The counting of nine billion trees could help manage climate credits and nature restoration      (via sciencedaily.com) 

Researchers have developed a method that has now mapped several billion trees and their carbon uptake in Africa's Sahel. In the future, the method could be used to monitor whether climate credit purchases have a positive effect on the number of trees and whether nature restoration is working.

Reassessment of Storegga event: Second major landslide recognized      (via sciencedaily.com) 

Submarine landslides have a large tsunami potential and occurred on the central Norwegian shelf more frequently in the past than previously thought. Scientists investigate the Nyegga landslide off the coast of Norway. The submarine landslide occurred in the same area as the well-known Storegga event 8,150 years ago. The new findings suggest that approximately one-third of the seafloor material missing -- previously attributed to the Storegga event -- was removed by the Nyegga event 20,000 years ago. This raises questions about the frequency of large submarine landslides and their associated tsunami hazard.

Seabirds in the eye of the storm      (via sciencedaily.com) 

Hurricanes are becoming more intense due to the climate crisis. Therefore, researchers have studied the wind speeds that different seabird species can withstand. The team was able to show that the individual species are well adapted to the average wind conditions in their breeding grounds, but use different strategies to avoid flying through the storm. Within their research, one behavior of the albatrosses particularly surprised the scientists.

How patterns emerge in salt deserts      (via sciencedaily.com) 

The honeycomb patterns which are often found in salt deserts in Death Valley, US, and Bolivia, among other places, look like something from another world. Researchers can now explain the origin of the mysterious patterns.

Estuaries face higher nutrient loads in the future -- particularly on the Atlantic coast      (via sciencedaily.com) 

A new study finds the Atlantic coast and eastern Gulf Coast of the United States are likely to see significant increases in nutrient loading in coming decades, putting those areas at heightened risk of experiencing harmful algal blooms.

Climate trends in the west, today and 11,000 years ago      (via sciencedaily.com) 

What we think of as the classic West Coast climate began just about 4,000 years ago, finds a study on climate trends of the Holocene era.

Sea urchin die-offs threaten Caribbean coral reefs      (via sciencedaily.com) 

The sustained loss of a once abundant species of sea urchin in the Caribbean could also result in the functional extinction of diverse coral species from the region's reefs, according to new research.

Human-wildlife conflicts rising worldwide with climate change      (via sciencedaily.com) 

Scientists reveal that a warming world is increasing human-wildlife conflicts globally. They show that climate shifts can drive conflicts by altering animal habitats, the timing of events, wildlife behaviors and resource availability. It also showed that people are changing their behaviors and locations in response to climate change in ways that increase conflicts.

Satellites observe speed-up of Glaciers on the Antarctic Peninsula      (via sciencedaily.com) 

Glaciers -- giant blocks of moving ice -- along Antarctica's coastline are flowing faster in the summer because of a combination of melting snow and warmer ocean waters, say researchers. On average, the glaciers travel at around one kilometre a year. But a new study has found a seasonal variation to the speed of the ice flow, which speeded up by up to 22 % in summer when temperatures are warmer. This gives an insight into the way climate change could affect the behaviour of glaciers and the role they could play in raising sea levels.

Clues about the Northeast's past and future climate from plant fossils      (via sciencedaily.com) 

A team of researchers is working to understand the details of the climate for the eastern portion of the United States from the Miocene, which unfortunately is a blank spot on paleo-climate maps. New findings suggest the future climate will be very close to the warmer, wetter, and more homogeneous climate similar to conditions experienced 5 million years ago.

Marine heatwaves decimate sea urchins, molluscs and more at Rottnest      (via sciencedaily.com) 

Researchers believe rising sea temperatures are to blame for the plummeting number of invertebrates such as molluscs and sea urchins at Rottnest Island off Western Australia, with some species having declined by up to 90 per cent between 2007 and 2021.

Researchers create E. coli-based water monitoring technology      (via sciencedaily.com) 

People often associate Escherichia coli with contaminated food, but E. coli has long been a workhorse in biotechnology. Scientists have now demonstrated that the bacterium has further value as part of a system to detect heavy metal contamination in water.

'Antisocial' damselfish are scaring off cleaner-fish customers -- and this could contribute to coral reef breakdown      (via sciencedaily.com) 

'Antisocial' damselfish are scaring off cleaner fish customers -- and this could contribute to coral reef breakdown. Damselfish have been discovered to disrupt 'cleaning services' vital to the health of reefs. And climate change may mean this is only likely to get worse.

Early Cretaceous shift in the global carbon cycle affected both land and sea      (via sciencedaily.com) 

Geologists doing fieldwork in southeastern Utah's Cedar Mountain Formation found carbon isotope evidence that the site, though on land, experienced the same early Cretaceous carbon-cycle change recorded in marine sedimentary rocks in Europe. This ancient carbon-cycle phenomenon, known as the 'Weissert Event' was driven by large, sustained volcanic eruptions in the Southern Hemisphere that greatly increased carbon dioxide levels in the atmosphere and produced significant greenhouse climate effects over a prolonged time.

As sea ice declines in the Arctic, bowhead whales are adjusting their migration patterns      (via sciencedaily.com) 

As sea ice declines in the Arctic, bowhead whales are staying north of the Bering Strait more frequently, a shift that could affect the long-term health of the bowhead population and impact the Indigenous communities that rely on the whales, a new study shows.
