Methane hydrate is not a smoking gun in the Arctic Ocean
Tue, 22 Aug 2017 10:04:00 EDT
Methane hydrate under the ocean floor was assumed to be very sensitive to increasing ocean temperatures. But a new study shows that short term warming of the Arctic ocean barely affects it.
Dino-killing asteroid could have thrust Earth into two years of darkness
Mon, 21 Aug 2017 15:10:56 EDT
Tremendous amounts of soot, lofted into the air from global wildfires following a massive asteroid strike 66 million years ago, would have plunged Earth into darkness for nearly two years, new research finds. This would have shut down photosynthesis, drastically cooled the planet, and contributed to the mass extinction that marked the end of the age of dinosaurs.
Study validates East Antarctic ice sheet to remain stable even if western ice sheet melts
Thu, 17 Aug 2017 16:20:28 EDT
A new study validates that the central core of the East Antarctic ice sheet should remain stable even if the West Antarctic ice sheet melts.
Discovery could lead to new catalyst design to reduce nitrogen oxides in diesel exhaust
Thu, 17 Aug 2017 14:17:25 EDT
Researchers have discovered a new reaction mechanism that could be used to improve catalyst designs for pollution control systems to further reduce emissions of smog-causing nitrogen oxides in diesel exhaust.
Whales turn tail at ocean mining noise
Thu, 17 Aug 2017 11:08:55 EDT
A new international study has measured the effect of loud sounds on migrating humpback whales as concern grows as oceans become noisier. Scientists have said one of the main sources of ocean noise was oil and gas exploration, due to geologists firing off loud acoustic air guns to probe the structure of the ocean floor in search of fossil fuels.
Measuring global biodiversity change
Thu, 17 Aug 2017 09:32:02 EDT
A new article shows how Essential Biodiversity Variables can be produced to measure biodiversity change at a global scale.
Heavily-used pesticide linked to breathing problems in farmworkers' children
Wed, 16 Aug 2017 14:32:59 EDT
New study finds that elemental sulfur is linked to reduced lung function, more asthma-related symptoms and higher asthma medication use in children living about a half-mile or less from farms that use the pesticide.
Greenland ice flow likely to speed up
Wed, 16 Aug 2017 14:18:46 EDT
Flow of the Greenland Ice Sheet is likely to speed up in the future, despite a recent slowdown, because its outlet glaciers slide over wet sediment, not hard rock, new research based on seismic surveys has confirmed. This sediment will become weaker and more slippery as global temperatures rise and meltwater supply becomes more variable. The findings challenge the view that the recent slowdowns in ice flow would continue in the long term.
Mystery of how first animals appeared on Earth solved
Wed, 16 Aug 2017 13:47:27 EDT
Research has solved the mystery of how the first animals appeared on Earth, a pivotal moment for the planet without which humans would not exist.
Air pollution linked to cardiovascular disease; air purifiers may lessen impact
Mon, 14 Aug 2017 16:19:58 EDT
Exposure to fine particulate matter via air pollution, led to increases in stress hormones and, in a study of healthy college students in China. Negative effects of pollution exposure decreased after using indoor air purifiers over a nine-day period.
Tiny fraction of oceans could meet world's fish demand
Mon, 14 Aug 2017 12:53:40 EDT
Covering 70 percent of Earth's surface, the world's oceans are vast and deep. So vast, in fact, that nearly every coastal country has the potential to meet its own domestic seafood needs through aquaculture. In fact, each country could do so using a tiny fraction of its ocean territory.
Urban floods intensifying, countryside drying up
Mon, 14 Aug 2017 09:29:41 EDT
Drier soils and reduced water flow in rural areas -- but more intense rainfall that overwhelms infrastructure and causes flooding and stormwater overflow in urban centers. That's the finding of an exhaustive study of the world's river systems, based on data collected from more than 43,000 rainfall stations and 5,300 river monitoring sites across 160 countries.
Canary in a coal mine: Survey captures global picture of air pollution's effects on birds
Fri, 11 Aug 2017 12:48:13 EDT
Writing Aug. 11 in the journal Environmental Research Letters, University of Wisconsin-Madison Professor Tracey Holloway, an expert on air quality, and her former graduate student Olivia Sanderfoot sort through nearly 70 years of the scientific literature to assess the state of knowledge of how air pollution directly affects the health, well-being, reproductive success and diversity of birds.
Crank the AC, cut in-car pollution
Thu, 10 Aug 2017 14:17:33 EDT
After conducting a new research approach using actual commutes, a group of engineers discovered a simple shift in driving habits can help to reduce exposure to pollutants while out on the road.
