A recent study by Kayrros and French Climate and Environmental Science Laboratory (LSCE) provides the first statistical characterization of methane ultra-emitters from oil and gas activities. The study detects approximately 1,800 ultra-emitters, which account for a significant portion of global methane emissions.
A new analysis predicts climate change will decline suitable regions for coffee arabica, cashews, and avocados in major producing countries. Suitable areas may expand at higher altitudes and latitudes, particularly for cashews and avocados.
Researchers at the University of Helsinki and VTT Technical Research Centre of Finland have developed a biotechnology-based solution to produce ovalbumin, a key protein in egg white powder. The fungus-produced ovalbumin reduces greenhouse gas emissions and land use by up to 72% compared to traditional chicken-based production.
A recent study published in Methods in Ecology and Evolution found that local environmental knowledge is a valuable tool for conservation in the Amazon, comparable to other scientific methods. Local ecological knowledge proved to be more accurate than 10 years of conventional scientific monitoring for animal abundance in the Amazon.
A new analysis found that non-vegetarian diets result in higher greenhouse gas emissions than vegetarian diets, while a diet rich in nutrients and low in saturated fats can significantly reduce emissions. The study suggests small changes, such as cutting out sweets or switching brands, can make big environmental gains.
A study by Technical University of Munich found that major tech companies significantly underreported CO2 emissions from their value chain, with 50% of emissions omitted in 2019. The researchers developed a method to identify reporting gaps and estimated the omitted emissions at 751 megatons carbon dioxide equivalents.
A life cycle assessment of carbon capture at Amager Bakke incineration plant reveals that the technology reduces CO2 emissions from incineration but decreases electricity production by 50%. The overall net energy efficiency is not affected, but heat output increases by 20%.
A study quantifying Nigeria-linked seizures of pangolin products suggests levels of trafficking are far greater than previously thought. Researchers found 190,407 kilos of scales taken from at least 799,343 animals, with 77 seizures analysed revealing connections to ivory-smuggling networks.
Damaged coral reefs exhibit a two-phase recovery pattern, with the first phase lasting up to six years, and the second phase being faster. This pattern was observed in 60% of severely disturbed reefs on the Great Barrier Reef.
Satellite images reveal a substantial increase in saltmarsh area and stable trends of tidal flat areas after 2012, driven by decreased anthropogenic activities and increased conservation and restoration efforts. Conservation efforts have positively impacted China's coastal wetlands, mitigating the loss of these important ecosystems.
Researchers have compiled a dataset of microplastic abundance in the world's upper oceans, estimating 24.4 trillion pieces weighing 82,000-578,000 tons. The data fills gaps in global coverage and provides realistic amounts for assessing impact on aquatic organisms.
Researchers applied a physics method to Balinese rice irrigation practices, finding that a balance between water stress and pest stress is crucial for equilibrium. The traditional method, which involves synchronized flooding, can help maintain social harmony and prevent chaos in water schedules.
A study found that seabirds around the globe consume up to 52% of plastic, leading to accumulation of its chemical components in their bodies. Researchers analyzed oil from preen glands and stomach contents of bird carcasses to determine contaminant burdens.
Researchers found socio-cultural barriers, lack of maintenance and funding, economic challenges, institutional barriers, technological and environmental barriers hinder GI adoption. Community-based approach identified the need for increased transparency and communication from government, as well as resident participation and engagement.
A new study from the University of California, Santa Cruz, develops a comprehensive framework to determine when short-term changes in behavior caused by human activities have biological significance. The framework highlights the importance of life history traits and specific characteristics of disturbances in assessing vulnerability.
A new study found that global marine ecosystem models differ widely in their representation of key processes, leading to underestimation of climate change impacts. Marine ecosystem models generally agree on biomass decline but disagree on magnitude and location across the world's oceans through the 21st century.
The Stoffenmanager and Advanced REACH Tool models have significant deficiencies in their use, affecting chemical safety assessments. The models are based on subjective parameter values and lack physical principles, leading to uncertainty in exposure values.
A team of University of Wisconsin-Madison researchers investigated mining-related deforestation in the Peruvian Amazon to see if formalizing and legalizing these operations could reduce their negative effects. The study found that while formalization has potential, it needs enforcement and regulations to match the local context.
Researchers found that reusable plastic bags are the most eco-friendly option, followed by single-use plastic bags, due to their lower environmental footprint compared to single-use paper and multi-use cotton bags. Reusable plastic bags can be reused over 50 times before becoming environmentally detrimental.
A new study developed a better method for evaluating fabric softeners that could lead to potentially "greener" and more millennial-friendly versions. The researchers found that the concentration of surfactant affected vesicle size and arrangement, which could help manufacturers assess efficiency and speed up design.
