Researchers uncover growing dangers lurking beneath Greenland's ice: 'Damaging critical infrastructure'
The administration of United States President Donald Trump has not been coy about its interest in Greenland — not only for its strategic value, but for its plethora of oil and minerals. During the congressional hearing on the world's largest island, however, no one seemed concerned about the rapidly melting ice and whether it could prove to be a huge oversight. Greenland has been losing ice mass at an increasingly accelerated rate since 2002, according to NASA. Geoscientist Paul Bierman pointed out, in an article published by The Conversation, that the climate change-induced phenomenon has created landslide-prone terrain that would make any sort of extraction dangerous. Per the speed at which the Arctic climate is warming is four times faster than the rest of the world, which only exacerbates the degree of risk, both economic and personal, to pull resources. Bierman, who studies the environmental history of Greenland, emphasized how unpredictable the land is, often called the "land of extremes." The harsh climate and massive ice sheet create natural hazards that have grown exponentially worse as the planet continues to get warmer each year. Bierman wrote, "As the climate warms, permafrost — frozen rock and soil — which underlies the island, thaws. This destabilizes the landscape, weakening steep slopes and damaging critical infrastructure." Rockslides are capable of triggering catastrophic tsunamis, some of which have taken out nearby villages. With the constant threat of landslides, the conditions are uncertain at best, deadly at worst. Because of the land's instability, the infrastructure for what the United States has in mind simply doesn't exist. In fact, the article stated, "Greenland's government banned drilling for fossil fuels in 2021 out of concern for the environment." There are no routes connecting the coastal communities. Exporting minerals and oil would have to be done by sea, which would leave equipment and operations vulnerable to the elements, including icebergs, which are more prevalent with the warmer temperatures. The monumental risk and cost must be taken into consideration with the future in mind. What source of air pollution do you worry most about at home? Wildfires Gas stove Fireplace Something else Click your choice to see results and speak your mind. What's happening in Greenland isn't just devastating locally — it's bad news for all of us. When ice melts into the ocean, sea levels rise. This causes coastal erosion, threatens fresh water, and impacts ecosystems globally. If all of Greenland were to melt, it would raise the global sea level by around 23 feet, as the National Snow and Ice Data Center reported. Furthermore, the melting ice is being replaced by vegetation growth, creating a wetland of methane production. Methane has 80 times the warming power of carbon dioxide in its first 20 years in the atmosphere, per the Environmental Defense Fund. This is a direct cause of human-induced changes to the climate, which propel extreme weather events. Scientists and researchers are keeping a keen eye on Greenland, but to prevent a total meltdown, global temperatures need to go down, which will require a massive reduction of planet-warming pollution. That means less production and use of dirty energy and more focus on clean energy sources, like solar, wind, and hydro. Individually, it's important to educate yourself on critical climate issues. Being a part of the solution starts with understanding the problem. Use less plastic, walk when you can, use your car as efficiently as possible, and support circular brands to reduce your carbon impact.

Drink coffee daily? Health coach warns it may do more harm than you think: 'Setting the stage for losing your teeth'
Health and fitness coach Theo Bergmann advised against having coffee in a video he shared on Instagram on April 22. In his caption, he wrote, 'You have to understand this. Coffee is not the best option for your health!' In the accompanying video, Theo explained 'how dangerous coffee is'. Also read | Don't brush your teeth before sleeping? Doctor explains why skipping brushing may do more harm than just risk cavities He said, 'The biggest problem with coffee is that it is very acidic. Any kind of caffeine is very acidic. Your body has to buffer that acidity with calcium. Most people nowadays don't have enough calcium in their system anyway. They only have toxic calcium in their system from dairy. But if you have coffee every day, your body has to buffer that with lots of calcium for the acidity.' A post shared by Theo Bergmann | Certified Health Coach (@_theobergmann) Theo warned that excessive coffee consumption might lead to increased excretion of calcium, potentially contributing to osteoporosis (a condition characterised by weakened and brittle bones) over time, and added that coffee's acidity might contribute to tooth erosion. If good oral hygiene practices aren't followed, it could potentially lead to tooth loss, according to Theo. He said, 'What's happening is that if you don't have enough calcium in your bloodstream, your body is using the calcium from your bones and your teeth. Coffee is not only setting the stage for osteoporosis, but it is also setting the stage for losing your teeth – and on top of that, it is also dehydrating you so much, and it is ageing you faster.' A 2018 study published in examined the association between coffee intake and tooth loss. It found that daily coffee consumption is closely associated with tooth loss in Korean adults.

Tea-riffic choices: Oolong to chamomile, which tea is best for your health and mood?
