Relatively few, massive lakes hold an incredible majority of the world’s fresh water. These lakes are scattered all over the globe, meaning the relationship between humans and the fresh water nearest them varies by

Heavy rains throughout the mid-Atlantic during 2018 and early 2019 led to high runoff into the Chesapeake Bay. Credit: © D. Malmquist/VIMS. An annual model-based report on “dead-zone” conditions in the Chesapeake Bay during 2019 indicates the total volume of low-oxygen, “hypoxic” water was on the high end of the normal range for 1985 to

Air pollution doesn’t just come from cars on the road, generating electricity from fossil fuels also releases fine particulate matter into the air. In general, fine particulate matter can lead to heart attacks, strokes, lung cancer and other diseases, and is responsible for more than 100,000 deaths each year in the United States. Now University

Integrating a super moisture-absorbent gel with light-active materials, researchers in Singapore have developed a humidity digester to dry the ambient air while generating energy. The method, presented November 20 in the journal Joule, is a green alternative to air conditioners with a trick — pulling water out of thin air. Like plants, artificial photosynthetic devices,

The harmful algae bloom slimes fishing boats, paints beaches in toxins and engulfs water intake cribs. In 2014, it left

How serious are airlines about cutting emissions? Airlines have taken steps to reduce their carbon footprints under the gaze of public opinion, but the pressure of the bottom line means some fly with extra fuel, boosting emissions of climate-changing greenhouse gases. As the highly competitive air travel industry is being pushed to reduce its carbon

The study was published in the peer-reviewed academic journal Africa Today. It was co-authored by Francis Owusu, professor

Lakes and ponds are the final resting place for many of the Earth’s plants. Rivers collect much of the planet’s dead organic matter, transporting it to rest in calmer waters. But on a microscopic scale, lakes are anything but calm. An invisible metropolis of microbes feeds on these logs and leaves, producing greenhouse gases as

Electricity supply is one of the biggest CO2 emitters globally. To keep global warming well below 2°C, several paths lead to zero emissions in the energy sector, and each has its potential environmental impacts — such as air and water pollution, land-use or water demand. Using a first-time combination of multiple modelling systems, an international
