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.

5 countries now on notice face potential legal action
By Bob Berwyn
Five large EU countries are on warning after repeatedly failing to meet air pollution standards for nitrogen oxide, a precursor to smog and a serious health risk in and of itself. If Member States fail to act within two months, the Commission may decide to take the matter to the Court of Justice of the EU.
Studies have shown that more than 400,000 people die prematurely each year due to poor air quality, while millions more suffer from respiratory and cardiovascular diseases. Persistently high levels of nitrogen dioxide (NO2) caused almost 70 000 premature deaths in Europe in 2013, which was almost three times the number of deaths by road traffic accidents in the same year.
Because of the persistent breaches, the European Commission this week sent final warning to Germany, France, Spain, Italy and the United Kingdom, urging those countries to improve air quality and safeguard public health.
The threat of roads to carnivore species around the world has been seriously underestimated, according to a new study that looked at the issue on a global scale.
After looking at 232 carnivore species around the world (out of a total of about. 270 existing species) and assessing how severely these are affected by roads cut through their habitat, the researchers concluded that some rare species are even at risk in areas with low road densities. The study, published in the journal Global Ecology and Biogeography, calculated natural mortality rates, reproduction and carnivore movement patterns, determining the maximum density of roads that a species can cope with.

Trump’s proposed Cuts to federal regulations likely to lead to more environmental woes
Coal ash waste is poisoning fish in North Carolina lakes, scientists said this week announcing findings from a new study supported in part by the EPA. The research by scientists from Duke University showed that potentially harmful levels of selenium are building up because of emissions from coal-fired power plants.
“Across the board, we’re seeing elevated selenium levels in fish from lakes affected by coal combustion residual effluents,” said Jessica Brandt, a doctoral student in environmental health at Duke’s Nicholas School of the Environment, who led the study, published this month in the journal Environmental Science & Technology.

Time revisit a couple of favorite mountains scenes in the Summit Voice archives, and time to remember that global warming is going alter some mountain landscapes irrevocably, not it the far distant future, but within a few decades. For example, a new study shows how warming will alter basic soil chemistry by speeding up microbial activity and shifting the balance of key nutrients. This will displace some plants and probably eliminate others. And as much as we appreciate forested landscapes, climate change is driving the spread of tree-killing insects, as shown by the latest aerial survey of Colorado forests.
