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.

Between 2005 to 2015, surface melt off ice caps and glaciers of the Queen Elizabeth Islands grew from an average of three gigatons to 30 gigatons
The Greenland Ice Sheet isn’t the only place melting under a thickening blanket of heat-trapping greenhouse gases. A new study shows that Canada’s Arctic glaciers are also shedding ice at a rapidly increasing rate, making them a big factor in global sea level rise.
In a new study, glaciologists with the University of California, Irvine said that, between 2005 to 2015, surface melt off ice caps and glaciers of the Queen Elizabeth Islands grew by 900 percent, from an average of three gigatons to 30 gigatons per year, according to findings published last week in the journal Environmental Research Letters.

Just small increases in ocean temperatures during past geological epochs may have been enough to tip Northern Hemisphere ice sheets toward disintegration, even as air temperatures remained cold. That could spell trouble in the current era of climate warming, according to a new study led by University of Michigan researchers, who said their finding suggest that climate change could cause sea level to rise higher than most models predict.

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.
