US ocean observation critical to understanding climate change, but lacks long-term national planning
Fri, 20 Oct 2017 12:57:58 EDT
Ocean observing systems are important as they provide information essential for monitoring and forecasting changes in Earth's climate on timescales ranging from days to centuries. A new report finds that continuity of ocean observations is vital to gain an accurate understanding of the climate, and calls for a decadal, national plan that is adequately resourced and implemented to ensure critical ocean information is available to understand and predict future changes.

Life goes on for marine ecosystems after cataclysmic mass extinction
Fri, 20 Oct 2017 09:22:26 EDT
One of the largest global mass extinctions did not fundamentally change marine ecosystems, scientists have found.
Cool roofs have water saving benefits too
Fri, 20 Oct 2017 09:22:13 EDT
The energy and climate benefits of cool roofs have been well established: By reflecting rather than absorbing the sun's energy, light-colored roofs keep buildings, cities, and even the entire planet cooler. Now a new study has found that cool roofs can also save water by reducing how much is needed for urban irrigation.
Declining baby songbirds need forests to survive drought

A new study aimed to identify characteristics that promote healthy wood thrush populations on US Department of Defense land.
Scientists see order in complex patterns of river deltas
Thu, 19 Oct 2017 10:10:21 EDT
River deltas, with their intricate networks of waterways, coastal barrier islands, wetlands and estuaries, often appear to have been formed by random processes, but scientists see order in the apparent chaos.
Rare tree species safeguard biodiversity in a changing climate

Rare species of trees in rainforests may help safeguard biodiversity levels as the environment undergoes change, research shows.
New light shed on early turquoise mining in Southwest
Wed, 18 Oct 2017 15:18:24 EDT
Researchers are blending archaeology and geochemistry to get a more complete picture of turquoise's mining and distribution in the pre-Hispanic Southwest.
Illinois sportfish recovery a result of 1972 Clean Water Act, scientists report
Wed, 18 Oct 2017 12:17:06 EDT
Populations of largemouth bass, bluegill, catfish and other sportfish are at the highest levels recorded in more than a century in the Illinois River, according to a new report. Their dramatic recovery, from populations close to zero near Chicago throughout much of the 20th century, began just after implementation of the Clean Water Act, the researchers say.
DNA tests on albatross excrement reveal secret diet of top predator
Wed, 18 Oct 2017 11:35:48 EDT
A study that used DNA tests to analyse the scats of one of the world's most numerous albatrosses has revealed surprising results about the top predator's diet. DNA analysis of 1460 scats from breeding sites around the Southern Ocean has shown that the diet of black-browed albatrosses contains a much higher proportion of jellyfish than previously thought.
Hardy corals make their moves to build new reefs from scratch
Wed, 18 Oct 2017 11:35:40 EDT
Resilient species of coral can move to inhospitable areas and lay the foundations for new reefs, a study shows.
Life in the city: Living near a forest keeps your amygdala healthier
Wed, 18 Oct 2017 11:35:15 EDT
A new study examined the relationship between the availability of nature near city dwellers' homes and their brain health. Its findings are relevant for urban planners among others.
Reducing power plants' freshwater consumption with new silica filter
Wed, 18 Oct 2017 11:35:06 EDT
Power plants draw more freshwater than any other consumer in the United States, accounting for more than 50 percent of the nation's freshwater use at about 500 billion gallons daily. To help save this water, researchers have developed a new silica filter for power plant cooling waters that decreases the amount of freshwater power plants consume by increasing the number of times cooling tower water can be reused and recycled.
The puzzle to plugging the worst natural gas release in history
Wed, 18 Oct 2017 09:16:42 EDT
By the time scientists visited the Aliso Canyon natural gas storage facility in December 2015, the SS-25 well blowout had been leaking natural gas into the air for more than six weeks. The notoriously strong winds at Aliso Canyon carried the natural gas and its added odorant to the nearby Porter Ranch neighborhood, leading to thousands of families evacuating their homes.
New Amazon threat? Deforestation from mining
Wed, 18 Oct 2017 09:02:12 EDT
Sprawling mining operations in Brazil have caused roughly 10 percent of all Amazon rainforest deforestation between 2005 and 2015 -- much higher than previous estimates -- says the first comprehensive study of mining deforestation in the iconic tropical rainforest. Surprisingly, the majority of mining deforestation (a full 90%) occurred outside the mining leases granted by Brazil's government, the new study finds.
Nice ice, maybe: Study finds water-repelling surfaces ease ice removal
Wed, 18 Oct 2017 08:56:56 EDT
A new study has discovered that ice grows differently on water-absorbent vs. water-repellent surfaces. The research suggests that applying water-repellent coatings to windshields before winter storms -- or engineering surfaces that inherently repel water -- could enable a strong breeze to handle the burden of ice removal.
Chocolate production linked to increased deforestation in poor nations
Tue, 17 Oct 2017 16:36:22 EDT
Newly published research focuses on the link between cocoa exports and deforestation in developing nations.
Amazonian hunters deplete wildlife but don't empty forests
Tue, 17 Oct 2017 15:31:48 EDT
Conservationists can be 'cautiously optimistic' about the prospect of sustainable subsistence hunting by Amazonian communities, according to new research. The research team spent over a year working with 60 Amazonian communities and hiked for miles through trackless forests to deploy nearly 400 motion-activated camera traps -- in a bid to understand which species are depleted by hunting and where.
Fighting fires before they spark
Tue, 17 Oct 2017 15:29:44 EDT
With warm, dry summers comes a deadly caveat for the western United States: wildfires. Scientists say the hot, dry climates found west of the Mississippi, along with decades of fire suppression efforts, are creating a devastating and destructive combination -- leading to fires like the ones currently burning in California. Now, new research is giving forest and fire management teams across the country the upper hand in reducing the severity of these events.
Study reshapes understanding of climate change's impact on early societies
Tue, 17 Oct 2017 12:43:35 EDT
A new study linking paleoclimatology -- the reconstruction of past global climates -- with historical analysis shows a link between environmental stress and its impact on the economy, political stability, and war-fighting capacity of ancient Egypt.
