Aircraft Turbulence is Worsening with Climate Change. Studying Birds Could Help

As climate change intensifies, the skies are becoming increasingly turbulent, posing risks to aircraft and passengers. Severe turbulence, once a rare occurrence, is now more frequent due to the warming planet. This phenomenon, known as clear-air turbulence, happens without visible clouds, making it particularly dangerous as it cannot be detected by traditional radar systems.

The Impact of Climate Change

Climate change is causing greater temperature differences between warm and cold air masses. This destabilization of the jet stream leads to more frequent and severe clear-air turbulence. A recent incident involving a Singapore Airlines flight highlighted the dangers of this invisible turbulence, resulting in injuries and a fatality.

Learning from Birds

Researchers are turning to the animal kingdom for solutions. Birds, which often encounter turbulent air, have adapted various strategies to navigate these challenging conditions. By studying birds like frigate birds and homing pigeons, scientists hope to gain insights that can improve turbulence prediction and aircraft design.

Frigate birds, for instance, rely on strong updrafts in turbulent cloud systems to reach high altitudes. Homing pigeons, which have been observed flying through strong turbulence, can cope with conditions that even challenge ultralight aircraft.

Innovative Research Methods

Emily Shepard and her team at Swansea University are leading the way in this research. They have conducted studies flying alongside pigeons, using GPS and other sensors to measure turbulence levels. These bird-borne sensors offer a unique way to collect continuous data on air conditions, potentially providing more accurate predictions of turbulence.

Practical Applications

The insights gained from studying birds could revolutionize how we predict and manage turbulence. Improved models could lead to better flight planning and safer air travel. Additionally, understanding how birds navigate urban turbulence could inform the design and operation of unmanned aerial vehicles (UAVs) in cities.

Conclusion

As climate change continues to affect our atmosphere, finding innovative ways to cope with increased turbulence is crucial. By learning from birds, we can develop better methods to predict turbulence and design aircraft that can handle these challenging conditions more effectively. This research not only has the potential to make air travel safer but also offers a fascinating glimpse into the natural world's solutions to complex problems.

Climate change is increasing the frequency and severity of turbulence experienced by aircraft. Severe turbulence, which can cause injuries and structural damage, is becoming more common due to warming temperatures. Researchers suggest that studying birds, which navigate turbulent air efficiently, could provide insights into better predicting and managing turbulence. Birds like frigate birds and homing pigeons have adapted to deal with extreme turbulence and could inform new models for predicting turbulence and even improve aircraft design.

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...

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...

The Growing Dilemma of Pet Burials in South Korea: Environmental and Legal Hurdles

The Growing Dilemma of Pet Burials in South Korea: Environmental and Legal Hurdles As the number of pets in South Korea steadily increases, pet owners face a growing dilemma due to the limited number of pet cemeteries across the country. Under the current legal framework, pet remains are classified as household waste, requiring specific disposal methods that are neither convenient nor easily accessible for all citizens. The imbalance between the rising pet population—over 5.52 million households with pets by the end of 2022—and the mere 70 registered pet cemeteries has led to significant challenges. This shortage is particularly evident in regions like Jeju Island, where pet owners must undergo arduous journeys to the mainland to ensure their pets receive proper burials. The root cause of this shortage lies in the strict regulations governing the establishment of pet cemeteries. These facilities, which must include crematoriums, face numerous restrictions, such as proximity to resident...

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...

German election: Climate and environment take a back seat

German election: Climate and environment take a back seat When the coalition government comprising the center-left Social Democratic Party (SPD) , Greens and neoliberal Free Democratic Party (FDP) emerged after the last German federal election in the fall of 2021, then-incoming Chancellor Olaf Scholz (SPD) did not object to being called the "climate chancellor." That was no surprise: the climate crisis had been a top issue during the election campaign. The new government made the fight against climate change a task for the Economy Ministry and appointed Vice Chancellor Robert Habeck from the Greens as its head. Three and a half years later, campaign speeches barely mention climate protection. The dominant issues are how to curb irregular immigration and how to boost Germany's sluggish economy. Skeptical view of renewable energy The head of the center-right Christian Democratic Union (CDU) , Friedrich Merz ...
