Scientists have debated for decades whether economies can continue to grow without increasing greenhouse gas emissions. A new study by a Penn State researcher has found that this may be possible, but only under strict conditions and mostly for the world's wealthiest nations. The work includes the analysis of more...

New paired studies from the University of Minnesota Twin Cities show that machine learning can improve the prediction of floods. The studies, published in Water Resources Research and the Proceedings of the IEEE International Conference on Data Mining, demonstrate how "knowledge-guided" artificial intelligence can assist forecasters in saving lives and...

Energy-from-waste facilities are often positioned as a cleaner alternative to landfill, transforming rubbish into electricity and reducing the UK's waste burden. But new research suggests that there may be a hidden cost to this process: potentially hazardous chemical residues that remain largely out of public view. A study from the... Read more

Small changes to aircraft flight paths to avoid the atmospheric conditions that create condensation trails—known as contrails—could reduce aviation's global warming impact by nearly half, a new study suggests. The study, led by researchers at the University of Cambridge, suggests that changing cruising altitude by a few thousand feet, either... Read more

The legal rights designed to protect Afro-Colombian communities are not lifting them out of economic precarity—and are leaving them vulnerable to the illegal drug trade and illicit mining as a result—according to new research from The University of Manchester.... Read more

Diseases historically absent from the United States have been showing up in Florida, Texas, California and other U.S. states in recent years. To understand why, look to Peru. That's where researchers from Stanford and other institutions analyzed the connection between a cyclone and a massive outbreak of dengue fever, a... Read more

A new study reveals an unprecedented increase in wildfires in tropical peatlands during the 20th century. "Unprecedented burning in tropical peatlands during the 20th century compared to the previous two millennia" is published in Global Change Biology.... Read more

Navigating monolithic icebergs, massive ocean waves and sub-zero snowstorms, CSIRO research vessel (RV) Investigator is a workhorse for Antarctic science. In just over 11 years and spread across seven voyages, the vessel has now spent the equivalent of one full year, or more than 10% of its time, at sea... Read more

Reliable and scalable water level prediction is crucial in hydrology for effective water resources management, especially when considering challenges owing to climate change, urbanization, improper land use, and high-water demand. It directly impacts the availability and distribution of freshwater in rivers and reservoirs. Therefore, accurate forecasting via early warning systems... Read more

A new study published in The Lancet Global Health reveals a previously underappreciated tension at the heart of international climate negotiations: policies designed to protect developing countries from bearing an unfair share of the cost of cutting carbon emissions could inadvertently deprive those same countries of millions of life-saving air...

In the fight against the climate crisis, countries are pinning great hope in reforestation projects. In a new study, ETH Zurich researchers show that the location in which reforestation is taking place is usually more important than the number of trees planted. If forests are strategically positioned, the same cooling... Read more

New research reveals that changes following the recent and dramatic decline in Antarctic sea ice could help a low-nutritional species prosper, with major ramifications for food webs and biogeochemical cycles. The findings are published in the journal Marine Ecology Progress Series.... Read more

Biodegradable plastics could help alleviate the plastic waste crisis that is polluting the environment and harming our health. But how long plastics take to degrade and how environmental bacteria work together to break them down is still largely unknown.... Read more

A global analysis of more than 2,300 seawater samples from more than 20 field studies around the globe indicates that human-made chemicals make up a significant portion of organic matter in coastal oceans. The international study, led by biochemists Jarmo Kalinski and Daniel Petras at the University of California, Riverside,... Read more

When floods, coastal erosion or sea-level rise threaten settlements or infrastructure, European countries turn to managed retreat more often than previously assumed. Managed retreat refers to the planned, government-supported relocation of people, homes or infrastructure away from areas exposed to flooding and other climate-related hazards. A new German–Dutch study led... Read more
