Climate inaction undermines public support for lifestyle changes
New research into the public perception of climate change initiatives finds that whilst there is strong support for low-carbon lifestyles, inaction is limiting public beliefs that a low-carbon future is possible. The new study by the Centre for Climate Change and Social Transformations found that political and media debate that justifies inadequate mitigation efforts for climate change - termed 'discourses of delay' - is drastically impacting public perception in the UK.

New study confirms forever chemicals are absorbed through human skin
A study of 17 commonly used synthetic -forever chemicalshas shown that these toxic substances can readily be absorbed through human skin. New research, published in Environment International, proves for the first time that a wide range of PFAS (perfluoroalkyl substances) - chemicals which do not break down in nature - can permeate the skin barrier and reach the body's bloodstream.

The carbon stored globally by plants is shorter-lived and more vulnerable to climate change than previously thought, according to a new study. The findings have implications for our understanding of the role of nature in mitigating climate change, including the potential for nature-based carbon removal projects such as mass tree-planting.

’Forever chemicals’ found in English otters
New research by Cardiff University's Otter Project has found that PFAS, also known as 'forever chemicals', present in English otters, raising concerns about potential health impacts in the future. The Cardiff scientists tested otters from across the UK to monitor levels of PFAS in the environment, to gain an understanding of the concentration of these chemicals in the UK's freshwaters, their persistence in the environment and any ecological and health risks.

Video footage of Iceland's 2010 Eyjafjallajökull eruption is providing researchers from the University of Cambridge with rare, up-close observations of volcanic ash clouds - information that could help better forecast how far explosive eruptions disperse their hazardous ash particles. When Eyjafjallajökull erupted in 2010, it ejected roughly 250 million tonnes of volcanic ash into the atmosphere: much of which was blown over Europe and into flight paths.

A new study by the Milner Centre for Evolution suggests that mating systems of birds have a stronger effect on evolution rates than previously thought. New research led by the University of Bath's Milner Centre for Evolution shows that shorebird species where females breed with multiple males in each season evolve significantly faster than monogamous species.

EU climate policy: French manufacturers cut emissions by 43 million tonnes
The carbon emissions of French manufacturers fell by an estimated 15% during the first eight years of the EU Emissions Trading System policy. This is the key finding of a new study by experts at Imperial College Business School, in collaboration with the University of Virginia and University of Mannheim.

Textured tiles help endangered eels overcome human-made river obstacles
A new way of helping a critically endangered species of eel swim upstream during their migration has been tested by Cardiff researchers. The cheap and easy to retrofit method helps the fish overcome human-made obstacles such as culverts, weirs and flumes routinely used in UK waterways to enable river crossings via bridges and to regulate river flow.

PhD candidate Ben Williams (UCL Centre for Biodiversity and Environment Research and ZSL's Institute of Zoology) writes with a colleague about why they built SurfPerch, an AI led system to make it faster and easier for marine scientists to answer ecological questions. Coral reefs cover only 0.1% of the ocean's surface - yet they host 25% of all known marine species.

Researchers have developed a low-cost, energy-efficient method for making materials that can capture carbon dioxide directly from the air. The first and most urgent thing we've got to do is reduce carbon emissions worldwide, but greenhouse gas removal is also thought to be necessary to achieve net zero emissions and limit the worst effects of climate change.

Assumptions that tropical forest canopies protect from the effects of climate change are unfounded, say researchers. A severe risk is that species are no longer able to survive within tropical forests as climate change intensifies, further exacerbating the global extinction crisis and degrading rainforest carbon stocks.

Researchers have explored how the River Nile evolved over the past 11,500 years and how changes in its geography could have helped shape the fortunes of ancient Egyptian civilisation. Research published in Nature Geoscience reveals a major shift in the Nile around four thousand years ago, after which the floodplain in the Nile Valley around Luxor greatly expanded.

Focus on cities will boost benefits of air pollution action for most vulnerable
Meeting UK air pollution targets by focussing on urban areas will maximise health benefits for the most deprived communities. A study led by Imperial College London researchers shows that reducing typically urban sources of fine-particle air pollution like roads, wood burners, and machinery would also reduce inequalities in how different communities suffer the health impacts.

Two decades of cuckoo research have helped scientists to explain how battles between species can cause new species to arise This exciting new finding could potentially apply to any pairs of species that are in battle with each other..the coevolutionary arms race could cause new species to emerge - and increase biodiversity on our planet Rebecca Kilner The theory of coevolution says that when closely interacting species drive evolutionary changes in each other this can lead to speciation - the evolution of new species.

Study says 'biodegradable' teabags don't readily degrade in the environment and can harm earthworms Researchers say labelling should be improved to make clear teabags shouldn't be thrown away in domestic compost heaps. Some teabags manufactured using plastic alternatives do not degrade in soil and have the potential to harm terrestrial species, a new study has shown.

City officials were more likely to maintain climate action during the pandemic in places with more climate-related health issues affecting residents. Cities around the world were more likely to maintain climate action and enact 'green recovery' long-term plans after the pandemic if local decision-makers were more alert to the health risks of climate change, a new global study has shown.

Scientists have used volcanic ash and ocean models to track the journey of huge mats of seaweed floating across the Atlantic and causing chaos in the Caribbean. They found chemical traces of volcanic ash from the eruption of a volcano on St Vincent, in St Vincent and the Grenadines in the Caribbean, on sargassum seaweed that washed up four months later in Jamaica - 1,700 kilometres away.

A team of scientists from the USA and UK has used artificial intelligence (AI) to map the activities of seafloor invertebrate animals, such as worms, clams and shrimps, across all the oceans of the world. The research, led by Texas A&M University (USA) with investigators from the University of Southampton (UK) and Yale University (USA), combined large datasets, with machine learning techniques, to reveal the critical factors that support and maintain the health of marine ecosystems.

A new study in Australia has shown that shoppers making simple food and drink switches could reduce greenhouse gas emissions from groceries by 26%. Researchers from The George Institute for Global Health and Imperial College London's School of Public Health conducted the most detailed analysis ever on the environmental impacts of a country's food buying behaviour.

Ambitious targets are needed to end ocean plastic pollution by 2100
Research suggests that plastic pollution must be reduced by at least 5% every year to make progress towards UN targets by the end of the century. The study, a collaboration between researchers at Imperial College London and GNS Science, suggests that reducing plastic pollution by 5% per year would stabilize the level of microplastics - plastics less than 5 mm in length - in the surface oceans.
