Greenland fossil discovery reveals increased risk of sea-level catastrophe      (via sciencedaily.com)     Original source 

Seeds, twigs, and insect parts found under two miles of ice confirm Greenland's ice sheet melted in the recent past, the first direct evidence that the center -- not just the edges -- of the two-mile-deep ice melted away in the recent geological past. The new research indicates that the giant ice sheet is more fragile than scientists had realized until the last few years -- and reveals increased risk of sea-level catastrophe in a warmer future.

Forecasting climate's impact on a debilitating disease      (via sciencedaily.com)     Original source 

In Brazil, climate and other human-made environmental changes threaten decades-long efforts to fight schistosomiasis, a widespread and debilitating parasitic disease. Now, researchers have developed models that can predict how the disease risk will shift in response to environmental changes.

Ultrafine particles linked to over 1,000 deaths per year in Canada's two largest cities      (via sciencedaily.com)     Original source 

A new study conducted in Canada's two largest cities has linked about 1,100 premature deaths per year to an unregulated air pollutant. Ultrafine particles (UFPs) primarily come from vehicle emissions and industrial activities. Canada's federal and provincial governments have not set concentration limits for UFPs, as they have for larger fine particles known as PM2.5.

Link between global warming and rising sea levels      (via sciencedaily.com)     Original source 

A new study suggests that Earth's natural forces could substantially reduce Antarctica's impact on rising sea levels, but only if carbon emissions are swiftly reduced in the coming decades. By the same token, if emissions continue on the current trajectory, Antarctic ice loss could lead to more future sea level rise than previously thought.

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.

Combined effects of plastic pollution and seawater flooding amplify threats to coastal plant species      (via sciencedaily.com)     Original source 

A new study highlights how a combination of environmental stressors -- namely plastic pollution and seawater flooding -- can increase the threats faced by plants in some of the planet's critical ecosystems. It showed that both stressors had some effects on the species tested, but being exposed to both microplastics and flooding together -- a threat likely to increase as a result of climate change and plastic use -- had a more pronounced impact on their resource allocation.

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.

Genetic signatures of domestication identified in pigs, chickens      (via sciencedaily.com)     Original source 

Wild boars and red junglefowl gave rise to common pigs and chickens. These animals' genes evolved to express themselves differently, leading to signatures of domestication -- such as weaker bones and better viral resistance -- in pigs and chickens, according to a research team.

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.

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.
