Global study of coastal seas as carbon dioxide reservoirs      (via sciencedaily.com)     Original source 

Coastal seas form a complex transition zone between the two largest CO2 sinks in the global carbon cycle: land and ocean. Ocean researchers have now succeeded for the first time in investigating the role of the coastal ocean in a seamless model representation.

Greener streets linked to better sleep      (via sciencedaily.com)     Original source 

Living on a greener street or having views of blue spaces from your home may help you sleep for longer. New research across 18 countries found that living on greener streets -- those with visible grass, trees, and vegetation -- is linked to better sleep.

Persian plateau unveiled as crucial hub for early human migration out of Africa      (via sciencedaily.com)     Original source 

A new study combining genetic, palaeoecological, and archaeological evidence has unveiled the Persian Plateau as a pivotal geographic location serving as a hub for Homo sapiens during the early stages of their migration out of Africa. It highlights the period between 70,000 to 45,000 years ago when human populations did not uniformly spread across Eurasia, leaving a gap in our understanding of their whereabouts during this time frame.

Better phosphorus use can ensure its stocks last more than 500 years and boost global food production      (via sciencedaily.com)     Original source 

More efficient use of phosphorus could see limited stocks of the important fertilizer last more than 500 years and boost global food production to feed growing populations. But these benefits will only happen if countries are less wasteful with how they use phosphorus, a study shows. Around 30-40 per cent of farm soils have over-applications of phosphorus, with European and North American countries over-applying the most.

Droughts in Europe could be avoided with faster emissions cuts      (via sciencedaily.com)     Original source 

Models suggest summer rainfall in southern Europe could decline by up to 48% by the year 2100 if emissions of greenhouse gases continue to rise rapidly.

Scientists explore complex pattern of tipping points in the Atlantic's current system      (via sciencedaily.com)     Original source 

New mathematical modeling of the Atlantic meridional overturning circulation -- a system of ocean currents -- shows greater complexity than previously thought. Researchers have revealed a hierarchy of irreversible 'tipping points.'

Enormous ice loss from Greenland glacier      (via sciencedaily.com)     Original source 

Ground-based measuring devices and aircraft radar operated in the far northeast of Greenland show how much ice the 79 N-Glacier is losing. According to recent measurements, the thickness of the glacier has decreased by more than 160 meters since 1998. Warm ocean water flowing under the glacier tongue is melting the ice from below. High air temperatures cause lakes to form on the surface, whose water flows through huge channels in the ice into the ocean. One channel reached a height of 500 meters, while the ice above was only 190 meters thick.

New geological study: Scandinavia was born in Greenland      (via sciencedaily.com)     Original source 

The oldest Scandinavian bedrock was 'born' in Greenland, according to a new geological study. The study helps us understand the origin of continents and why Earth is the only planet in our solar system with life.

A new way to quantify climate change impacts: 'Outdoor days'      (via sciencedaily.com)     Original source 

'Outdoor days,' a new measure, describes climate change impacts by noting the number of days per year that outdoor temperatures are comfortable enough for normal outdoor activities.

Satellite data assimilation improves forecasts of severe weather      (via sciencedaily.com)     Original source 

In 2020, a line of severe thunderstorms unleashed powerful winds that caused billions in damages across the Midwest United States. A new technique that incorporates satellite data could improve forecasts -- including where the most powerful winds will occur -- for similar severe weather events.

Forest, stream habitats keep energy exchanges in balance, global team finds      (via sciencedaily.com)     Original source 

Forests and streams are separate but linked ecosystems, existing side by side, with energy and nutrients crossing their porous borders and flowing back and forth between them. For example, leaves fall from trees, enter streams, decay and feed aquatic insects. Those insects emerge from the waters and are eaten by birds and bats. An international team has now found that these ecosystems appear to keep the energy exchanges in balance -- a finding that the scientists called surprising.

Deep Earth electrical grid mystery solved      (via sciencedaily.com)     Original source 

To 'breathe' in an environment without oxygen, bacteria in the ground beneath our feet depend upon a single family of proteins to transfer excess electrons, produced during the 'burning' of nutrients, to electric hairs called nanowires projecting from their surface.

Researchers investigate how freshwater diatoms stay in the light      (via sciencedaily.com)     Original source 

Researchers sought to understand how diatoms -- microscopic, photosynthetic algae that make up an estimated 20 percent of global carbon sequestration and oxygen production -- are able to bloom in an ice-covered Lake Erie and how ice decline across the Great Lakes is impacting the algae.

Fish fed to farmed salmon should be part of our diet, too, study suggests      (via sciencedaily.com)     Original source 

Scientists found that farmed salmon production leads to an overall loss of essential dietary nutrients. They say that eating more wild 'feed' species directly could benefit our health while reducing aquaculture demand for finite marine resources.

From the Mediterranean into the Atlantic: The Gibraltar arc is migrating to the west      (via sciencedaily.com)     Original source 

Oceans are subject to continuous change, mostly over extremely vast periods of time running into millions of years. Researchers have now used computer simulations to demonstrate that a subduction zone originating in the Western Mediterranean will propagate into the Atlantic under the Strait of Gibraltar. According to their model, this will create a new Atlantic subduction zone 50 million years into the future, which will then move down into the Earth's mantle. The new geodynamic model explains the evolution of the Gibraltar subduction zone and its likely development, which will contribute to the renewal of the Atlantic Ocean floor.

There are large accumulations of plastics in the ocean, even outside so-called garbage patch      (via sciencedaily.com)     Original source 

When plastic ends up in the ocean, it gradually weathers and disintegrates into small particles. If marine animals ingest these particles, their health can be severely affected. Large accumulations of plastic can therefore disrupt the biological balance of marine ecosystems. But which areas are particularly affected?

Fish species that move rapidly toward the poles due to global warming decline in abundance, study finds      (via sciencedaily.com)     Original source 

A new study has found a decline in the abundance of marine fish species that move rapidly toward the poles to escape rising sea temperatures. The researchers explain that many animal species are currently moving toward cooler regions as a result of global warming, but the velocity of such range shifts varies greatly for different species. Examining thousands of populations from almost 150 fish species, the researchers show that contrary to the prevailing view, rapid range shifts coincide with widescale population declines.

Virtual reality better than video for evoking fear, spurring climate action      (via sciencedaily.com)     Original source 

Depicting worst-case climate scenarios like expanding deserts and dying coral reefs may better motivate people to support environmental policies when delivered via virtual reality, according to a research team that studied how VR and message framing affect the impact of environmental advocacy communications. The study findings may help advocacy groups decide how best to frame and deliver their messages.
