Published Rider on the storm: Shearwater seabird catches an 11 hour ride over 1,000 miles in a typhoon
(via sciencedaily.com) Original source New research suggests that increasingly severe weather driven by climate change may push oceangoing seabirds to their limits.
Published Report warns about risk tipping points with irreversible impacts on people and planet
(via sciencedaily.com) Original source A new report finds that drastic changes are approaching if risks to our fundamental socioecological systems are not addressed. The Interconnected Disaster Risks Report 2023 warns of six risk tipping points ahead of us: Accelerating extinctions; Groundwater depletion; Mountain glaciers melting; Space debris; Unbearable heat; and an Uninsurable future.
Published New study finds hidden trees across Europe: A billion tons of biomass is overlooked today
(via sciencedaily.com) Original source Through satellite imaging a new AI driven mapping of biomass and CO2 storage shows that a huge number of trees are overlooked in Europe's urban, rural, and agricultural areas. Across Europe, researchers have discovered a billion tons of hidden biomass.
Published Adapting to climate change: Individuals take action while governments plan
(via sciencedaily.com) Original source While governments may take the lead in planning and financing climate change adaptation measures, such as incentivizing green infrastructure, individuals currently are most often the ones implementing actions to adapt to climate change, according to new research.
Published Climate report: 'Uncharted territory' imperils life on Earth
(via sciencedaily.com) Original source An international coalition of climate scientists says that the Earth's vital signs have worsened beyond anything humans have yet seen, to the point that life on the planet is imperiled.
Published New study shows surprising effects of fire in North America's boreal forests
(via sciencedaily.com) Original source Using satellite images, researchers found that fires in North America's boreal forest may be changing the environment in ways that researchers didn't previously anticipate.
Published New extremes in stratospheric water vapor
(via sciencedaily.com) Original source The focus of new research was to determine how deep, how much and how frequently water in the stratosphere was being increased by thunderstorms.
Published Unearthing the ecological impacts of cicada emergences on North American forests
(via sciencedaily.com) Original source New research unveils the cascading effects of periodical cicada emergence events on forest ecosystems ahead of an historic convergence of broods set to emerge spring of 2024.
Published Scientists discover deepest known evidence of coral reef bleaching
(via sciencedaily.com) Original source Scientists have discovered the deepest known evidence of coral reef bleaching, more than 90 metres below the surface of the Indian Ocean. Identified during a research cruise, the damage to the deeper reefs in the Central Indian Ocean has been attributed to significant changes in the region's ocean temperature caused by the Indian Ocean Dipole. The researchers have also warned such incidences are only likely to increase as a result of present and future climate change.
Published New study finds 50-year trend in hurricane escalation linked to climate change
(via sciencedaily.com) Original source New research by climate scientists indicates that there have been great changes to Atlantic hurricanes in just the past 50 years, with storms developing and strengthening faster.
Published Yeast speeds discovery of medicinal compounds in plants
(via sciencedaily.com) Original source Researchers have harnessed the power of baker's yeast to create a cost-effective and highly efficient approach for unraveling how plants synthesize medicinal compounds, and used the new method to identify key enzymes in a kratom tree.
Published Study elucidates evolution of mosquitoes and their hosts
(via sciencedaily.com) Original source Study creates a mosquito family tree to better understand disease transmission and host choice.
Published Protecting polar bears: New and improved radar technology
(via sciencedaily.com) Original source Research testing new technology to more effectively locate polar bear dens across the Arctic is showing promising results. Researchers hope that improving detection tools to locate dens -- which are nearly invisible and buried under snow -- will help efforts to protect mother polar bears and their cubs.
Published As surging threats teeter electrical power grids, scientists offer insights to make them more resilient
(via sciencedaily.com) Original source Power grids -- the web of electrical networks that sprawl across countries and continents -- are under stress. Extreme weather events and volatile energy demands often push the system to the brink. Although these high-impact events can be very damaging, often overlooked is the impact of minor disruptions that trigger a domino effect throughout the system, according to a study analyzing European power blackouts. The findings showed that recovering power within 13 hours can reduce up to 52% of the power loss stemming from cascading events.
Published Subalpine forests in the Northern Rockies are fire resilient--for now
(via sciencedaily.com) Original source Using lake sediment cores, scientists determined how these subalpine ecosystems recovered after 4,800 years of fire.
Published Climate network analysis helps pinpoint regions at higher risk of extreme weather
(via sciencedaily.com) Original source Climate change and the rapid increase in frequency of extreme weather events around the globe reinforces the reality that these events are interconnected. Researchers now describe a climate network analysis method to explore the intensity, distribution, and evolution of this interlinked climate behavior, or teleconnections. The analysis combines the directions and distribution patterns of teleconnections to evaluate their intensity and to identify sensitive regions using global daily surface air temperature data. The method relies on advanced data processing and mathematical algorithms to find meaningful insights.
Published Rising seas will tighten vise on Miami even for people who are not flooded, says study
(via sciencedaily.com) Original source A new study that examines both the physical and socioeconomic effects of sea-level rise on Florida's Miami-Dade County area finds that in coming decades, four out of five residents may face disruption or displacement, whether they live in flood zones or not. As inundation spreads, the effects will be felt predominantly by lower-income people as habitable areas shrink and housing prices rise, says the study. Only a small number of affluent residents will be able relocate from low-lying or waterfront properties, while many others without sufficient means may be trapped there, it says.
Published New study confirms presence of flesh-eating and illness-causing bacteria in Florida's coastal waters following Hurricane Ian
(via sciencedaily.com) Original source When Hurricane Ian struck southwest Florida in September 2022, it unleashed a variety of Vibrio bacteria that can cause illness and death in humans, according to a new study.
Published Management zone maps of little use to corn growers
(via sciencedaily.com) Original source A multiyear analysis tested whether management zone maps based on soil conditions, topography or other landscape features can reliably predict which parts of a cornfield will respond best to higher rates of seeding or nitrogen application. The study found that -- contrary to common assumptions -- crop-plot responses to the same inputs vary significantly from year to year. The most unpredictable factor -- the weather -- seemed to have the biggest impact on how the crops responded to these inputs.
Published How weather phenomena affect ocean circulation
(via sciencedaily.com) Original source A new study has investigated how future changes in weather patterns could affect the tropical Pacific Ocean and its ecosystems. The research, based on complex computer models, has shown that these changes will have far-reaching consequences for ocean circulation. The authors stress the need to take this more into account in future climate models.
