High levels of an element found in coal ash have been detected in fish in two lakes where Duke Energy coal-fired power plants are located, according to a peer-reviewed study at Duke University. The element, selenium, occurs naturally but is concentrated in coal ash.

Floating Solar
Installing solar arrays on the surface of bodies of water is an idea that is catching on around the world. Such installations are especially attractive in places like Japan, where land resources are scarce. In the UK, there are a couple of these so-called “floatovoltaic” projects underway – one outside of London and one near Manchester.
Less Sulfur In The Soil
Acid rain is rain containing high levels of nitric and sulfuric acids. The main culprit for it is the burning of fossil fuels, particularly coal-burning power plants. The most serious effect of acid rain is the creation of toxicity in lakes, wetlands and other aquatic environments, doing great harm to a wide range of aquatic animals.
Road Salt
Snow season is here. The chances are good you’ll find yourself behind a truck spreading salt on the roads in an attempt to deice them. You may even try a little salt on your own front porch. Annually we spread about 20 million tons of road salt in the U.S., and we’ve been doing it since the late 1930s.
The World’s Lakes Are Heating Up
Climate change is causing the world’s lakes to warm, with repercussions for fisheries and freshwater supplies. So reports an ambitious new study, funded by NASA and the National Science Foundation, and recently published in Geophysical Research Letters.
Climate Change And The Global Food System
One of the most troubling aspects of global climate change is its potential impact on the production, distribution and quality of food. A report issued at the 2015 Paris Climate Conference focused on identifying climate change impacts on global food security. Food security is the ability of people to obtain and use sufficient amounts of safe and nutritious food. Even without the impact of climate change, food security is a challenge because of increasing population, poverty, and changing eating habits.

Microplastics And Salt
Today, thousands of personal care products – such as facial scrubs, body washes, and toothpastes – are known to contain minuscule balls of plastic called microbeads. When we shower or brush our teeth, these microbeads are washed down the drain and travel undetected through wastewater treatment plants. When they reach their final destination — our lakes, rivers and oceans — they mix with other sources of microplastics, including industrial waste and degraded plastic litter.
