Spanish and Peruvian researchers analyzed the soil four years after a major wildfire in Arequipa, finding severe organic carbon loss, soil compaction, and erosion. These changes threaten water retention and increase risks for nearby endangered ecosystems, such as Polylepis forests.
Extreme weather events are becoming more frequent as a result of climate change. River floods such as those along the Ahr and Meuse valleys in 2021, the Central European floods of last September and the recent floods in Valencia, Spain, are caused by so-called cut-off lows. The Wegener Center at the University of Graz has now for the first time investigated how these storms could change with climate change. "We expect that persistent cut-off lows north of 40 degrees latitude and in East Asia will occur earlier in the year. Canada, northern Europe, Siberia and China in particular will have to prepare for more heavy and prolonged heavy rainfall in spring," says project leader Douglas Maraun. The results of the study have just been published in the scientific journal Communications Earth & Environment.
Reintroducing wolves to the Scottish Highlands could lead to an expansion of native woodland which could take in and store one million tonnes of CO2 annually, according to a new study led by researchers at the University of Leeds.
The cool conditions which have allowed ice caps to form on Earth are rare events in the planet’s history and require many complex processes working at once, according to new research.
Companies around the world are underestimating their total greenhouse gas footprints because of inconsistent accounting standards for methane emissions, finds a new study by researchers from UCL and Imperial College London.
This Valentine’s Day, millions of pounds worth of chocolate will be exchanged as gifts, but climate change and biodiversity loss imperil future global supplies of this treat. A new research study led by the University of Oxford and published today (14 February) demonstrates that sustainable agricultural practices that both protect pollinator populations and mitigate climate risks could help secure- and even improve - global cocoa yields.
In a paper published in National Science Review, an international team of scientists discovered a universal N2O emission baseline that could guide the sustainable management of riverine N2O. The discovery of EF-lines emphasized the importance of targeting hotspots and managing baseline emissions sustainably to balance social and environmental benefits. The priority control of organic and NH4+ pollution could rapidly eliminate global riverine N2O hotspots and reduce emissions by half. However, the further restoration of baseline emissions on nitrate removal is a long-term challenge.
Porous organic crystals with superior properties as CO2 adsorbents were created by researchers at Institute of Science Tokyo. Owing to the novel 2.5-dimensional skeleton, the materials feature ultrahigh-density amines. The covalently-bonded microporous skeleton and high crystallinity realize fast CO2 adsorption and high thermal stability. Their low adsorption heat, only one-fourth of the current amine scrubbing method, and their light-elemental nature can reduce the cost for CO2 separation from flue gases.
