I just returned from Antarctica: climate change isn’t some far-off problem – it’s here and hitting hard

Antarctica is often viewed as the last truly remote place on Earth – frozen, wild and untouched. But is it really as untouched as it seems?

This vast frozen continent is encircled by the Antarctic Circumpolar Current, the only current in the world that connects all the oceans, showing how closely linked our planet really is.

Earlier this year, I joined more than 100 scientists on a journey to Antarctica. What we encountered was extraordinary: towering icebergs, playful penguins, breaching whales and seals resting on the ice. Yet beneath this natural wonder lies a sobering reality – Antarctica is changing, and fast. The experience left me both inspired and deeply saddened.

This unique environment highlights the fragility of our planet. Its pristine landscapes and thriving wildlife represent what we stand to lose if we don’t take urgent action to reduce human impact.

Historically, Antarctica suffered from exploitation – hunters came for whales and seals, leaving scars on its ecosystems. While wildlife is slowly recovering, these species now face a new threat: climate change. Rising ocean temperatures are melting ice, reshaping habitats and disrupting the delicate balance of life.

The continent stands as a powerful symbol of our interconnected climate systems – a compelling case for conservation. During our visit, we toured research stations and Port Lockroy, where gentoo penguins raise their chicks. Here, human activity is carefully managed. Half the island is set aside for the penguins, while the other half welcomes around 18,000 tourists each year who come to learn about this remarkable place. It’s a model of coexistence – one that shows how we can live alongside nature when we choose to act responsibly.

Along our journey, we witnessed diverse wildlife in their natural habitats – from penguins and seals to whales and seabirds. Albatrosses and cape petrels followed our ship, gliding effortlessly over the waves – symbols of resilience, yet also vulnerability.

But reminders of past damage still linger. On Deception Island, rusted remains of the whaling industry serve as stark evidence of the harm unchecked exploitation can cause. They also underscore why continued protection of these fragile ecosystems is vital.

As an oceanographer, I study how the ocean shapes our world – and Antarctica is central to that story. The surrounding waters link the Pacific, Indian and Atlantic oceans through the Antarctic Circumpolar Current. This connectivity means that what happens in Antarctica affects us all. Pollution, warming seas and oil spills know no borders. These changes disrupt ocean currents, harm marine life and influence climate systems around the globe.

The implications are clear: addressing environmental challenges requires international cooperation and decisive action.skip past newsletter promotion

For Australia and other nations, the lesson is urgent. We must embrace sustainable practices, invest in renewable energy and support conservation efforts. By reducing carbon emissions and learning from the past, we can help protect Antarctica – and the planet – for future generations.

My journey wasn’t just about witnessing climate change – it was about understanding the deep interconnections that bind our world. And it’s not just about telling a story of adventure. It’s about sparking awareness of the power of science, leadership and collective action to drive meaningful change.

Antarctica, with all its beauty and vulnerability, reminds us what’s at stake – and why we must act now. The urgency is real. The responsibility is ours. Together, we can protect this extraordinary planet.

Non-contact exposure to dinotefuran disrupts honey bee homing by altering MagR and Cry2 gene expression

Non-contact exposure to dinotefuran disrupts honey bee homing by altering MagR and Cry2 gene expression Dinotefuran is known to negatively affect honeybee ( Apis mellifera ) behavior, but the underlying mechanism remains unclear. The magnetoreceptor ( MagR , which responds to magnetic fields) and cryptochrome ( Cry2 , which is sensitive to light) genes are considered to play important roles in honey bees’ homing and localization behaviors. Our study found that dinotefuran, even without direct contact, can act like a magnet, significantly altering MagR expression in honeybees. This non-contact exposure reduced the bees’ homing rate. In further experiments, we exposed foragers to light and magnetic fields, the MagR gene responded to magnetic fields only in the presence of light, with Cry 2 playing a key switching role in the magnetic field receptor mechanism ( MagR–Cry2 ). Yeast two-hybrid and BiFc assays confirmed an interactio...

“Global honey crisis”: Testing technology and local sourcing soars amid fraud and tampering concerns

“Global honey crisis”: Testing technology and local sourcing soars amid fraud and tampering concerns The World Beekeeping Awards will not grant a prize for honey next year due to the “inability” to thoroughly test honey for adulteration. The announcement comes amid the rise of honey fraud in the EU, where a 2023 investigation found that 46% of 147 honey samples tested were likely contaminated with low-cost plant syrups. Apimondia, the International Federation of Beekeepers’ Associations, organizes the event at its Congress, whose 49th edition will be held in Copenhagen, Denmark, in September 2025. The conference brings together beekeepers, scientists and other stakeholders. “We will celebrate honey in many ways at the Congress, but honey will no longer be a category, and thus, there will be no honey judging in the World Beekeeping Awards. The lessons learned from Canada 2019 and Chile 2023 were that adequate testing was impossible if we are to award winning honey at the Con...

