Carbon dioxide's heavy stamp on temperature: Doubling CO2 may mean 7 to 14 degree increase      (via sciencedaily.com)     Original source 

A doubling of the amount of CO2 in the atmosphere could cause an increase in the average temperature on earth from 7 to even a maximum of 14 degrees. That is shown in the analysis of sediments from the Pacific Ocean off the coast of California.

Up to 30 percent more time: Climate change makes it harder for women to collect water, study finds      (via sciencedaily.com)     Original source 

By 2050, climate change could increase the amount of time women in households without running water spend collecting water by up to 30 percent on global average, according to a new study. In regions of South America and Southeast Asia, the time spent collecting water could double due to higher temperatures. Scientists estimate the large welfare losses that could result from climate impacts and highlights how women are particularly vulnerable to changing future climate conditions.

Restoring the Great Salt Lake would have environmental justice as well as ecological benefits      (via sciencedaily.com)     Original source 

Inland seas around the world are drying up due to increasing human water use and accelerating climate change, and their desiccation is releasing harmful dust that pollutes the surrounding areas during acute dust storms. Using the Great Salt Lake in Utah as a case study, researchers show that dust exposure was highest among Pacific Islanders and Hispanic people and lower in white people compared to all other racial/ethnic groups, and higher for individuals without a high school diploma. Restoring the lake would benefit everyone in the vicinity by reducing dust exposure, and it would also decrease the disparities in exposure between different racial/ethnic and socioeconomic groups.

Much of the Nord Stream gas remained in the sea      (via sciencedaily.com)     Original source 

Much of the methane released into the southern Baltic Sea from the Nord Stream gas pipeline has remained in the water. This is shown by measurements taken by researchers from the University of Gothenburg.

When in drought: Researchers map which parts of the Amazon are most vulnerable to climate change      (via sciencedaily.com)     Original source 

Some areas of the Amazon rainforest are more resilient to drought than others, new research shows. But if not managed carefully, we could 'threaten the integrity of the whole system,' researchers say.

Advanced artificial intelligence: A revolution for sustainable agriculture      (via sciencedaily.com)     Original source 

The rise of advanced artificial intelligence (edge AI) could well mark the beginning of a new era for sustainable agriculture. A recent study proposes a roadmap for integrating this technology into farming practices. The aim? To improve the efficiency, quality and safety of agricultural production, while addressing a range of environmental, social and economic challenges.

Climate change: rising temperatures may impact groundwater quality      (via sciencedaily.com)     Original source 

As the world's largest unfrozen freshwater resource, groundwater is crucial for life on Earth. Researchers have investigated how global warming is affecting groundwater temperatures and what that means for humanity and the environment. Their study indicates that by 2100, more than 75 million people are likely to be living in regions where the groundwater temperature exceeds the highest threshold set for drinking water by any country.

An earthquake changed the course of the Ganges: Could it happen again?      (via sciencedaily.com)     Original source 

A major earthquake 2,500 years ago caused one of the largest rivers on Earth to abruptly change course, according to a new study. The previously undocumented quake rerouted the main channel of the Ganges River in what is now densely populated Bangladesh, which remains vulnerable to big quakes.

Wear it, then recycle: Designers make dissolvable textiles from gelatin      (via sciencedaily.com)     Original source 

Researchers hope their DIY machine will help designers around the world experiment with making their own, sustainable fashion and other textiles from a range of natural ingredients -- maybe even the chitin in crab shells or agar-agar from algae.

Ancient polar sea reptile fossil is oldest ever found in Southern Hemisphere      (via sciencedaily.com)     Original source 

An international team of scientists has identified the oldest fossil of a sea-going reptile from the Southern Hemisphere -- a nothosaur vertebra found on New Zealand's South Island. 246 million years ago, at the beginning of the Age of Dinosaurs, New Zealand was located on the southern polar coast of a vast super-ocean called Panthalassa. 'The nothosaur found in New Zealand is over 40 million years older than the previously oldest known sauropterygian fossils from the Southern Hemisphere.

Improving soil health yields unexpected benefits for farmers      (via sciencedaily.com)     Original source 

While farmer surveys suggest that carbon prices are still too low relative to the paperwork these programs demand, a new study finds that money alone does not explain either farmers' doubts about carbon markets or their interest in regenerative agriculture. Instead, many farmers view improving soil health as a way to improve their quality of life by reducing their dependence on agrochemical companies' products and advice.

The yuck factor counteracts sustainable laundry habits      (via sciencedaily.com)     Original source 

Most people today would lean towards environmentally friendly life choices, but not at the expense of being clean. When it comes to our washing habits, the fear of being perceived as dirty often wins out over the desire to act in an environmentally friendly way. And the more inclined we are to feel disgusted, the more we wash our clothes. This is shown by a unique study that examines the driving forces behind our laundering behaviours and provides new tools for how people's environmental impact can be reduced.

Scientists unravel drivers of the global zinc cycle in our oceans, with implications for a changing climate      (via sciencedaily.com)     Original source 

The understanding of the global zinc cycle in our oceans has important implications in the context of warming oceans. A warmer climate increases erosion, leading to more dust in the atmosphere and consequently more dust being deposited into the oceans. More dust means more scavenging of zinc particles, leading to less zinc being available to sustain phytoplankton and other marine life, thereby diminishing the oceans' ability to absorb carbon.

Ancient ocean slowdown warns of future climate chaos      (via sciencedaily.com)     Original source 

When it comes to the ocean's response to global warming, we're not in entirely uncharted waters. A new study shows that episodes of extreme heat in Earth's past caused the exchange of waters from the surface to the deep ocean to decline.

Dolphins with elevated mercury levels in Florida and Georgia      (via sciencedaily.com)     Original source 

Scientists found elevated mercury levels in dolphins in the U.S. Southeast. The highest levels were found in dolphins in Florida's St. Joseph and Choctawhatchee Bays. Researchers study dolphins because they are considered a sentinel species for oceans and human health. Like us, they are high up in the food chain, live long lives, and share certain physiological traits. Some of their diet is most vulnerable to mercury pollution and is also eaten by people.

Western agricultural communities need water conservation strategies to adapt to future shortages      (via sciencedaily.com)     Original source 

The Western U.S. is heavily reliant on mountain snowpacks and their gradual melt for water storage and supply, and climate change is expected to upend the reliability of this natural process. Many agricultural communities in this part of the country are examining ways to adapt to a future with less water, and new research shows that a focus on supplementing water supply by expanding reservoir capacity won't be enough to avert future water crises.
