Steam produced by underground heat is an excellent source of clean energy.  In a few fortunate places around the world – notably Iceland and New Zealand – people have been using this source of power for more than a century.   In the U.S., a few places in the West have access to geothermal energy, and […]

A few years ago, researchers investigating massive deaths of coho salmon in West Coast streams discovered that the water contained particles from vehicle tires.  The cause of the fish mortality turned out to be a chemical called 6PPD that is added to tires to prevent cracking and degradation.  The mystery was solved, but so far, […]

It was a very rainy and relatively cool summer in much of New England as well as in New York’s Capital Region, where Earth Wise originates.  Despite that fact, according to NASA scientists, the summer of 2023 was the Earth’s hottest since global record keeping began in 1880. The months of June, July, and August […]

Human history has often been described in terms of a succession of metal ages:  the copper age, the bronze age, and the iron age.  In many ways, we have now entered the lithium age.  The light metal goes into the batteries that power smartphones, electric vehicles, and massive storage banks for the power grid.  Lithium […]

Our planet is heating up.  Scientists have concluded that the changing climate is primarily the result of increased greenhouse gas emissions from human activities.  Some of the effects of global climate change include thawing permafrost, rising seas, intensifying storms and wildfires, and warming oceans.    According to a new study led by researchers from Penn State […]

An international study led by researchers from Austria has developed a novel way to store energy by transporting sand into abandoned underground mines.  The technique is called Underground Gravity Energy Storage or UGES. As the world deploys growing amounts of wind and solar energy, it is increasingly important to find ways to accessibly and efficiently […]

Glaciers are sensitive indicators of climate change that respond to changes in both temperature and precipitation.  But they are not only affected by climate change, they also affect climate change.  As glaciers melt, they contribute to sea level rise, alter regional hydrology, and influence the global energy balance. A group of glacier experts from the […]

Northern White Rhinos are virtually extinct; only two female individuals survive in Kenya.  Southern White Rhinos also nearly vanished early in the 20th century, mostly because of excessive hunting.   A surviving group of fewer than 100 animals was identified in South Africa, and ongoing conservation efforts led to the existing population of southern white rhinos, […]

By the end of August, the United States had already broken the one-year record for the number of weather and climate disasters that caused more than $1 billion in damage. According to the National Oceanic and Atmospheric Administration, through August there had already been 23 billion-dollar disasters.  The previous record of 22 had been set […]

The environmental cost of plastic waste is a highly visible global issue.  The response has been a growing effort to replace plastic items with alternative materials.  One very visible change of this sort has been the replacement of plastic cups with paper cups at coffee shops.  But a new study at the University of Gothenburg […]