New Report – Interlocked: Midwives and the Climate Crisis

New Report – Interlocked: Midwives and the Climate Crisis Earlier this year, midwives from 41 countries shared their experiences of working in communities affected by climate change through our survey, Midwives’ Experiences and Perspectives on Climate Change. Their voices shaped our new report, Interlocked: Midwives and the Climate Crisis , which highlights how midwives are already responding to the health impacts of climate disasters like floods, wildfires, and extreme heat—and why they must be included in climate action plans. What did we learn?Climate change is damaging community health: 75% of midwives reported that climate change is harming the communities they serve, with rising rates of preterm births, food insecurity, and restricted access to care during disasters like floods. Midwives are critical first responders: Midwives are often the first and only healthcare providers on the ground in crises, delivering care during wildfires, floods, and extreme heat. Midwives face signi...

Start the New Year Humming Like a Bee

Start the New Year Humming Like a Bee There are lots of opportunities to be as busy as a bee during these winter holidays. As we hustle toward the dawn of the New Year, it can be hard to notice that the natural world is actually suggesting something different for us right now. We’re past the solstice, but the winter still stretches ahead, the days are still short and the nights long. We’re being invited into a quieter, more inner-focused time. The ancient yogis were all about this inner focus. In India, for example, the Upanishads, the Sanskrit writings that accompanied the development of Hinduism — and alongside it, yoga — beginning around 800 B.C.E., went deeper than earlier texts had into philosophy and questions of being. With the goals of increased inner awareness and higher consciousness, yoga was at that time not yet as focused on the body or on asanas, as it now can tend to be. But the yogis did develop many practices to try to open the way to those goals. They discovered...

New data confirm catastrophic honey bee colony losses,underscoring urgent need for action

New data confirm catastrophic honey bee colony losses,underscoring urgent need for action Newly analyzed data confirm the staggering honey bee colony losses detailed last month of 1.6 million colonies lost with commercial beekeepers sustaining an average loss of 62% between June 2024 and March 2025. Additional survey responses and field analyses now paint an even darker picture, reinforcing concerns about the long-term viability of pollination services critical to U.S. agriculture. Experts warn that without immediate intervention, the ripple effects could drive up costs for farmers, disrupt food production and shutter many commercial beekeeping operations. “Beekeeping businesses are facing unprecedented challenges that threaten their survival from colony losses we haven’t seen in nearly 20 years. The swift response from stakeholders and the U.S. Department of Agriculture is critical in providing beekeepers with the data and information to make well informed decisions to sustain t...

The largest “killer hornets” in the world were exterminated in the US

The largest “killer hornets” in the world were exterminated in the US The US informed that it had exterminated the worldʼs largest hornets, nicknamed "killer hornets" — they are capable of occupying a hive of honey bees in just 90 minutes, decapitating all its inhabitants and feeding their offspring to their own. This was reported by the Department of Agriculture in Washington. The hornets, which can reach five centimeters in length, were previously called Asian giant hornets, but in 2019 they were also spotted in Washington state near the Canadian border. In China, these insects killed 42 people and seriously injured 1,675. A dead northern giant hornet (below) next to a native bald hornet. According to experts, the hornets could have entered North America in plant pots or shipping containers. The hornet can sting through most beekeeper suits because it produces nearly seven times more venom than a honeybee and stings multiple times. Thatʼs why the Washington Departme...

Climate Crisis Claims Glacier's Vital Climate Data Archive

Climate Crisis Claims Glacier's Vital Climate Data Archive A recent study published in Nature Geoscience reveals a distressing consequence of global warming: the irreversible loss of valuable climate data stored in alpine glaciers. The research, conducted by a team led by Margit Schwikowski from the Paul Scherrer Institute (PSI), underscores the alarming rate at which glaciers are melting and highlights the implications for climate research. The study focuses on the Corbassière glacier at Grand Combin in Switzerland, where ice cores drilled in 2018 and 2020 were intended to serve as vital climate archives. However, comparing the two sets of ice cores reveals a grim reality—global warming has rendered the glacier unsuitable as a reliable climate archive. Glaciers, renowned as climate archives, encapsulate valuable information about past climatic conditions and atmospheric compositions. The fluctuating concentrations of trace substances in ice layers provide insights into historica...
