New research sheds light on relationships between plants and insects in forest ecosystems      (via sciencedaily.com)     Original source 

Researchers have published new findings on how leaf-eating insects affect forest ecosystems worldwide. Researchers are aware of how large herbivores cycle nutrients in forests. They know much less, however, about how leaf-eating insects impact forest carbon and nutrient cycling.

Sea level changes shaped early life on Earth, fossil study reveals      (via sciencedaily.com)     Original source 

Shifts in the Earth's continental plates that drove long-term changes in sea level set the stage for the evolution of the earliest animals on Earth, a study suggests.

Scientists find a human 'fingerprint' in the upper troposphere's increasing ozone      (via sciencedaily.com)     Original source 

Scientists confirmed that much of ozone's increase in the upper troposphere is likely due to humans. A team detected a clear signal of human influence on upper tropospheric ozone trends in a 17-year satellite record starting in 2005.

Retreat of tropical glaciers foreshadows changing climate's effect on the global ice      (via sciencedaily.com)     Original source 

As they are in many places around the globe, glaciers perched high in the Andes Mountains are shrinking. Now, researchers have uncovered evidence that the high-altitude tropical ice fields are likely smaller than they've been at any time since the last ice age ended 11,700 years ago.

Half a billion-year-old spiny slug reveals the origins of mollusks      (via sciencedaily.com)     Original source 

Exceptional fossils with preserved soft parts reveal that the earliest mollusks were flat, armored slugs without shells. The new species, Shishania aculeata, was covered with hollow, organic, cone-shaped spines. The fossils preserve exceptionally rare detailed features which reveal that these spines were produced using a sophisticated secretion system that is shared with annelids (earthworms and relatives).

Tipping risks from overshooting 1.5 °C can be minimized if warming is swiftly reversed      (via sciencedaily.com)     Original source 

Current climate policies imply a high risk for tipping of critical Earth system elements, even if temperatures return to below 1.5 C of global warming after a period of overshoot. A new study indicates that this risk can be minimized if the warming is swiftly reversed. That is why reducing emissions in the current decade is crucial for the stability of the Earth systems functions, researchers write. They analyzed the tipping risks for four interconnected core climate tipping elements: the Greenland Ice Sheet, the West Antarctic Ice Sheet, the Atlantic Meridional Overturning Circulation (AMOC), and the Amazon Rainforest.

Downwind states face disproportionate burden of air pollution      (via sciencedaily.com)     Original source 

A recent U.S. Supreme Court decision to block a federal rule curbing interstate air pollution further complicates efforts to reduce emissions and adds to an already disproportionate burden on 'downwind' states, according to researchers.

Smell reports reveal the need to expand urban air quality monitoring, say researchers      (via sciencedaily.com)     Original source 

Researchers have uncovered surprising insights into the Vancouver region's 'smellscape' using data from the Smell Vancouver app. Analyzing 549 reports from one year of app data, they discovered that 'rotten' and 'chemical' odours dominated, making up about 65 per cent of submissions. These unpleasant smells were linked to self-reported health issues like headaches and anxiety, leading some residents to change their behaviours, like closing windows even in stifling-hot weather.

Recent volcanic 'fires' in Iceland triggered by storage and melting in crust      (via sciencedaily.com)     Original source 

Scientists have detected geochemical signatures of magma pooling and melting beneath the subsurface during the 'Fagradalsfjall Fires', that began on Iceland's Reykjanes peninsula in 2021. Samples show that the start of the eruption began with massive pooling of magma, contrasting initial hypothesis for magma ascent straight from the mantle.
