Impact of climate change on marine life much bigger than previously known      (via sciencedaily.com)     Original source 

Fish and invertebrate animals are far more affected by warmer and more acidic seawater than was previously known. The big gain of the new method is that more details become known about effects of climate change on species.

Subterranean storage of hydrogen      (via sciencedaily.com)     Original source 

Scientists are using computer simulations and laboratory experiments to see if depleted oil and natural gas reservoirs can be used for storing carbon-free hydrogen fuel. Hydrogen is an important clean fuel: It can be made by splitting water using solar or wind power, it can be used to generate electricity and power heavy industry, and it could be used to power fuel-cell-based vehicles. Additionally, hydrogen could be stored for months and used when energy needs outpace the supply delivered by renewable energy sources.

Humans converted at least 250,000 acres of estuaries to cities, farms in last 35 years      (via sciencedaily.com)     Original source 

Worldwide over the past 35 years, dams and land reclamation activities converted 250,000 acres of estuary -- an area roughly 17 times the size of Manhattan -- to urban land or agricultural fields, with most land conversion and estuary loss in rapidly developing countries, a new study finds. The findings could help developing countries avoid problems faced by countries that have already lost or degraded their estuaries.

A smarter city skyline for flood safety      (via sciencedaily.com)     Original source 

With climate change and rising urbanization, the likelihood and severity of urban flooding are increasing. But not all city blocks are created equal. Researchers investigated how urban layout and building structures contribute to pedestrian safety during flooding. Based on their simulated results, the team recommends modifying building corners and protective block layouts to reduce pedestrian risk.

A natural touch for coastal defense      (via sciencedaily.com)     Original source 

Common 'hard' coastal defenses, like concrete sea walls, might struggle to keep up with increasing climate risks. A new study shows that combining them with nature-based solutions could, in some contexts, create defenses which are better able to adapt.

How climate change will impact food production and financial institutions      (via sciencedaily.com)     Original source 

Researchers have developed a new method to predict the financial impacts climate change will have on agriculture, which can help support food security and financial stability for countries increasingly prone to climate catastrophes.

Deep parts of Great Barrier Reef 'insulated' from global warming -- for now      (via sciencedaily.com)     Original source 

Some deeper areas of the Great Barrier Reef are insulated from harmful heatwaves -- but that protection will be lost if global warming continues, according to new research.

Boreal forest and tundra regions worst hit over next 500 years of climate change, study shows      (via sciencedaily.com)     Original source 

Modelling climate change over a 500 year period shows that much of the boreal forest, the Earth's northernmost forests and most significant provider of carbon storage and clean water, could be seriously impacted, along with tundra regions, treeless shrublands north of the boreal forest that play a significant role in regulating the Earth's climate.

PFAS 'forever chemicals' above drinking water guidelines in global source water      (via sciencedaily.com)     Original source 

PFAS (aka 'forever chemicals') are notoriously difficult to destroy. They've been linked to environmental and health issues, including some cancers, but a lot remains unknown about the true scale and potential impacts of the problem -- including how much is in our water supply. A new study assessed the levels of PFAS contamination in surface and ground water around the globe -- and found that much of our global source water exceeds PFAS safe drinking limits.

Dinosaur study challenges Bergmann's rule      (via sciencedaily.com)     Original source 

A new study calls into question Bergmann's rule, an 1800s-era scientific principle stating that animals in high-latitude, cooler climates tend to be larger than close relatives living in warmer climates.

Common loons threatened by declining water clarity      (via sciencedaily.com)     Original source 

The Common Loon, an icon of the northern wilderness, is under threat from climate change due to reduced water clarity, according to a new study. The study followed up an earlier paper that showed substantial reproductive decline in the author's study area in northern Wisconsin.

eDNA methods give a real-time look at coral reef health      (via sciencedaily.com)     Original source 

The study underscores the crucial role of microbes in maintaining coral reef health, akin to the human gut microbiome. Hurricanes and disease outbreaks affect coral reef water microbial communities, leading to changes that may support further reef decline. Microbial analysis enables prompt assessment of disturbances' impacts on coral reefs, facilitating timely interventions to support reef ecosystems. Environmental DNA (eDNA) analysis offers a noninvasive approach to study coral microbial communities and diagnose reef health.

Heat stress from ocean warming harms octopus vision      (via sciencedaily.com)     Original source 

While climate change has led to an increase in the abundance of octopuses, heat stress from projected ocean warming could impair their vision and impact the survivability of the species.

What four decades of canned salmon reveal about marine food webs      (via sciencedaily.com)     Original source 

Researchers have shown that levels of anisakid worms -- a common marine parasite -- rose in two salmon species in the Gulf of Alaska and Bristol Bay over a 42-year period. The team discovered this by studying salmon caught, killed and canned from 1979 to 2021. Since anisakid worms have a complex life cycle involving multiple types of hosts, the researchers interpret their rising numbers as a potential sign of ecosystem recovery, possibly driven by rising numbers of marine mammals thanks to the 1972 Marine Mammal Protection Act.

Researchers envision sci-fi worlds involving changes to atmospheric water cycle      (via sciencedaily.com)     Original source 

Human activity is changing the way water flows between the Earth and atmosphere in complex ways and with likely long-lasting consequences that are hard to picture. Researchers enlisted water scientists from around the globe to write story-based scenarios about the possible futures humanity is facing but perhaps can't quite comprehend yet. The results are part of a creative pathway to understand atmospheric water research with an eye towards the potential economic and policy issues that may be just beyond the horizon.
