An Expert Discusses the True Impact of Microplastics on Human Health

It’s well-known that enjoying a tasty fish fillet or a seafood platter provides essential nutrients like omega-3s and vitamin D. However, these meals often come with an unwelcome side: numerous micro- and nano-plastics. Plastic particles smaller than 5 millimeters find their way into oceans through human waste, infiltrating the food chain. An Ifremer study estimates […]

Air Fryers Found to Be the Least Polluting Cooking Method

Air fryers emit significantly less indoor air pollution than other cooking methods, such as pan and deep frying, according to a new study. While cooking is a major source of indoor air pollution, much of the research has focused on air fryers’ energy efficiency, leaving their environmental benefits less explored. Since most people spend over

Fossil Fuel CO2 Emissions Rise Once More in 2024

Climatology, Earth Science, Environmental Science / Mauro Lucas

Global carbon emissions from fossil fuels hit a record high in 2024, according to the latest research from the Global Carbon Project. Fossil CO2 emissions are projected to reach 37.4 billion tonnes, a 0.8% increase from 2023. Despite the urgent need to cut emissions to combat climate change, researchers say there is no sign yet

Oceans release more sulfur and cool the climate more than expected.

Earth Science, Environmental Science / Eduardo Paulo

Researchers have, for the first time, measured global emissions of a sulfur gas from marine life, showing it cools the climate more than previously believed, particularly over the Southern Ocean. A study published in Science Advances reveals that oceans not only absorb and redistribute solar heat but also emit gases that create particles with immediate

Is There Enough Land to Fight Climate Change and Feed the World?

Earth Science, Environmental Science, Science / Ngoma Manuel

Limiting global warming to 1.5°C is a challenging task. Reaching this target will require not only a significant reduction in greenhouse gas emissions from human activities but also a major reorganization of land use to support these efforts and maintain the biosphere, including human populations. More land will be necessary to meet the rising demand

Previously Unknown Chemical Discovered in Drinking Water

Earth Science, Environmental Science / Mauro Lucas

Drinking water in developed countries is generally clean, yet invisible contaminants can still pose risks. For decades, scientists have puzzled over a mysterious “phantom chemical” in treated water. Now, researchers have identified this elusive compound, revealing it as entirely new to science. The Mystery of Chloramine By-Products Chlorination is a common method for disinfecting drinking

Solar Still Made of Old Tires Purifies Water at Less Than 1c/Liter

Earth Science, Environmental Science / Eduardo Paulo

Canadian scientists have developed an innovative device that can purify a gallon of water per day for just a few cents. Even better, this sustainable purifier is made from recycled tires and can also generate small amounts of electricity. Innovative Solar Still Turns Undrinkable Water into Safe Drinking Water While Earth has abundant water, much

Dark Oxygen Discovered in the Ocean: What Does It Mean?

Earth Science, Environmental Science / Valeriano Ndeyi

Plants, whether in the ocean or on land, largely produce the oxygen essential for intelligent life as we know it through photosynthesis of carbon dioxide. However, new research suggests that depths with no light might generate oxygen without relying on living organisms. The authors of the study, published in Nature Geoscience, collected samples of marine

Greenhouse Gas Concentrations Reach Record Levels as Scientists Raise Concerns

Earth Science, Environmental Science / Ngoma Manuel

In 2023, greenhouse gas concentrations in the atmosphere hit new record highs, ensuring future temperature rises for years ahead, the United Nations cautioned on Monday. The levels of the three primary greenhouse gases—carbon dioxide, methane, and nitrous oxide, which contribute to climate warming—have all risen once more over the past year, according to the UN’s
