring the world of Austrian Alms, high mountain pastures that are only grazed for a few months each summer. While we in the U.S. generally tend to prefer undisturbed mountain landscapes for their aesthetic and environmental values, these Austrian pastures have been grazed for centuries and even millennia. In the earliest days, as humans colonized the Alps after the last ice age, they had to use the higher slopes as forage areas because the valleys were still choked with glacial debris, wetlands and thick vegetation. That means the open meadows higher up were actually available for animal husbandry earlier than the lower elevations. In any case, the Alms now form an important part of the Alps’ ecological fabric, providing habitat for many wildflowers, including rare orchids, that wouldn’t thrive in a dark forest environment. Alms are also important to culture and recreation, as gathering points for hikers, and help ensure local food supplies.

Uptick in tropical cyclones intensifies impacts, hampers recovery
Along with the widely reported bleaching threat from over-heated oceans, coral reefs in many parts of the world also may have to cope with intensifying tropical storms, which could make it even more difficult for them to survive the Anthropocene.
Some of the biggest waves on record took a toll on beaches
The 2015-16 El Niño may have been a bust as far as precipitation in California, but it still ended up as one of the strongest episodes of the last 145 years, according to U.S. Geological Survey scientists who studied erosion along the West Coast.
They found that, on average, erosion was 76 percent above normal, with most beaches in California eroded beyond historical extremes. If, as some research suggests, El Niños become stronger in a warming climate, then the West Coast, with its 25 million inhabitants, will become increasingly vulnerable to coastal hazards.
The study covered seasonal changes at 29 beaches from Washington to Southern California. They used 3-D maps and aerial lidar imaging, GPS topographic surveys, and direct measurements of sand levels, combined with wave and water level data to measure the changes.
Winter beach erosion or the removal and loss of sand from the beach is a normal seasonal process, but the extent of erosion can be more severe during El Niño events than in other years.
New study shows warmup will boost methane releases
Small ponds could end up having a huge impact on Earth’s climate as they warm up due to heat-trapping greenhouse gas pollution, according to scientists from the University of Exeter and Queen Mary University of London. The researchers experimentally warmed a number small ponds by about 4-5 degrees Celsius over the course of seven years to study the effects of increased temperatures.

Even if precipitation stays the same or increases slightly in the next few decades, Colorado River flows are likely to dwindle due to increasing temperatures in the West. The projected warming in the 21st century could reduce flows by half a million acre feet per year, according to a new study to be published in the AGU journal Water Resources Research.

Along with recording the third-highest global average January temperature, scientists with the World Meteorological Organization have been tracking the Polar equivalent of heatwaves, as strong Atlantic storms driving temperatures in the Arctic to near freezing, at times 50 degrees Fahrenheit above the seasonal average.
The Gjaidalm, at a Bronze Age grazing site in the Austrian Alps, now serves mainly as an outpost for hikers and also offers yoga classes and wellness retreats.
Global warming is radically changing the chemistry of mountain soils and some plants that rely on a specific combination of nutrients are unlikely to survive.
Wilderness as its understood in the U.S. is a relatively new concept in Austria, but resource manageres are determined to recreate wilderness in the remote mountain forests around the Dürrenstein.
Mountain pastures in Austria help ensure local food security.
Global sea ice has been at a record low extent for several months. This aerial shot of Greenland, taken from a commercial flight, shows a receding glacier along the east coast of Greenland.
I’ve been reporting on the environment for 21 years, so it’s not surprising that, even when I’m traveling on vacation, I tend to see nearly everything through a certain prism. That may be a blessing and a curse at the same time. It might be nice, every now and then, to completely tune out from the world’s problems and just live hedonistically. On the other hand, I feel like I can really connect with the people and places I’m seeing by understanding them in an environmental context. And in reality, I don’t really separate work and play all that much anymore. This past summer’s trek through the Austrian Alps to learn about climate change and sustainable mountain agriculture was a wonderful experience. Being a journalist gives me an excuse to exercise my curiosity.
