Big chunks of Louisiana’s coast will be swallowed by the sea within decades unless there’s a major effort to rebuild wetlands. Over the last six to 10 years, sea level has been rising about .5 inches per year on average in the region, according to Tulane University researchers, who recently published a new study in the journal Nature Communications .
“In the Mississippi Delta, about 65 percent of study sites are probably still keeping pace, but in the westernmost part of coastal Louisiana, more than 60 percent of sites are on track to drown,” said Tulane geology professor Torbjörn E. Törnqvist, a co-author of the study. Continue reading “Swallowed by rising seas”→
An international research team says monsoon storms in the Southwest have become less frequent but more intense, bringing more extreme wind and rain to central and southwestern Arizona than just a few decades ago.
The study, led by scientists with the University of Arizona, compared precipitation records from 1950 to 1970 with data from the 1991-2010 period to verify their climate model, scaled down to capture changes at a resolution of 1.5 square miles. At that level of detail the changes over time became apparent, while models using a 10 square mile grid aren’t able to accurately recreate the precipitation trends.

Ripening grain and a poppy field in full bloom near Bad Traunstein.
At an elevation of about 1,000 meters in the Waldviertel, a poppy field blooms in mid-July.
Austria a densely populated country, but there are some wide open spaces. Just have to know where to look!

There’s a perception that Austria is a densely populated country, especially if your main impression comes from visiting tourist centers like Vienna or Salzburg. But in reality, the country ranks about in the middle of EU countries in terms of density, at 97 people per square kilometer. That’s a little higher than Greece (81) but lower than, for example, Italy (192). That means there are some wide open spaces outside the population centers, including the sparsely populated Waldviertel region, north and west of Vienna, extending toward the border with Czechia. We captured a few landscape images in the region during a visit to the famed poppy fields, highlighted in last week’s photo essay.
Coal power plants still to blame for emitting most of the toxic mercury pollution
Mercury continues to build up in Arctic ecosystems at levels that threaten the health and well-being of people, wildlife and waterways in the region.
A new study that looks at the sources of the toxic metal shows that airborne mercury is gathering in the Arctic tundra, where it gets deposited in the soil and ultimately runs off into waters. Scientists have long reported high levels of mercury pollution in the Arctic. The new research identifies gaseous mercury as its major source and sheds light on how the element gets there.

Environmental attorneys are going to be busy the next few years under an onslaught of proposed fossil fuel development projects, including offshore oil and gas drilling.
As part of the Trump administration’s misguided push for “energy dominance,’ the federal government is preparing to create a new new nationwide offshore leasing plan that could open all U.S. waters to dangerous drilling. Last week, the administration said it will ask the fossil fuel industry where it wants to drill. Continue reading “Is offshore drilling coming to a beach near you?”→
