In Patagonia, more snow could prevent glaciers from melting, but only if greenhouse gas emissions are quickly curbed.
Glacier front in southern Patagonia. Credit: Henning Ã…kesson In an era of declining glaciers, southern Patagonia has managed to retain an astonishing amount of ice. But a new study published in Scientific Reports by INSTAAR postdoctoral researcher Matthias Troch suggests that this protective effect may soon reach its limit. Before making their predictions, Troch and his collaborators looked back. They…

Private jet carbon emissions jump 46%: study
Private jets, the preferred mode of transportation for the rich and famous, are the most energy-intensive form of flight, and the industry has long been a target of climate change protesters. Carbon emissions from private jet travel will increase by 46% between 2019 and 2023 and will continue to rise unless the ultra-luxury industry is regulated, according to new research…

Analysis shows no significant PFAS emissions under approved waste incineration conditions
Credit: Karlsruhe Institute of Technology Fluoropolymers have become an integral part of modern society, both in industrial and consumer applications. At the end of their useful life, these high-performance materials can become both industrial and domestic waste. Researchers at Karlsruhe Institute of Technology (KIT), in collaboration with international partners, analyzed the contribution of fluoropolymer waste incineration to the release of…

Study finds that calcium reduces COâ‚‚ emissions from Arctic soil through mineral formation
Written by Leibniz Zentrum Far Agralandschaftforschung (ZALF) eV Graphical summary. Credit: Environmental Science and Technology (2024). DOI: 10.1021/acs.est.4c07496 In a new study, researchers found that increasing calcium content in soil significantly reduces CO2 emissions. 50% in calcium-poor soils and 57% in calcium-rich soils. The reason is that calcium promotes the formation of the aragonite mineral, which binds CO2 and prevents…

China’s child policies will increase future carbon emissions, researchers say
Credit: Unsplash/CC0 Public Domain Relaxing restrictions on family size will make it harder for China to meet its goal of becoming carbon neutral by 2060, according to a new study by UCL researchers. The paper, published as a Policy Brief in the journal Nature Climate Change, is the first study to analyze the impact of national population policies on future…

Researchers say corals could survive climate change if carbon emissions are reduced
Hawaii’s coral reefs are teeming with life. Photo by Andre Seal In a study published in Proceedings of the Royal Society B, researchers from the Toonen Bowen (ToBo) lab at the University of Hawaii’s Hawaii Institute of Marine Biology (HIMB) identified scenarios in which eight of the most common coral species found in Hawaii could adapt and survive ocean warming…

Report: Reducing methane emissions key to fighting climate change and harmful ozone layer
Credit: Pixabay/CC0 Public Domain Many human activities release methane into the atmosphere. Agriculture, landfills, wastewater, and fossil fuel production and distribution are the largest sources of methane. These account for approximately 60% of global methane emissions, with the remaining 40% coming from natural sources. Like carbon dioxide (CO2), methane is a potent greenhouse gas and is estimated to be responsible…
