Purified fly ash used to produce greener, stronger concrete
March 29, 2023The production of the cement is a major source of greenhouse gas emissions, which is why some people have tried replacing it with fly ash. A new technique makes that fly ash more eco-friendly, resulting in concrete which is greener and stronger. -
Protecting and restoring wildlife offers a new climate solution
March 28, 2023A new study has found that sea and land wildlife are the "missing link" between biodiversity and climate. By protecting and restoring wildlife we can enhance natural carbon capture mechanisms and reduce climate change. -
Widening of "doomsday glacier's" main ice stream would accelerate ice loss
March 27, 2023A new study by Stanford University suggests that an 80-mile-wide (130-km) stream of ice in the heart of Antarctica's "doomsday glacier" may expand over the next 20 years, which would increase its ice loss and contribute to sea level rises. -
Antarctic snowfalls found to affect short-term sea level rises
March 23, 2023Based on a 25-year record of the Western Antarctic Ice Sheet, a team of scientists led by the British Antarctic Survey (BAS) have shown that changes in snowfall over Antarctica can have significant short-term effects on global sea level rises. -
Wood-derived powder could remove dye from textile industry wastewater
March 23, 2023In countries such as India, a great deal of toxic dye waste from the textile industry is released into waterways, harming people and the environment. A new wood-derived filtration media could remove much of that dye from wastewater streams. -
Latest IPCC report on climate change: "More ambitious action" needed
March 20, 2023The IPCC has released its latest report, pulling together the findings of previous reports to provide a more complete picture of how human-caused climate change continues to affect the planet and what we need to do to address it. -
Underwater turbulence revealed as a key factor in climate change
March 19, 2023Much of the heat and carbon produced by humans is absorbed by the ocean. New research has shed light on the role that underwater waves play in moving that heat and carbon around our oceans, an important factor in predicting climate change. -
Australia is using an imported insect to control an imported weed
March 08, 2023What do you do if a South American weed is choking up your local Australian waterways? In the case of the cabomba plant, scientists are enlisting the help of the weed's natural South American enemy, the tiny cabomba weevil. -
Semi-transparent solar cells boost growth of greenhouse plants
March 07, 2023Solar farms and agriculture are competing for land. UCLA Scientists have now tested a way to combine the two by placing semi-transparent solar cells on the glass roofs of greenhouses, finding that they actually improve the growth of plants inside. -
Study suggests a mix of trees works best for cleaning air in cities
March 07, 2023We all know that trees help clean the air in cities, but which trees do so best? According to new research conducted in Sweden, a mixture of deciduous and coniferous trees will give you the most bang for your buck. -
Non-soggy biodegradable drinking straws made from wood waste
March 06, 2023Although disposable plastic straws are being phased out, their "greener" replacements have a few shortcomings of their own. Well, scientists have now developed bioplastic straws that don't get soggy, but do biodegrade when discarded. -
Historic world agreement commits to protecting international waters
March 05, 2023After nearly 20 years of negotiations, 193 nations have come together to draft the High Seas Treaty, an agreement that will set the world on track to protect 30% of international waters, fund marine conservation and better regulate sea-bed mining. -
Paleo and keto diets bad for health and the planet, says study
March 02, 2023The health benefits of a meat-based versus a plant-based diet are often hotly debated. A new study adds another checkmark to the plant-based column though, as it loops in the environmental impacts of choosing paleo or keto diets over veganism. -
World-first aquaculture operation will raise salmon and kelp together
February 28, 2023Although salmon farms help take pressure off wild stocks, the penned fish do produce a lot of waste which is concentrated at one location. A new farm is exploring a solution to that problem, by raising salmon and kelp in adjacent pens. -
Andes microbial tech uses farmers' fields to capture greenhouse gases
February 27, 2023While crops do sequester some atmospheric carbon dioxide (CO2) via photosynthesis, they could always use a bit of help. California startup Andes is aiming to provide that help, by putting carbon-capturing microbes in the soil of farmers' fields.
