Dams could play a big role in feeding the world more sustainably

“There is an urgent need to explore alternative water storage solutions, but we have to acknowledge that many dams are already in place,” said study lead author Rafael Schmitt, a research engineer with the Stanford Natural Capital Project. “Our research illuminates their crucial role in ensuring food security in the future.” Typical agricultural practices in …

Uterine fibroid growth activated by phthalates, chemicals found in everyday products

Manufacturers use environmental phthalates in numerous industrial and consumer products, and they’ve also been detected in medical supplies and food. , they are currently unbanned in the U.S. “These toxic pollutants are everywhere, including food packaging, hair and makeup products, and more, and their usage is not banned,” said corresponding study author Dr. Serdar Bulun, …

Climate change strikes: Lightning patterns change with global warming

This could lead to more lightning over mountains and in Northern Europe and less lightning over central Europe. The Newcastle University and Met Office-led study, published in the journal Environmental Research Letters, finds there could be a picture of changing weather patterns including: More frequent storms with more energy, but locally less lightning mainly due …

Using monsoons of the past to predict climate conditions of the future

Subtropical regions like southwestern North America are becoming drier in response to global warming, as higher temperatures cause more aridity overall. However, rising temperatures can also lead to instances of excess precipitation during the summer months. The mechanism driving this is a strengthening monsoon. Just this past summer, southern California felt the effects of the …

New technology creates carbon neutral chemicals out of thin air

The technology could allow scientists to both capture CO2 and transform it into useful chemicals such as carbon monoxide and synthetic natural gas in one circular process. Dr Melis Duyar, Senior Lecturer of Chemical Engineering at the University of Surrey commented: “Capturing CO2 from the surrounding air and directly converting it into useful products is …

The world will probably warm beyond the 1. 5-degree limit, but peak warming can be curbed

But countries can curb time spent in a warmer world by adopting more ambitious climate pledges and decarbonizing faster, according to new research led by scientists at the Department of Energy’s Pacific Northwest National Laboratory, the University of Maryland and the U.S. Environmental Protection Agency. Doing so, they warn, is the only way to minimize …

Low levels of air pollution deadlier than previously thought

“We found that outdoor PM2.5 may be responsible for as many as 1.5 million additional deaths around the globe each year because of effects at very-low concentrations that were not previously appreciated,” said Scott Weichenthal, an Associate Professor in the Department of Epidemiology, Biostatistics, and Occupational Health at McGill University and the lead author on …

Earth-sun distance dramatically alters seasons in the equatorial Pacific in a 22,000-year cycle

But new computer simulations show that one driver of annual weather cycles in that region — in particular, a cold tongue of surface waters stretching westward along the equator from the coast of South America — has gone unrecognized: the changing distance between Earth and the sun. The cold tongue, in turn, influences the El …
