How ice particles promote the formation of radicals
Fri, 07 Dec 2018 11:27:46 EST
The production of chlorofluorocarbons, which damage the ozone layer, has been banned as far as possible. However, other substances can also tear holes in the ozone layer in combination with ice particles, such as those found in clouds. Researchers have discovered a possible mechanism for this.
New algorithm provides a more detailed look at urban heat islands
Fri, 07 Dec 2018 11:26:41 EST
Urban areas are warmer than the adjacent undeveloped land, a phenomenon known as the urban heat island effect. A new interactive map gives us the most detailed look yet at these 'urban heat islands' across the world.
Rules to boost fuel economy for passenger vehicles will do more good than harm, new study shows
Thu, 06 Dec 2018 14:12:20 EST
Experts conclude that rules on the books to increase fuel economy for passenger vehicles will do more good than harm, contradicting claims by the Trump administration as it seeks to roll back fuel economy standards.
Fighting smog supports solar power
Thu, 06 Dec 2018 11:59:40 EST
Model calculations by researchers show that if China fought smog more aggressively, it could massively increase solar power production.
Transforming our food system to ensure a sustainable future
Thu, 06 Dec 2018 11:47:29 EST
By 2050, the world will have almost 10 billion people. It will be impossible to feed everyone without exacerbating poverty, accelarting deforestation and increasing GHG emissions unless we start making substantial changes to our food system now. This issue is covered in a new report.
Industrial fisheries are starving seabirds all around the world
Thu, 06 Dec 2018 11:47:26 EST
Industrial fisheries are starving seabirds like penguins and terns by competing for the same prey sources. Seabirds are now the most threatened bird group.
Report reveals link between air pollution and increased risk for miscarriage
Wed, 05 Dec 2018 15:22:06 EST
Researchers found women living along the Wasatch Front -- the most populous region in the state of Utah -- had a higher risk (16 percent) of miscarriage following short-term exposure to elevated air pollution.
Dirty air now could harm hearts of offspring later
Wed, 05 Dec 2018 13:40:09 EST
A parent's exposure to dirty air before conception might spell heart trouble for the next generation, a new animal study suggests.
Pollution: New ammonia emission sources detected from space
Wed, 05 Dec 2018 13:39:48 EST
Researchers have prepared the first global map of the distribution of atmospheric ammonia (NH3) by analyzing measurements taken by satellites between 2008 and 2016. The IASI interferometer allowed them to catalog more than 200 ammonia sources, two-thirds of which had never been identified before. These sources are essentially sites of intensive livestock production and industrial activity.
Greenland ice sheet melt 'off the charts' compared with past four centuries
Wed, 05 Dec 2018 13:39:42 EST
Surface melting across Greenland's mile-thick ice sheet began increasing in the mid-19th century and then ramped up dramatically during the 20th and early 21st centuries, showing no signs of abating, according to new research.
Flint, Michigan lead crisis should have buried the city in water bottles. So, why didn't it?
Wed, 05 Dec 2018 09:38:09 EST
The Flint, Michigan lead crisis should have buried the city in waste. A case study investigates why not and proposes solutions for future water disasters.
Neighborhoods with more green space may mean less heart disease
Wed, 05 Dec 2018 09:37:18 EST
People who live in neighborhoods with more green spaces may have better blood vessel health and lower levels of stress, and a lower risk of cardiovascular diseases such as heart attacks, strokes and others.
How mussels handle microplastic fiber pollution
Tue, 04 Dec 2018 13:11:27 EST
New research shows that mussels readily take in microplastic pollution fibers from the ocean but quickly flush most of them out again, according to a new study.
Salt-evolved zooplankton grow too slowly to block salt-induced algal blooms
Mon, 03 Dec 2018 08:16:56 EST
Small animals at the base of the freshwater food chain can rapidly adapt to salt pollution -- from sources like winter road deicing, agriculture, and mining -- but at a price.
Saltier waterways are creating dangerous 'chemical cocktails'
Mon, 03 Dec 2018 08:03:24 EST
New research suggests that saltier, more alkaline freshwater can release toxic metals and harmful nitrogen-containing compounds from streambeds and soils in drainage basins. The results further suggest that many of these chemicals travel together throughout watersheds, forming 'chemical cocktails' that can have more devastating effects on drinking water supplies and ecosystems when compared with individual contaminants alone.
