Published Mixed approach to reforestation better than planting or regeneration alone
(via sciencedaily.com) Original source Reforestation in low- and middle-income countries can remove up to 10 times more carbon dioxide from the atmosphere at lower cost than previously estimated, making it a potentially more effective option to fight climate change. Most current reforestation programs focus on tree planting alone, but the study estimates that nearly half of all suitable reforestation locations would be more effective at sequestering carbon if forests were allowed to grow back naturally.
Published Warehousing industry increases health-harming pollutants, research shows
(via sciencedaily.com) Original source A new study shows an average 20-percent spike of nitrogen dioxide polluting the air for communities located near huge warehouses. And people of color are harder hit.
Published Traffic-related ultrafine particles hinder mitochondrial functions in olfactory mucosa
(via sciencedaily.com) Original source Ultrafine particles, UFPs, the smallest contributors to air pollution, hinder the function of mitochondria in human olfactory mucosa cells, a new study shows. The study showed that traffic-related UFPs impair mitochondrial functions in primary human olfactory mucosa cells by hampering oxidative phosphorylation and redox balance.
Published Trees reveal climate surprise -- bark removes methane from the atmosphere
(via sciencedaily.com) Original source Tree bark surfaces play an important role in removing methane gas from the atmosphere.
Published Drawing water from dry air
(via sciencedaily.com) Original source A prototype device harvests drinking water from the atmosphere, even in arid places.
Published Manufacturing perovskite solar panels with a long-term vision
(via sciencedaily.com) Original source Researchers working at the forefront of an emerging photovoltaic (PV) technology are thinking ahead about how to scale, deploy, and design future solar panels to be easily recyclable. Solar panels made of perovskites may eventually play an important role amid global decarbonization efforts to reduce greenhouse gas emissions. As the technology emerges from the testing stages, it is a perfect time to think critically about how best to design the solar panels to minimize their impact on the environment decades from now.
Published Researchers develop more environmentally friendly and cost-effective method for soil remediation
(via sciencedaily.com) Original source Chemists have developed a rapid electrothermal mineralization (REM) process, which in seconds can remediate the accumulation of synthetic chemicals that can contaminate soil and the environment.
Published Researchers warn of unprecedented arsenic release from wildfires
(via sciencedaily.com) Original source The wildfire season of 2023 was the most destructive ever recorded in Canada and a new study suggests the impact was unprecedented. It found that four of the year's wildfires in mine-impacted areas around Yellowknife, Northwest Territories potentially contributed up to half of the arsenic that wildfires emit globally each year.
Published Best bioenergy crops for sustainable aviation fuels by U.S. region, policy goals
(via sciencedaily.com) Original source Researchers analyzed the financial and environmental costs and benefits of four biofuels crops used to produce sustainable aviation fuels in the U.S. They found that each feedstock -- corn stover, energy sorghum, miscanthus or switchgrass -- performed best in a specific region of the rainfed United States. Their study will help growers and policymakers select the feedstocks most suited to meeting goals like reducing production costs, lowering greenhouse gas emissions and building soil carbon stocks.
Published A window of opportunity for climate change and biodiversity
(via sciencedaily.com) Original source World leaders must take advantage of a pivotal window of opportunity for forging a much-needed joined-up approach to tackle climate change and biodiversity loss, say scientists. Without this, work on tackling either crisis could inadvertently harm progress on the other.
Published Heat-sensitive trees move uphill seeking climate change respite
(via sciencedaily.com) Original source Trees in the Brazilian Atlantic Forest are migrating in search of more favourable temperatures with species in mountain forests moving uphill to escape rising heat caused by climate change.
Published Strategic emission caps key to ammonia industry decarbonization, researchers find
(via sciencedaily.com) Original source New research has revealed critical insights into how strategic emission cap choices can lead to cost-effective, near-100% ammonia industry decarbonization while avoiding issues such as land use constraints and grid congestion.
Published Hot traces in rock
(via sciencedaily.com) Original source Fluids circulating underground change rocks over the course of time. These processes must be taken into account if they are to be used as a climate archive. Researchers have used 380-million-year-old limestones from Hagen-Hohenlimburg to show in detail which climate information is still preserved in the rock.
Published Children's exposome associated with changes in serum metabolites
(via sciencedaily.com) Original source The combined effect of environmental exposures and unhealthy lifestyle habits can affect children's cardiometabolic health in a way that exceeds their separate effects. A new study shows the benefit of measuring the combined effect of multiple environmental and lifestyle factors.
Published A promising new method uses light to clean up forever chemicals
(via sciencedaily.com) Original source A room-temperature method to decompose perfluoroalkyl substances (PFASs) using visible LED light offers a promising solution for sustainable fluorine recycling and PFAS treatment.
Published Using forest resources strengthens food security
(via sciencedaily.com) Original source Forests can reduce hunger in rural households while also capturing carbon and advancing sustainability goals for low- and middle-income countries, according to new research.
Published Tropical plant species are as threatened by climate change as widely feared, study confirms
(via sciencedaily.com) Original source Biologists who set out to better understand the effects of climate change on plant species in tropical mountain regions found that even small variations in temperature and moisture can have massive impacts, threatening not only plants that live there, but also the ecosystems they support. A study based on labor-intensive fieldwork and analysis in tropical mountain regions shows that a warmer and drier climate will lead to massive losses of plant species.
Published Researchers enhance tool to better predict where and when wildfires will occur
(via sciencedaily.com) Original source A newly enhanced database is expected to help wildfire managers and scientists better predict where and when wildfires may occur by incorporating hundreds of additional factors that impact the ignition and spread of fire.
Published Converting captured carbon to fuel: Study assesses what's practical and what's not
(via sciencedaily.com) Original source A new analysis sheds light on major shortfalls of a recently proposed approach to capture CO2 from air and directly convert it to fuel using electricity. The authors also provide a new, more sustainable, alternative.
Published Ecologists discover rare fiddler crab species on Hong Kong coast highlighting the impact of climate change and coastal development
(via sciencedaily.com) Original source Researchers have made an exciting discovery on the Hong Kong coast. They have identified two fiddler crab species: Tubuca dussumieri, previously recorded in old literature but never confirmed in recent times, and Tubuca. coarctata, which has never been seen in Hong Kong. These findings not only confirm the presence of these insular species in Hong Kong but also explore the potential impact of climate change on their distribution.
