Large atmospheric waves in the jet stream present risk to global food production
Mon, 09 Dec 2019 11:21:47 EST
Researchers have discovered jet stream patterns that could affect up to a quarter of global food production.
Dramatic health benefits following air pollution reduction
Fri, 06 Dec 2019 17:36:34 EST
Reductions in air pollution yielded fast and dramatic impacts on health-outcomes, as well as decreases in all-cause morbidity, according to new findings.
As China rapidly adopts clean energy, use of traditional stoves persists
Thu, 05 Dec 2019 15:53:19 EST
Old habits are hard to break. A new study of replacement of traditional wood and coal burning stoves with clean energy in China suggests that, without a better understanding of the reasons behind people's reluctance to give up traditional stoves, it will be difficult for policies in China and elsewhere in the world to succeed in encouraging this shift towards clean energy.
A solution for cleaning up PFAS, one of the world's most intractable pollutants
Thu, 05 Dec 2019 13:06:02 EST
Engineers have developed a treatment train for a PFAS compound called HFPO-Dimer Acid, also known by its trade name, GenX.
Prenatal and early life exposure to multiple air pollutants increases odds of toddler allergies
Thu, 05 Dec 2019 13:05:54 EST
A new article shows a significant association between multiple prenatal and early life exposures to indoor pollutants and the degree of allergic sensitivity in 2-year-olds.
Microwave treatment is an inexpensive way to clean heavy metals from treated sewage
Thu, 05 Dec 2019 13:05:32 EST
A team of researchers studying new methods to remove toxic heavy metals from biosolids -- the solid waste left over after sewage treatment -- found the key is a brief spin through a microwave.
Less rice, more nutritious crops will enhance India's food supply
Wed, 04 Dec 2019 17:04:00 EST
India can sustainably enhance its food supply if its farmers plant less rice and more nutritious and environmentally-friendly crops, including finger millet, pearl millet, and sorghum, according to a new study.
Atmospheric river storms create $1 billion-a-year flood damage
Wed, 04 Dec 2019 15:28:42 EST
Researchers found that flooding has caused nearly $51 billion in damages to western states in the last 40 years. More than 84 percent of these damages were caused by atmospheric rivers (ARs), long narrow corridors of water vapor in the atmosphere capable of carrying more than twice the volume of the Amazon river through the sky.
Outlook for the polar regions in a 2-degrees-warmer world
Wed, 04 Dec 2019 14:49:14 EST
With 2019 on pace as one of the warmest years on record, a major new study reveals how rapidly the Arctic is warming and examines global consequences of continued polar warming. The study reports that the Arctic has warmed by 0.75 degrees C in the last decade alone.
Looking at tropical forests through new eyes
Wed, 04 Dec 2019 14:49:08 EST
Air-based maps of plant chemistry are improving carbon cycling models in hyper-diverse tropical forests.
Global carbon emissions growth slows, but hits record high
Wed, 04 Dec 2019 09:08:31 EST
Coal use is down dramatically in the United States and the European Union, and renewable energy is gaining traction. But rising natural gas and oil use in 2019 increased the world's carbon dioxide emissions modestly for a third straight year.
Smog-eating graphene composite reduces atmospheric pollution
Tue, 03 Dec 2019 10:47:59 EST
A graphene-titania photocatalyst degrades up to 70% more atmospheric NOx than standard titania nanoparticles in tests on real pollutants.
How to improve water quality in Europe
Tue, 03 Dec 2019 10:20:36 EST
Toxic substances from agriculture, industry and households endanger water quality in Europe -- and by extension, ecosystems and human health. As part of the SOLUTIONS project, over 100 international scientists have developed methods and practical solutions for identifying pollutants and assessing the risks posed by chemical cocktails. This is intended to help reduce pollution in water resources. Researchers have described how politicians can implement these scientific results in 15 policy briefs.
Mystery of how early animals survived ice age
Mon, 02 Dec 2019 19:04:23 EST
How did life survive the most severe ice age? A team has found the first direct evidence that glacial meltwater provided a crucial lifeline to eukaryotes during Snowball Earth, when the oceans were cut off from life-giving oxygen, answering a question puzzling scientists for years.
Tiny woodlands are more important than previously thought
Mon, 02 Dec 2019 12:46:28 EST
Small woodlands in farmland have more benefits for humans per area, compared to large forests according to a new study. The small woodlands, sometimes even smaller than a football field, can easily go unnoticed in agricultural landscapes. Yet, these small forest remnants can store more carbon in the topsoil layer, are more suitable for hunting activities and host fewer ticks than large forests.
