Children born in 2020 will face 'unprecedented lifetime exposure' to climate extremes, and other nature and climate news

1. Over 50% of children born in 2020 will face 'unprecedented lifetime exposure' to climate extremes

Heatwaves, droughts and wildfires.

More than half of the children born in 2020 and beyond will face 'unprecedented lifetime exposure' to these climate extremes.

That's according to a study published in Nature, which says this will be the case even if warming is limited to 1.5C above pre-industrial temperatures, as the Paris Agreement outlines.

The authors explain 'unprecedented lifetime exposure' as exposure so high that it has only a one-in-10,000 chance of happening in a pre-industrial climate.

The research used a case study focused on Brussels to show that people born in 2020 will experience 11 heatwaves in their lifetime, even if the world does manage to meet the 1.5C warming target.

To illustrate the impact of human-induced climate change, the authors state that a person living in Brussels in a pre-industrial climate would experience three heatwaves in their lifetime.

The chance of facing unprecedented lifetime exposure to heatwaves is substantially larger among population groups characterized by high socioeconomic vulnerabilities, the study found.

2. Hawaii set to raise tourist taxes to fund climate relief

A first-of-its-kind legislation is one signature away from coming into law in Hawaii.

The island state has passed a 'green fee' bill, which will increase the state's lodging tax to provide additional funds for environmental protection and defence against natural disasters and climate extremes, The Guardian reports.

This bill adds a 0.75% tax to the state's existing tax on accommodations, such as hotel rooms, timeshares and vacation rentals.

A larger 11% tax will be applied to cruise ship bills, which are prorated depending on the number of days the vessels linger in Hawaii ports.

3. News in brief: Other top nature and climate stories this week

The European Union's planned changes to sustainability reporting rules could 'expose European companies to more climate change-related lawsuits', legal scholars have stated in a letter published online, Reuters reports.

Dying satellites could negatively impact ozone recovery and release pollution into Earth's atmosphere, a study published in the Journal of Geophysical Research Atmospheres has found. Most old satellites are disposed of by reducing their altitude and letting them burn up as they fall, releasing pollution.

The four-day storm that caused flooding across the central Mississippi Valley in April was made about 9% more intense and 40% more likely as a result of human-induced climate change, a study from the World Weather Attribution has found.

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...
