Online Tool Identifies Dangers of Toxic Coal Ash Impacting Your Community
On Dec. 11, Southern Alliance for Clean Energy, Appalachian Voices, Southern Environmental Law Center and North Carolina Conservation Network launched the first-ever comprehensive online tool that allows Southeast residents to find specific information about coal ash impoundments near them. The site includes information on the health threats associated with this toxic waste from coal-fired power plants, safety ratings of the coal ash impoundments and how citizens can advocate for strong federal safeguards.
Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina, South Carolina, Tennessee and Virginia are the nine states covered by the site, which is being launched almost four years to the week after a massive coal ash dam in Kingston, Tenn. catastrophically failed, releasing a billion-gallon flood of coal ash that poisoned some 300 acres, destroyed two dozen homes and filled the Emory River with toxic sludge. The coalition developed the website to call greater attention to the lurking dangers of coal ash in the South.
The Southeast is home to nearly 450 impoundments that hold 118 billion gallons of coal ash: enough to cover 300,000 football fields in 1 foot of toxic coal ash waste. These impoundments are veritable man-made lakes full of toxic compounds that threaten the waterways of the Southeast and the public with potential dam failures.
SoutheastCoalAsh.org offers concerned citizens throughout the region a new and easy way to learn if their community or drinking water source is in danger from these largely unregulated coal ash impoundments.
The website features an interactive map and database of 100 coal-fired power plants in the Southeast, color-coded by the amount of damage each would inflict if the coal ash dams were to break, according to the U.S. Environmental Protection Agency (EPA). Of the Southeast plants with dams rated by the EPA, nearly one-third are “high hazard,” meaning that a dam failure like Kingston would likely cause fatalities. A brief glance at the map shows just how much more work needs to be done to assess these dangers—almost half of the plants in the Southeast have inadequate data for the EPA to properly assess the coal ash dams on site. Moreover, many of the plants lack adequate water monitoring data to show whether or not there are contamination problems at these sites. The web tool puts a spotlight on the hidden dangers of numerous impoundments storing coal ash waste in the Southeast and helps people understand how pollution from this waste poisons the water they use for drinking, swimming, fishing and recreation.
The new website features more than a dozen informational pages detailing the health and environmental hazards of coal ash as well as the current legislative and regulatory environment, active legal battles, links to additional articles, news and more. Every coal-fired power plant in the Southeast has a site-specific page, accessible from the interactive map. One click takes you deeper into the data about each plant to find out if there are any known contamination problems at the coal ash impoundment(s) on site, local action groups you can contact about that plant, as well as other local, state and regional/federal actions citizens can take.
Sweden's reindeer have a problem. In winter, they feed on lichens buried beneath the snow. But the climate crisis is making this difficult. Warmer temperatures mean moisture sometimes falls as rain instead of snow. When the air refreezes, a layer of ice forms between the reindeer and their meal, forcing them to wander further in search of ideal conditions. And sometimes, this means crossing busy roads.

A chance discovery of a beautifully preserved fossil in the desert landscape of Morocco has solved one of the great mysteries of biology and paleontology: how starfish evolved their arms.
The Pompeii of palaeontology. Aaron Hunter, Author provided<h2></h2><p>Although starfish might appear very robust animals, they are typically made up of lots of hard parts attached by ligaments and soft tissue which, upon death, quickly degrade. This means we rely on places like the Fezouata formations to provide snapshots of their evolution.</p><p>The starfish fossil record is patchy, especially at the critical time when many of these animal groups first appeared. Sorting out how each of the various types of ancient starfish relate to each other is like putting a puzzle together when many of the parts are missing.</p><h2>The Oldest Starfish</h2><p><em><a href="https://www.biorxiv.org/content/10.1101/216101v1.full.pdf" target="_blank" rel="noopener noreferrer">Cantabrigiaster</a></em> is the most primitive starfish-like animal to be discovered in the fossil record. It was discovered in 2003, but it has taken over 17 years to work out its true significance.</p><p>What makes <em>Cantabrigiaster</em> unique is that it lacks almost all the characteristics we find in brittle stars and starfish.</p><p>Starfish and brittle stars belong to the family Asterozoa. Their ancestors, the Somasteroids were especially fragile - before <em>Cantabrigiaster</em> we only had a handful of specimens. The celebrated Moroccan paleontologist Mohamed <a href="https://doi.org/10.1016/j.palaeo.2016.06.041" target="_blank" rel="noopener noreferrer">Ben Moula</a> and his local team was instrumental in discovering <a href="https://www.sciencedirect.com/science/article/abs/pii/S0031018216302334?via%3Dihub" target="_blank" rel="noopener noreferrer">these amazing fossils</a> near the town of Zagora, in Morocco.</p><h2>The Breakthrough</h2><p>Our breakthrough moment came when I compared the arms of <em>Cantabrigiaster</em> with those of modern sea lilles, filter feeders with long feathery arms that tend to be attached to the sea floor by a stem or stalk.</p><p>The striking similarity between these modern filter feeders and the ancient starfish led our team from the University of Cambridge and Harvard University to create a new analysis. We applied a biological model to the features of all the current early Asterozoa fossils in existence, along with a sample of their closest relatives.</p>
Cantabrigiaster is the most primitive starfish-like animal to be discovered in the fossil record. Aaron Hunter, Author provided<p>Our results demonstrate <em>Cantabrigiaster</em> is the most primitive of all the Asterozoa, and most likely evolved from ancient animals called crinoids that lived 250 million years before dinosaurs. The five arms of starfish are a relic left over from these ancestors. In the case of <em>Cantabrigiaster</em>, and its starfish descendants, it evolved by flipping upside-down so its arms are face down on the sediment to feed.</p><p>Although we sampled a relatively small numbers of those ancestors, one of the unexpected outcomes was it provided an idea of how they could be related to each other. Paleontologists studying echinoderms are often lost in detail as all the different groups are so radically different from each other, so it is hard to tell which evolved first.</p>