Want to wind down before bed? A cup of chamomile tea proves to be calming and will help you sleep better. Shutterstock Ah, it's always tea time, as the Mad Hatter from Alice in Wonderland wisely said. There's always something deeply comforting about a hot brew, be it a morning pick-me-up or the evening wind-down. Avoiding the coffee debate, it's clear that tea offers just as many benefits—packed with antioxidants, calming properties, and even metabolism-boosting magic. From classic green tea to floral infusions, here are the different types of tea and why they deserve a spot in your daily routine, as explained by clinical dieticians. If teas had a 'most famous' category, green tea would win hands down. As Dubai-based Shama Chatterjee, a clinical dietician explains, It's filled with catechins, powerful antioxidants that help fight cell damage and support heart health. Notably, epigallocatechin gallate (EGCG), a prominent catechin in green tea, has been extensively studied for its positive effects on cardiovascular health. Moreover, according a recent Japanese study involving nearly 9,000 older adults found that those who consumed three or more cups of green tea daily had significantly fewer cerebral white matter lesions, which are indicators of cognitive decline. This aligns with previous research highlighting green tea's cognitive benefits. Best time to drink: Morning or early afternoon for a gentle energy boost without the jitters. Try it if: You want a clean, refreshing tea that supports weight management and overall wellness. Black tea: Bold and filled with energy For those who prefer a stronger, more robust flavour, black tea is the way to go. 'It's rich in theaflavins, which support heart health, reduce cholesterol, and improve gut health, and its caffeine content makes it a great coffee alternative,' adds Chatterjee. One 2016 study, published in Healthy Aging , found that regular consumption of black tea, along with oolong and green tea, was linked to a reduced risk of neurocognitive disorders like dementia, particularly among elderly women. If green tea isn't your cup of tea, black tea might be a great alternative for supporting metabolic health. A British Medical Journal review suggests it could help reduce the risk of type 2 diabetes. Black tea is also rich in flavonoids, plant-based compounds known for their potential health benefits. Research indicates that a flavonoid-rich diet may offer protective effects against cancer and heart disease. Best time to drink: Morning or midday for sustained energy and focus. Try it if: You enjoy a bold, slightly malty taste and need an extra kick to power through your day. Oolong tea: The metabolism boost Sitting between green and black tea in terms of oxidation, oolong tea combines the best of both worlds. Nidhi Sethi, a Dubai-based dietician explains, 'It's known for aiding digestion and boosting metabolism, making it a great choice if you're looking to support weight management. Plus, it's packed with polyphenols that support brain function and heart health.' If you're looking for a tea that might support your weight goals, oolong could be a great pick. Some research suggests that oolong tea extract may help reduce body fat and even play a role in preventing obesity. But before we call it a magic weight-loss brew, more studies are needed to confirm its effects. Beyond weight management, oolong tea is packed with potential health perks. A 2022 review highlighted its powerful antioxidative, anti-inflammatory, and even anticancer properties. Best time to drink: Midday, especially after meals, to aid digestion. Try it if: You love a tea with a rich, slightly floral, and complex flavour. The least processed of all teas, white tea is light, delicate, and brimming with antioxidants. It's often linked to skin health, as it helps combat premature aging and protects against UV damage. It's also known to support heart health and immune function, according to both Chatterjee and Sethi. Best time to drink: Any time of day—it's naturally low in caffeine, making it a great all-day option. Try it if: You want a mild, refreshing tea that benefits both your skin and overall wellness. Herbal teas: Medicine's nature cabinet From chamomile to peppermint, herbal teas offer natural remedies for everything from relaxation to digestion. Chamomile: Want to wind down before bed? A cup of chamomile tea proves to be calming and will help you sleep better. It could also give your immune system a little boost, One review found that it might help stimulate immune function, though the researchers pointed out that more clinical trials are needed to confirm this. A 2022 review, published on the National Library of Medicine, also uncovered that chamomile might have some impressive benefits, like anti-inflammatory, antioxidant, anticancer, and blood-pressure-lowering properties. Peppermint: Great for digestion, relieves headaches, and refreshes the senses. Peppermint is packed with menthol, a compound that helps relax the intestinal tract and can ease bloating, explains Chatterjee. Ginger: Tummy troubles? Ginger tea to the rescue. It is helpful for immunity, digestion, and inflammation, and can help with nausea too. Rooibos: Rich in antioxidants and good for heart health. Best time to drink: Evening or when you need a caffeine-free moment of relaxation. Try it if: You want a soothing, natural remedy for stress, digestion, or overall well-being. Matcha: The Zen superfood Matcha is essentially green tea, but tougher. Made from finely ground green tea leaves, it's loaded with L-theanine, which promotes relaxation without drowsiness. It's also an energy booster, metabolism revver, and antioxidant powerhouse. Best time to drink: Morning or before a workout for sustained energy. Try it if: You love a creamy, earthy tea that packs a nutritional punch. Sign up for the Daily Briefing Get the latest news and updates straight to your inbox
