The warmer, greener Arctic and greenhouse gas

Earth Wise ·

2025/04/16

About 15% of the Northern Hemisphere is covered by permafrost. Permafrost is soil and sediment that has remained frozen for long periods of time, in some cases as much as 700,000 years. It contains large amounts of dead biomass that has accumulated over millennia and hasn’t fully decomposed. Therefore, permafrost is an immense carbon sink. […]

Microplastics are a real problem. They are pretty much everywhere. They are in our food, in the oceans, on mountains, up in the clouds, and most alarmingly, in our bodies. All of that is already bad news, but researchers at Boston University have found that microplastics may also be contributing to antibiotic resistance in dangerous […]

Microplastics are small plastic pieces less than five millimeters long and typically far smaller than that. They come from a variety of sources, often from larger plastic debris that degrades into smaller and smaller pieces. There are also microbeads, which are tiny pieces of manufactured polyethylene plastic that are added to various health and beauty […]

Climate risks for apple-growing areas

Earth Wise ·

2025/01/31

The changing climate is creating challenges for some of the most productive apple growing regions in America. A study by Washington State University analyzed over 40 years of climate conditions that impact the growth cycle of apple trees. Many growing areas face increased climate risk, but the top three apple-producing counties are among the most […]

The battle over wolves

Earth Wise ·

2025/01/10

Thirty years ago, wolves were reintroduced into Yellowstone National Park. Grey wolves had almost disappeared entirely throughout the northern Rockies. They were listed as endangered by the federal government since 1974. The reintroduction was hailed as a wildly successful effort yielding significant benefits to Yellowstone’s ecosystems. Since then, wolf populations have increased greatly across the […]

Earth Wise ·

2024/11/01

The frequent and massive megafires in places like Canada and the American west have led to a lot of research on the impact of smoke on humans but there has been less study of the effects of smoke on plant health. Researchers at the University of California, Davis have found that trees are just as […]

The Earth’s atmosphere contains enormous amounts of water. Being able to efficiently and economically extract some of it to provide drinking water would be extremely beneficial to the billions of people across the globe who face chronic water shortages. There are existing technologies for atmospheric water harvesting – or AWH. But there are downsides associated […]

Much more energy storage for New York

Earth Wise ·

2024/08/02

As solar and wind power play an ever-growing role in the electricity grid, the need for energy storage also grows. Even if sun and wind can provide more energy than is needed at a particular time, they can’t provide it at all times. The ability to store excess energy waiting in reserve for when the […]
