Acidity of Antarctic waters could double by century's end, threatening biodiversity      (via sciencedaily.com)     Original source 

Without drastically reducing global emissions, the Antarctic Ocean could become too acidic for hundreds of species living there, many already endangered by rising temperatures and sea ice loss.

Green ammonia could decarbonize 60% of global shipping when offered at just 10 regional fuel ports      (via sciencedaily.com)     Original source 

A study has found that green ammonia could be used to fulfill the fuel demands of over 60% of global shipping by targeting just the top 10 regional fuel ports. Researchers looked at the production costs of ammonia which are similar to very low sulphur fuels, and concluded that the fuel could be a viable option to help decarbonize international shipping by 2050.

Is natural spa water a fossil of water? Uncover the real ultra-deep water cycles      (via sciencedaily.com)     Original source 

Researchers have made a groundbreaking discovery regarding the origins of non-meteoric water in natural spa waters located in central Japan. Based on numerical modeling, their results suggest that this water has been confined within the lithosphere for an extensive period of 1.5-5 million years. They identified three primary sources for this ancient water: the Philippine Sea Plate, the Pacific Plate, and ancient seafloor sediments, particularly in the Niigata and southwest Gunma regions.

Global study of extreme drought impacts on grasslands and shrublands      (via sciencedaily.com)     Original source 

A global study shows that the effects of extreme drought -- which is expected to increase in frequency with climate change -- has been greatly underestimated for grasslands and shrublands. The findings quantify the impact of extreme short-term drought on grassland and shrubland ecosystems across six continents with a level of detail that was not previously possible. It is the first time an experiment this extensive has been undertaken to generate a baseline understanding of the potential losses of plant productivity in these vital ecosystems.

Protecting coral 'nurseries' as important as safeguarding established coral reefs      (via sciencedaily.com)     Original source 

New research in the southwestern part of Hawai'i Island shows that identifying and protecting marine ecosystems both down-current and up-current of coral reefs, specifically areas where coral larvae are more likely to survive and thrive, is crucial to future coral conservation and restoration efforts -- especially as reefs face increasing pressure from the devastating effects of climate change.

Protected areas for elephants work best if they are connected      (via sciencedaily.com)     Original source 

The largest analysis yet of African savannah elephant populations shows that conservationists have successfully protected elephants in southern Africa for the last 25 years. However, the pattern varies regionally, with some elephant populations soaring and others still facing large declines. The key to long-term stability appears to be connecting large core areas with neighboring buffer zones, as opposed to well-protected but isolated protected areas known as 'fortress conservation.'

Conflict in full swing: Forest bats avoid large areas around fast-moving wind turbines      (via sciencedaily.com)     Original source 

Not only do many bats die at wind turbines, the turbines also displace some species from their habitats over large areas. When the turbines are in operation at relatively high wind speeds, the activity of bat species that hunt in structurally dense habitats such as forests drops by almost 80 per cent within a radius of 80 to 450 meters around the turbine.

The choreography connecting kelp forests to the beach      (via sciencedaily.com)     Original source 

A new study uncovers a symphony of synchrony between the kelp forest and beach, with broader implications for the beach food web as the climate changes.

Microbial awakening restructures high-latitude food webs as permafrost thaws      (via sciencedaily.com)     Original source 

Wildlife biologists used a novel technique to trace the movement of carbon through Arctic and boreal forest food webs and found that climate warming resulted in a shift from plant-based food webs to fungal-based food webs for several high-latitude species, with potential indirect effects on nutrient cycling and ecosystem function.

Evolution might stop humans from solving climate change      (via sciencedaily.com)     Original source 

Human culture has evolved to allow humans to extract resources and helped us expand to dominate the biosphere. But the same evolutionary processes may counteract efforts to solve new global environmental threats like climate change, according to a new study. Tackling the climate crisis will require worldwide regulatory, technical and economic systems supported by strong global cooperation. However, this new study concludes that the group-level processes characteristic of human cultural evolution, will cause environmental competition and conflict between sub-global groups, and work against global solutions. Adapting to climate change and other environmental problems will, therefore, require human evolution to change.

Understanding climate mobilities: New study examines perspectives from South Florida practitioners      (via sciencedaily.com)     Original source 

A recent study assessed the perspectives of 76 diverse South Florida climate adaptation professionals. A new study explores the expectations and concerns of practitioners from the private sector, community-based organizations, and government agencies about the region's ability to adapt in the face of increasing sea level rise and diverse consequences for where people live and move, also known as climate mobility.

From NYC to DC and beyond, cities on the East Coast are sinking      (via sciencedaily.com)     Original source 

Major cities on the U.S. Atlantic coast are sinking, in some cases as much as 5 millimeters per year -- a decline at the ocean's edge that well outpaces global sea level rise, confirms new research. Particularly hard hit population centers such as New York City and Long Island, Baltimore, and Virginia Beach and Norfolk are seeing areas of rapid 'subsidence,' or sinking land, alongside more slowly sinking or relatively stable ground, increasing the risk to roadways, runways, building foundations, rail lines, and pipelines, according to a new study.

How national policies affect forests in border regions      (via sciencedaily.com)     Original source 

How do national policies impact deforestation? Researchers have looked into this question at the global scale and have found that, contrary to common assumptions, national strategies have a significant -- and visible -- influence on efforts to protect forest heritage.

Millions of mysterious pits in the ocean decoded      (via sciencedaily.com)     Original source 

The world's ocean are a vast habitat for countless creatures that settle, spawn, dig or feed on the seafloor. They also influence the shape of the ocean floor. How exactly this takes place has been scarcely investigated so far. In an interdisciplinary study, geoscientists, biologists and oceanographers, have examined crater-like depressions on the seafloor of the North Sea. They were able to show that these directly relate to the habitats of porpoises and sand eels, and for the first time provide a conclusive explanation for the importance of vertebrates in shaping the seafloor.
