Published New method to analyze implications of large-scale flood adaptation
(via sciencedaily.com)
Original source 
In a test of their new analysis tool, researchers show where 'moving up' or 'moving over' may make the most sense for those affected by the 2022 Pakistan flood, and what costs it would entail.
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 Bizarre new fossils shed light on ancient plankton
(via sciencedaily.com)
Original source 
Recently discovered microfossils date back half a billion years. Resembling modern-day algae, they provide insight into early life in our oceans.
Published Bitcoin mining has 'very worrying' impacts on land and water, not only carbon
(via sciencedaily.com)
Original source 
As bitcoin and other cryptocurrencies have grown in market share, they've been criticized for their heavy carbon footprint: Cryptocurrency mining is an energy-intensive endeavor. Mining has massive water and land footprints as well, according to a new study that is the first to detail country-by-country environmental impacts of bitcoin mining.
Published Raining cats and dogs: Global precipitation patterns a driver for animal diversity
(via sciencedaily.com)
Original source 
A team has identified several factors to help answer a fundamental ecological question: why is there a ridiculous abundance of species some places on earth and a scarcity in others? What factors, exactly, drive animal diversity? They discovered that what an animal eats (and how that interacts with climate) shapes Earth's diversity.
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 Light, freshwater sticks to Greenland's east coast
(via sciencedaily.com)
Original source 
Meltwater that runs along the east coast of Greenland, hardly enters the open ocean before reaching the western side of the island. In the changing climate, fresh water from Greenland and the Arctic could disrupt the circulation in the Atlantic Ocean.
Published Increased West Antarctic Ice Sheet melting 'unavoidable'
(via sciencedaily.com)
Original source 
The West Antarctic Ice Sheet will continue to increase its rate of melting over the rest of the century, no matter how much we reduce fossil fuel use, according to new research. A substantial acceleration in ice melting likely cannot now be avoided, which implies that Antarctica's contribution to sea level rise could increase rapidly over the coming decades.
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 Soil carried on sea freight loaded with dangerous pests and diseases, research finds
(via sciencedaily.com)
Original source 
While sea freight is recognised as a pathway for the movement of exotic organisms, there is little research that has quantified the risk. Soil collected from the external surfaces of sea freight was found to support live microorganisms, worms, seeds and insects, including various regulated biosecurity organisms. The research confirms that shipping containers provide a pathway for the movement of exotic species.
Published El Niño's changing patterns: Human influence on natural variability
(via sciencedaily.com)
Original source 
Two recent scientific studies provide new insights into Earth's climate dynamics, with a particular focus on the El Niño phenomenon. The results show how El Niño responds to natural factors over extended periods, while highlighting the increasing role of human activities in shaping this climatic phenomenon in the modern era.
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 Urgent action needed to address climate change threats to coastal areas
(via sciencedaily.com)
Original source 
Global coastal adaptations are 'incremental in scale', short-sighted and inadequate to address the root causes of vulnerability to climate change, according to an international team of researchers.
Published Ancient diamonds shine light on the evolution of Earth
(via sciencedaily.com)
Original source 
Formed millions to billions of years ago, diamonds can shine light into the darkest and oldest parts of the Earth's mantle. The analysis of ancient, superdeep diamonds dug up from mines in Brazil and Western Africa, has exposed new processes of how continents evolved and moved during the early evolution of complex life on Earth. These diamonds that were formed between 650 and 450 million years ago on the base of the supercontinent Gondwana, were analysed by an international team of experts, and have shown how supercontinents such as Gondwana were formed, stabilised, and how they move around the planet.
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 Ocean circulation, ice melt and increasing tourism could all be contributing to Arctic microplastics
(via sciencedaily.com)
Original source 
Scientists measured microplastic concentrations in the highly productive Barents Sea and suggest that ocean circulation, ice melt, tourism, inadequate waste management, shipping and fishing are all likely contributors.
Published World may have crossed solar power 'tipping point'
(via sciencedaily.com)
Original source 
The world may have crossed a 'tipping point' that will inevitably make solar power our main source of energy, new research suggests.
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 Unique marimo threatened by rising lake temperatures
(via sciencedaily.com)
Original source 
Rising lake water temperatures threaten the survival of marimo, unique algal balls found only in cold lakes. Researchers clarified that the warmer it gets, the more the inward decomposition outpaces the outward growth of these life forms, making them increasingly fragile.
