Published Climate change to push species over abrupt tipping points
(via sciencedaily.com) Original source Climate change is likely to abruptly push species over tipping points as their geographic ranges reach unforeseen temperatures, finds a new study.
Published Automated window shades show potential for significant energy savings
(via sciencedaily.com) Original source Automated insulating window shades can cut energy consumption by approximately one-quarter and may recoup the cost of installation within three to five years, according to a landmark study. The study showcases a promising path for sustainability and energy efficiency in architectural design.
Published Study finds carrying pollen heats up bumble bees, raises new climate change questions
(via sciencedaily.com) Original source A new study finds carrying pollen is a workout that significantly increases the body temperature of bumble bees. This new understanding of active bumble bee body temperatures raises questions about how these species will be impacted by a warmer world due to climate change.
Published Assessing emotions in wild animals
(via sciencedaily.com) Original source A new study examines indicators of mental wellbeing in wild animals to improve conservation efforts.
Published Extremely hot days are warming twice as fast as average summer days in North-West Europe
(via sciencedaily.com) Original source New study analyzed data on near-surface air temperatures recorded for North-West Europe over the past 60 years. The findings show that the maximum temperature of the hottest days is increasing at twice the rate of the maximum temperature of average summer days. The results highlight the need for urgent action by policy makers to adapt essential infrastructure to the impacts of climate change.
Published Butterflies on the decline
(via sciencedaily.com) Original source Research shows that the numbers of butterflies in meadows and pastures of Europe are in a continuous decline. Grassland butterflies will soon play an even greater role in EU nature conservation legislation. Based on the occurrences and population trends of butterflies, the member states are supposed to document the progress they have made in implementing the planned 'Nature Restoration Law'.
Published Chemical exposure may raise your risk for Parkinson's
(via sciencedaily.com) Original source Two years of heavy exposure to TCE, a liquid chemical that lingers in the air, water and soil, may increase the risk of Parkinson's disease by 70%.
Published African smoke over the Amazon
(via sciencedaily.com) Original source Up to two-thirds of the soot above the central Amazon rainforest originates in Africa. Researchers differentiate soot particles using their relative properties and attribute them to their respective points of origin. They found that bush fires and burning savannah in the north and south of Africa make a substantial contribution to air pollution in the central Amazon all year round, thereby playing an important role in the earth radiation budget and water cycle. This is caused by the efficient transatlantic transport of particles through the atmosphere.
Published About 13,000 years ago, the water outflow from the Mediterranean to the Atlantic Ocean was twice that of today’s
(via sciencedaily.com) Original source About 13,000 years ago, a climate crisis caused a global drop in temperatures in the northern hemisphere. This episode of intense cold, known as the Younger Dryas, also caused severe aridity across the Mediterranean basin, which had a major impact on terrestrial and marine ecosystems. But what do we know about the impact of this climate change on water circulation in the Mediterranean?
Published 'Warm Ice Age' changed climate cycles
(via sciencedaily.com) Original source Approximately 700,000 years ago, a 'warm ice age' permanently changed the climate cycles on Earth. During this exceptionally warm and moist period, the polar glaciers greatly expanded. A research team identified this seemingly paradoxical connection. The shift in the Earth's climate represents a critical step in our planet's later climate development.
Published Scientists reveal breakthrough that could lead to cleaner hydrogen energy
(via sciencedaily.com) Original source Chemists have taken a big step toward splitting hydrogen and oxygen molecules to make pure hydrogen -- without using fossil fuels. Results from pulse radiolysis experiments have laid bare the complete reaction mechanism for an important group of 'water-splitting' catalysts. The work means scientists are closer to making pure hydrogen from renewable energy, an energy source that could contribute to a greener future for the nation and world.
Published We now know exactly what happens in nature when we fell forests
(via sciencedaily.com) Original source Deforestation is the biggest threat to the planet's ecosystems, and new research has now mapped out exactly what happens when agriculture replaces forestry.
Published Porous crystals made from plant extracts purify water from pharmaceutical pollutants
(via sciencedaily.com) Original source Researchers have developed porous crystals made from pomegranate extract to capture and degrade pharmaceutical molecules found in local municipal wastewater.
Published With formic acid towards CO2 neutrality
(via sciencedaily.com) Original source Researchers develop a new method for the sustainable use of carbon dioxide.
Published Land use linked to water quality and quantity
(via sciencedaily.com) Original source Researchers recently published a study that focuses on the Sudbury-Assabet and Concord watershed in eastern Massachusetts, and which links hydrological changes, including floods, drought and runoff, to changing patterns of land use.
Published Metal-filtering sponge removes lead from water
(via sciencedaily.com) Original source Engineers have developed a new sponge that can remove metals -- including toxic heavy metals like lead and critical metals like cobalt -- from contaminated water, leaving safe, drinkable water behind. In proof-of-concept experiments, the researchers tested their new sponge on a highly contaminated sample of tap water, containing more than 1 part per million of lead. With one use, the sponge filtered lead to below detectable levels.
Published 'Improved' cookstoves emit more ultrafine particles than conventional stoves
(via sciencedaily.com) Original source Improved cookstoves, which are widely used for cooking in developing countries, produce twice as many harmful ultrafine air pollution particles (PM0.1) as conventional stoves, according to a new study.
Published Great Basin: History of water supply in one of the driest regions in the USA
(via sciencedaily.com) Original source An international team has reconstructed the evolution of groundwater in the Great Basin, USA -- one of the driest regions on Earth -- up to 350,000 years into the past with unprecedented accuracy. The results shed new light on the effects of climate change on water supply and provide important insights for the sustainable use of groundwater resources.
Published Global warming puts whales in the Southern Ocean on a diet
(via sciencedaily.com) Original source In the autumn, when right whales swim towards the coasts of South Africa, they ought to be fat and stuffed full. But in recent years, they have become thinner because their food is disappearing with the melting sea ice.
Published Bacteria: Radioactive elements replace essential rare earth metals
(via sciencedaily.com) Original source Bacteria can use certain radioactive elements to sustain their metabolism.
