Scientists caution against a reliance on mechanical devices to clear water bodies of plastic      (via sciencedaily.com)     Original source 

An international group of scientists has called for the United Nations Treaty on Plastic Pollution to focus more on measures to reduce the production and consumption of plastics and the prevention of future plastic waste, rather than on the unselective removal of waste already in the water.

Plastics treaty must tackle problem at source      (via sciencedaily.com)     Original source 

The new Global Plastics Treaty must tackle the problem at source, researchers say. They say the treaty must prioritize 'upstream' issues: cutting total production and consumption of plastics, phasing out hazardous chemicals and tackling fossil fuel subsidies.

Exploring the origin of nucleosynthetic isotope variations in Ryugu samples      (via sciencedaily.com)     Original source 

The observed variations in chromium (Cr) isotope ratios in the Ryugu asteroid samples collected by Hayabusa2 likely resulted from elemental redistribution of slightly soluble Cr by water within the parent body, reveals a multinational study. The results provide useful insights for expanding our understanding of the origin and evolution of materials in our solar system.

Greenland's glacier retreat rate has doubled over past two decades      (via sciencedaily.com)     Original source 

A new study documents how Greenland's peripheral glaciers have changed from 1890 to 2022. Using satellite images and a unique archive of historical aerial photos, researchers documented changes in the lengths of more than 1,000 of the country's glaciers over the past 130 years. Although glaciers in Greenland have experienced retreat throughout the last century, the rate of their retreat has rapidly accelerated over the last two decades.

New findings support long-proposed process of planet formation      (via sciencedaily.com)     Original source 

Scientists just made a breakthrough discovery in revealing how planets are made. By observing water vapor in protoplanetary disks, they confirmed a physical process involving the drifting of ice-coated solids from the outer regions of the disk into the rocky-planet zone.

Maps reveal biochar's potential for mitigating climate change      (via sciencedaily.com)     Original source 

Twelve countries have the technical ability to sequester over 20% of their current total greenhouse gas emissions by converting crop residues to biochar. Bhutan leads the way with the potential to sequester 68% of its emissions in the form of biochar, followed by India, at 53%.

How to eat our way out of the climate crisis      (via sciencedaily.com)     Original source 

Researchers conducted a study to determine if replacing dietary fats from palm oil, soy and other agricultural crops with fats created synthetically in chemical or biological processes could help reduce climate change-causing greenhouse gases. The researchers' analysis finds a reduction in carbon emissions and other benefits, such the opening of agricultural lands to reforestation which benefits biodiversity and creates a carbon sink.

Keeping an eye on the regions when it comes to climate change      (via sciencedaily.com)     Original source 

Up to now, the results of climate simulations have sometimes contradicted the analysis of climate traces from the past. Physicists and climatologists have now brought together experts in climate models and climate tracks to clarify how the discrepancies come about. The surprising result has now been published: in a way, both sides are right. Climate models correctly simulate global temperature trends, but often underestimate the strength of regional climate fluctuations, especially over the course of decades to centuries.

Scientists map loss of groundwater storage around the world      (via sciencedaily.com)     Original source 

Global water resources are stretched by climate change and human population growth, and farms and cities are increasingly turning to groundwater to fill their needs. Unfortunately, the pumping of groundwater can cause the ground surface above to sink, as the aquifers below are drained and the architecture of the ground collapses. A new study maps this loss of groundwater storage capacity around the world.

Predicting saltwater intrusion into groundwater using Plymouth, Mass. as test case      (via sciencedaily.com)     Original source 

As the world warms and ice sheets melt, the ocean continually rises. The greater Boston area can expect to see between one and six feet of sea level rise by 2100, according to recent estimates. To find out what this rise might mean for freshwater supplies, a team of hydrogeologists developed an innovative new model that can not only predict saltwater intrusion over the next 75 years, but also pinpoint the main sources of salt contamination today -- road salt and human development.
