Published Evolution might stop humans from solving climate change
(via sciencedaily.com) Original source Human culture has evolved to allow humans to extract resources and helped us expand to dominate the biosphere. But the same evolutionary processes may counteract efforts to solve new global environmental threats like climate change, according to a new study. Tackling the climate crisis will require worldwide regulatory, technical and economic systems supported by strong global cooperation. However, this new study concludes that the group-level processes characteristic of human cultural evolution, will cause environmental competition and conflict between sub-global groups, and work against global solutions. Adapting to climate change and other environmental problems will, therefore, require human evolution to change.
Published Understanding climate mobilities: New study examines perspectives from South Florida practitioners
(via sciencedaily.com) Original source A recent study assessed the perspectives of 76 diverse South Florida climate adaptation professionals. A new study explores the expectations and concerns of practitioners from the private sector, community-based organizations, and government agencies about the region's ability to adapt in the face of increasing sea level rise and diverse consequences for where people live and move, also known as climate mobility.
Published Reducing inequality is essential in tackling climate crisis, researchers argue
(via sciencedaily.com) Original source Promoting climate-friendly behaviors will be more successful in societies where everyone has the capacity: financially, physically, and time-wise, to make changes.
Published 'Nutritional quality must be at the heart of climate smart agriculture' -- researchers
(via sciencedaily.com) Original source Farmers in sub-Saharan Africa need to diversify away from growing maize and switch to crops that are resilient to climate change and supply enough key micronutrients for the population, according to a major research study. Maize is a staple crop across the region -- where it is grown and consumed in vast quantities.
Published Global warming intensifies typhoon-induced extreme precipitation over East Asia
(via sciencedaily.com) Original source Scientists use a 3km high-resolution climate model to reveal expanded extreme rainfall from typhoons.
Published Unraveling the mysteries of fog in complex terrain
(via sciencedaily.com) Original source While fog presents a major hazard to transportation safety, meteorologists have yet to figure out how to forecast it with the precision they have achieved for precipitation, wind and other stormy events. This is because the physical processes resulting in fog formation are extremely complex, Now researchers report their findings from an intensive study centered on a northern Utah basin and conceived to investigate the life cycle of cold fog in mountain valleys.
Published In coastal communities, sea level rise may leave some isolated
(via sciencedaily.com) Original source Amid the threat of dramatic sea level rise, coastal communities face unprecedented dangers, but a new study reveals that as flooding intensifies, disadvantaged populations will be the ones to experience some of the most severe burdens of climate change.
Published Revolutionary nanodrones enable targeted cancer treatment
(via sciencedaily.com) Original source A research team has unveiled a remarkable breakthrough in cancer treatment.
Published How technology and economics can help save endangered species
(via sciencedaily.com) Original source A lot has changed in the world since the Endangered Species Act (ESA) was enacted 50 years ago in December 1973. Experts are now discuss how the ESA has evolved and what its future might hold.
Published Novel catalyst system for CO2 conversion
(via sciencedaily.com) Original source Researchers are constantly pushing the limits of technology by breaking new ground in CO2 conversion. Their goal is to turn the harmful greenhouse gas into a valuable resource. A novel catalyst system could help reach that goal.
Published How national policies affect forests in border regions
(via sciencedaily.com) Original source How do national policies impact deforestation? Researchers have looked into this question at the global scale and have found that, contrary to common assumptions, national strategies have a significant -- and visible -- influence on efforts to protect forest heritage.
Published Tree plantations can get better with age -- but original habitats are best
(via sciencedaily.com) Original source Older tree plantations can be more attractive to animals who are looking for a new home than younger plantations, according to a new study. In the tropics, older plantations also welcome a greater variety of different plants and animals -- though sadly, Christmas tree plantations do not become more biodiverse over time.
Published Finding new ways to adapt to a growing weather threat
(via sciencedaily.com) Original source Research reveals a steady increase in the number of people at risk from tropical cyclones and the number of days per year these potentially catastrophic storms threaten health and livelihoods. The findings could help relief agencies, development banks, and other organizations plan more effective strategies for mitigating extreme weather impacts.
Published Scientists uncover link between the ocean's weather and global climate
(via sciencedaily.com) Original source Scientists outline the first direct evidence linking seemingly random weather systems in the ocean with climate on a global scale. The team's work creates a promising framework for better understanding the climate system.
Published Multitasking microbes: Scientists engineer bacteria to make two valuable products from plant fiber
(via sciencedaily.com) Original source Researchers have engineered bacteria that can produce two chemical products at the same time from underutilized plant fiber. And unlike humans, these multitasking microbes can do both things equally well. The discovery could help make biofuels more sustainable and commercially viable.
Published Reduced air pollution during pandemic points to way to preserve Himalayan glaciers
(via sciencedaily.com) Original source Reducing air pollution to levels similar to those during the coronavirus pandemic could protect the glaciers in the Himalayas and prevent them from disappearing by the end of the century. This is the conclusion reached by an international research team analyzing the situation during the COVID-19 lockdown in 2020.
Published Scientists provide recipe to halve pollution from food production
(via sciencedaily.com) Original source A major report has put forward solutions to halve nitrogen pollution from agriculture and the food system in Europe, including reducing meat and dairy consumption, fertilizer use and food waste. Inefficiencies in farms, retail and wastewater practices mean that the nitrogen use efficiency of the food system in Europe is only 18%, leaving most of the remainder leaking into air, water and soils. The new report, Appetite for Change, has been produced by a group of researchers coordinated by the UK Centre for Ecology & Hydrology (UKCEH), the European Commission, Copenhagen Business School and the National Institute for Public Health and the Environment (RIVM) of The Netherlands.
Published Artificial intelligence unravels mysteries of polycrystalline materials
(via sciencedaily.com) Original source Researchers have used artificial intelligence to solve a difficult problem in crystal science. Seeking to understand why crystals develop tiny defects called dislocations, the researchers discovered unique defects that look like staircases. This discovery helps to better understand the defects in crystals that reduce the efficiency of complex polycrystalline materials used in our everyday electronic devices.
Published Low economic growth can help keep climate change within the 1.5 °C threshold
(via sciencedaily.com) Original source A new study shows that economic growth rates make a big difference when it comes to prospects for limiting global warming to 1.5 °C, as per the Paris Agreement. A recent study shows that pursuing higher economic growth may jeopardize the Paris goals and leave no viable pathways for humanity to stabilize the climate. On the contrary, slower growth rates make it more feasible to achieve the Paris goals.
