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.

AI-driven plant root analysis      (via sciencedaily.com)     Original source 

As part of an investigation to boost agricultural yields and develop crops that are resilient to climate change, Berkeley Lab scientists have introduced RhizoNet, a computational tool that harnesses the power of AI to transform how we study plant roots and root behavior under various environmental conditions. A paper describing their innovative deep-learning approach, combined with a unique hydroponic device that facilitates in-situ plant imaging, was published June 5 in Scientific Reports.

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.

Climate models underestimate carbon cycling through plants      (via sciencedaily.com)     Original source 

The carbon stored globally by plants is shorter-lived and more vulnerable to climate change than previously thought, according to a new study.

Non-native plants and animals expanding ranges 100 times faster than native species      (via sciencedaily.com)     Original source 

An international team of scientists has recently found that non-native species are expanding their ranges many orders of magnitude faster than native ones, in large part due to inadvertent human help. Even seemingly sedentary non-native plants are moving at three times the speed of their native counterparts in a race where, because of the rapid pace of climate change and its effect on habitat, speed matters. To survive, plants and animals need to be shifting their ranges by 3.25 kilometers per year just to keep up with the increasing temperatures and associated climactic shifts -- a speed that native species cannot manage without human help.

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.

Natural hazards threaten over three thousand species      (via sciencedaily.com)     Original source 

Natural hazards can speed up the extinction process of land animals that have limited distribution and/or small populations. But there is hope to turn the negative development around, says researchers behind new study.

Restored rat-free islands could support hundreds of thousands more breeding seabirds      (via sciencedaily.com)     Original source 

Archipelago case-study shows that removing invasive rats and restoring native vegetation could help bring back hundreds of thousands of breeding pairs of seabirds lost to tropical islands. Calculating that there are enough fish to sustain restored seabird populations should be an important consideration for restoration projects, scientists say. Restored seabird populations also provide huge boost to the health of surrounding coral reef ecosystems through restored nutrient cycles.

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.

Understanding the Green Sahara's collapse      (via sciencedaily.com)     Original source 

Abrupt shifts within complex systems such as the Earth's climate system are extremely hard to predict. Researchers have now succeeded in developing a new method to anticipate such tipping points in advance. They successfully tested the reliability of their method using one of the most severe abrupt climate changes of the past: the shift of the once-green Sahara into a desert.

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.

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.

A conservation market could incentivize global ocean protection      (via sciencedaily.com)     Original source 

Thirty-by-thirty: protect 30% of the planet by 2030. While conservation is popular in principle, the costs of actually enacting it often stall even the most earnest efforts. Researchers have now proposed a market-based approach to achieving the 30x30 targets in the ocean.
