Published Effect of aerosol particles on clouds and the climate captured better



Global measurements and model calculations show that the complex relationship between the chemistry and climate impact of aerosol particles can be successfully captured by a simple formula.
Published AI finds formula on how to predict monster waves



Using 700 years' worth of wave data from more than a billion waves, scientists have used artificial intelligence to find a formula for how to predict the occurrence of these maritime monsters. Long considered myth, freakishly large rogue waves are very real and can split apart ships and even damage oil rigs.
Published Protect delicate polar ecosystems by mapping biodiversity



Concerted action is required to mitigate the impact of warming on polar ecosystems and sustainably manage these unique habitats.
Published Massive 2022 eruption reduced ozone layer levels



The Hunga Tonga-Hunga Ha'apai volcano changed the chemistry and dynamics of the stratosphere in the year following the eruption, leading to unprecedented losses in the ozone layer of up to 7% over large areas of the Southern Hemisphere.
Published Coastal river deltas threatened by more than climate change



Worldwide, coastal river deltas are home to more than half a billion people, supporting fisheries, agriculture, cities, and fertile ecosystems. In a unique study covering 49 deltas globally, researchers have identified the most critical risks to deltas in the future. The research shows that deltas face multiple risks, and that population growth and poor environmental governance might pose bigger threats than climate change to the sustainability of Asian and African deltas, in particular.
Published Deep dive on sea level rise: New modelling gives better predictions on Antarctic ice sheet melt



Using historical records from around Australia, an international team of researchers have put forward the most accurate prediction to date of past Antarctic ice sheet melt, providing a more realistic forecast of future sea level rise. The Antarctic ice sheet is the largest block of ice on earth, containing over 30 million cubic kilometers of water. Hence, its melting could have a devasting impact on future sea levels. To find out just how big that impact might be, the research team turned to the past.
Published Scientists have solved the damselfly color mystery



For over 20 years, a research team has studied the common bluetail damselfly. Females occur in three different color forms -- one with a male-like appearance, something that protects them from mating harassment. In a new study, an international research team found that this genetic color variation that is shared between several species arose through changes in a specific genomic region at least five million years ago.
Published Nature photographers posting to social media help with protecting biodiversity



Nature photographers posting to social media are helping improve biodiversity conservation mapping in South Asia, and the method could go global.
Published Research in Lake Superior reveals how sulfur might have cycled in Earth's ancient oceans



A scientists has sulfur on her mind. The yellow element is a vital macronutrient, and she's trying to understand how it cycles through the environment. Specifically, she's curious about the sulfur cycle in Earth's ancient ocean, some 3 billion years ago.
Published New global stocktake: Healthy forests could store much more carbon



Natural carbon reservoirs will play a major role at the COP28 world climate conference in the United Arab Emirates. In a recent study, a team of more than two hundred researchers worldwide presents new estimates of the storage potential of forests around the globe. According to the study, forests could ideally absorb 328 billion tons (gigatons, Gt for short) of carbon. However, as many formerly forested areas are now used for agriculture and as settlement areas, the potential is reduced to 226 Gt. 139 Gt of this (61%) could be achieved by protecting existing forests alone. The remaining 87 Gt (39%) could be realized by reconnecting previously fragmented forest landscapes and managing them sustainably.
Published New study reveals huge potential for future waves of invasive species



Human trade and transport have led to the intentional and accidental introductions of non-native species outside of their natural range globally. These biological invasions can cause extinctions, cost trillions, and spread diseases. A study has investigated how many of these non-native species already exist worldwide and which species groups are particularly prone to become non-native.
Published WhaleVis turns more than a century of whaling data into an interactive map



A team has created an interactive dashboard called WhaleVis, which lets users map data on global whale catches and whaling routes from 1880 to 1986. Scientists can compare this historical data and its trends with current information to better understand whale populations over time.
Published Reforms needed to expand prescribed burns



A new paper pinpoints obstacles and suggests strategies for getting more prescribed fire on the ground in the wildfire-prone U.S. West.
Published Climate change effects hit marine ecosystems in multiple waves, according to marine ecologists



A new approach to examining the effects of climate change on marine ecosystems may provide a more accurate understanding of climate change responses -- and predictions for future consequences -- according to a new article. The paper highlights the interplay between the trend of climate warming and the fluctuations in local temperature. These two properties cause atypically warm events such as marine heatwaves to occur with increasing frequency and magnitude.
Published Ice cores from Earth's highest tropical peak provide insight into climate variability



A new study examines ice cores from the summit of the highest tropical mountain in the world, and finds unique insight into the climate record of the Amazon Basin over the last six decades.
Published Clearing mangroves makes 'muddification' worse



Clearing mangroves to stop estuaries getting clogged with mud actually makes the problem worse, new research shows.
Published Climate engineering could slow Antarctic ice loss, study suggests



A study reports that scattering sunlight-reflecting particles in the atmosphere -- a theoretical form of climate engineering known as 'stratospheric aerosol injection' -- has potential to slow rapid ice melt in Western Antarctica.
Published Roaming seabirds need ocean-wide protection



Seabirds roam far and wide in the Indian Ocean -- so they need ocean-wide protection, new research shows.
Published Previously unknown luminescence revealed in ten deep sea species and an order of sea cucumbers



Researchers present evidence of previously unknown luminosity in 10 deep-sea species, suggesting underestimated diversity. These new discoveries include a member of the order Molpadia, which was previously thought not to be luminescent. The authors stress the importance of considering the ecological role of bioluminesence and the need for conservation.
Published Melting ice falling snow: Sea ice declines enhance snowfall over West Antarctica



As the world continues to warm, Antarctica is losing ice at an increasing pace, but the loss of sea ice may lead to more snowfall over the ice sheets, partially offsetting contributions to sea level rise.
