Scientists uncover disturbing factor linked to increase in dead dolphins off UK coast — here's what you need to know
Scientists have found that rising ocean temperatures and industrial chemicals are causing the deaths of short-beaked common dolphins in the United Kingdom.
According to a report relayed by Phys.org, researchers from the Zoological Society of London discovered a link between warming temperatures and the spread of infectious disease in the dolphins. Results showed that these pressures have been building for decades, and it's finally catching up with the marine animals.
Waters near coasts with many industries have higher levels of toxic chemicals, including polychlorinated biphenyls. These chemicals build up in the fatty tissues of dolphins and impair their immune systems and reproduction. While PCBs have been banned in Europe for around 40 years, the leftover chemicals continue to spill into marine environments from runoff and other sources.
Higher sea surface temperatures have disrupted biodiversity and changed species distributions, altering how infectious microorganisms move through the environment. Warmer waters have been linked with higher disease rates in several marine species.
Rising ocean temperatures have also led to changes in habitat use and prey availability for the short-beaked dolphins.
Short-beaked dolphins are crucial for healthy marine ecosystems, as they maintain the balance of marine food webs and form "super pods" with other dolphins that can influence prey availability and distribution. Deaths among these gentle creatures are concerning, as they may upset the balance of ecosystems and marine habitats.
Dolphins have been known to help people in numerous ways, including rescuing people from sharks, guiding boats, and helping with fishing. It's important that we protect them both for their survival and human benefits.
Global heating isn't only impacting dolphins — it's harming other animals across the world, including lambs in Spain, monkeys in Mexico, and elephants in Africa.
Scientists said they will continue to monitor marine environments for industrial pollutants. However, they noted that without taking steps to reduce environmental contaminants and reduce warming, risks to dolphins will likely increase in the future. The authors noted there's an urgent need to deploy conservation efforts that mitigate warming ocean temperatures and industrial chemicals in waterways.
On a positive note, endangered Irrawaddy dolphins, which are native to Southeast Asia, are seeing a population boost thanks to conservation efforts. If we make similar strides with the short-beaked dolphins, it will ensure their population remains stable.
By getting involved in your local community with wildlife groups, you can make a positive impact that can last for generations. Also, if you see anyone dumping chemicals into waterways, notify the proper authorities — this will keep dolphins and humans safe.

Revolutionary farming technique may have solved one of agriculture's toughest challenges: 'A historic step towards the future'
A pioneering farming experiment in drought-stricken Chile may have just cracked one of agriculture's biggest challenges: growing rice with less water. In a first-of-its-kind trial, researchers at Chile's Austral University and local farmers have successfully cultivated rice using a technique called "Jaspe" straining, without flooding the fields. The Jaspe strain consists of "spacing the seedlings further apart in enriched soil, and watering only sporadically to build a more resilient root system," according to an article by Typically, rice requires an enormous amount of water to grow, which becomes a major problem in places like Chile, where a megadrought has persisted for over a decade. By shifting away from traditional methods of growth, which require an enormous amount of water, the Jaspe strain could offer a lifeline to farmers in regions where every drop counts. "Irrigating rather than flooding rice fields is a historic step towards the future," said Javier Munoz, an early user of the Jaspe strain. The results were a surprisingly healthy crop, produced with a fraction of the usual water. "Using Jaspe in combination with a growing method that requires only intermittent watering cut the Munoz family's water consumption in half in a country that has for generations cultivated rice in flooded fields, or paddies," according to the article. "Rice cultivation in flooded paddies crawling with microorganisms is responsible for about 10% of human-caused methane emissions," according to the United Nations Food and Agriculture Organization. For everyday people, this type of innovation could mean more stable food prices, better access to nutritious staples like rice, and cleaner air and water, especially in communities hit hardest by pollution and climate stress. Do you take steps to conserve water at home? All the time Usually Sometimes Never Click your choice to see results and speak your mind. Reducing methane and water waste in farming helps lower the environmental impact of our food, creating ripple effects that benefit everyone. It's a step toward cleaning up the agriculture industry. In a world where climate pressures are mounting and freshwater is running low, Jaspe offers something we can all root for: a more sustainable future, one resilient rice plant at a time.

Researchers sound alarm as concerning phenomenon threatens water supply for more than 90 million people: 'The situation is serious'
The glaciers of the Andes Mountains are melting at alarming rates, which could lead to permanent water loss, threatening the water supply of over 90 million people, Cosmos magazine reported. Scientists at the University of Sheffield, England, who have been studying the reduction of Andes glaciers, found that the glaciers have been receding at a rate of 0.7 meters (about 2.3 feet) per year, as relayed by That is 35% quicker than the global average. Burning dirty energy sources releases harmful heat-trapping gases, such as carbon and methane, that contribute to rising global temperatures and melting glaciers. Warmer temperatures also mean that during the region's wet season (typically around December to April), the precipitation that falls is rain and less snowfall, resulting in less snowpack on the glaciers. The Andes mountain communities depend on snowmelt runoff during the dry season (around May to October) for freshwater supply, which is threatened by rising global temperatures and the subsequent lack of snow. This loss is compounded by the shrinking glaciers, which lead to permanent water losses in the region. While the immediate, short-term effect of melting glaciers is an increase in water flow from the mountains to the rivers, that water supply runs off freely to the lower areas of the mountains. Unusually fast-melting snow could become dangerous for nearby mountain communities, which may experience destructive flooding downstream, per the National Snow and Ice Data Center. Without water catchment systems to catch and store the melting snow runoff, mountain communities may see their fresh water supply decrease and permanently disappear from the region. Communities with fewer resources to build these water catchment systems have no agency in securing their water supply. As the glaciers melt, too, the darker rock face on the mountains becomes exposed, absorbing more of the sun's heat, which becomes a hopeless cycle for rapid glacier melting. Scientists have also studied the harmful effects of glacier melting on the environment. For example, melting glaciers release the ancient methane gas trapped in underground reservoirs in the Arctic, which were capped by permafrost glaciers. As the glaciers melt, the trapped gas gets released back into the atmosphere, acting as a bubble, trapping heat on the planet. How often do you worry about the quality of your drinking water? Never Sometimes Often Always Click your choice to see results and speak your mind. Morocco recently celebrated a remarkable recovery from significant water supply loss in the nation. Taking advantage of the increased rainfall in the region, Morocco built 130 dams to increase the nation's water storage capacity — which has since increased by 700%. Communities living by the ocean may soon be able to take advantage of the water supply near them. Researchers at the University of Illinois Urbana-Champaign developed a new electrode for battery-based water desalination, which may make water desalination more efficient and viable for coastal communities. "The situation is serious, and it will take global cooperation to tackle climate change and make a meaningful difference for the communities around the world most vulnerable from the effects of climate change," said Dr. Jeremy Ely, senior lecturer at the University of Sheffield's School of Geography and Planning, per Cosmos magazine.
