Beware the Derogators: The Geneva Conventions Turn 75

On August 12, 1949, the four Geneva Conventions were adopted, laying the basis of a normative standard in international humanitarian law.  As Balthasar Staehelin, personal envoy of the International Committee of the Red Cross (ICRC) president to China, stated at an anniversary event at the Swiss Embassy in Beijing, “In the past 75 years, the four Geneva Conventions have been fundamental in protecting persons affected by armed conflict, and international humanitarian law remains as relevant today for contemporary armed conflicts, as it was 75 years ago.”

The very first Geneva Convention, inspired by the activism of Swiss businessman Henry Dunant and the International Committee for the Relief of Wounded Combatants, was adopted as far back as 1864.  The instrument was intended to protect the vulnerable and wounded members of armed forces, and those responsible for their care.  Three revisions and expansive updates followed: 19061929 and 1949.

The Fourth Convention saw a legal revolution, crucial for offering protection for civilians, described by international jurist Hersch Lauterpacht as covering “entirely new ground not touched by the Hague Conventions”.  It was also inspired in its novelty by recognising “certain minimum obligations of humane treatment even in armed conflicts which are not of an international character and even if the parties to the conflict, which may not be states, are not parties to the Convention”.

Of significance is Article 4, which defines the reach of such protection as covering persons “who, at any given moment and in any manner whatsoever, find themselves, in case of a conflict or occupation, in the hands of a Party to the conflict or Occupying Power of which they are not nationals.”

In humanitarian law, the gulf between observance and violation can be vast.  In 2023, the United Nations recorded the deaths of 33,443 civilians in armed conflict.  This constituted a 72% increase on those from 2022.  Joyce Msuya, Assistant Secretary-General for Humanitarian Affairs and Deputy Emergency Relief Coordinator, cited conflicts in Gaza, Sudan, the Democratic Republic of the Congo, Myanmar, Nigeria, the Sahel, Somalia, Syria and Ukraine.

In her May address to the UN Security Council, Msuya noted more than 2,300 instances of violence and other forms of interference against those working in the medical field, along with patients, associated facilities, equipment and transport.  By mid-year, a staggering 110 million individuals had been displaced due to the prevalence of conflicts, instances of persecution, violence and human rights breaches.  These are the numbers of the invisible in speedy news cycles and flashy bulletins.

The gloomy figures keep coming and are bound to mesmerise.  The ICRC makes an assessment that the numbers of armed conflicts globally hovers around 120, involving 60 states and 120 non-state entities.  The post-Cold War environment has seen fertile grounds for this increase in number.  Since 2000, non-international armed conflicts have burgeoned from under 30 to approximately 100.

The field is also characterised by a grand paradox, something that did not go unnoticed in comments made by the President of the ICRC, Mirjana Spoljaric Egger.  States, she argues, must interpret and apply international humanitarian law to genuinely protect civilians.  This is not as odd as it sounds, given that laws regarding war and conflict are in place, not so much to abolish the conflict but to give it a patina of restraint.  Behind drafting such rules is a dark fatalism about human tendencies, and it does not look pretty.  Such laws should not become “a tool to justify death, endless suffering and devastation.”

It is ironic that institutions such as war, in being placed in a realm of normative rules and regulations, can risk becoming more palatable, an egregious state of affairs to be tolerated rather than abandoned.

The crude mix of power politics will always see mischievous conduct and commentary on the applications of international humanitarian law.  Derogations will be justified; selective readings made.  A paper from the Permanent Observer Mission of Palestine to the United Nations delivered in Geneva on July 15, 1999, for instance, observed that Israel “refuses to accept the de jure applicability of the 4th Geneva Convention to the Occupied Palestinian Territory, including Jerusalem and has committed serious violations of every relative provision of the Convention.”  UN resolutions condemning Israeli violations of the Fourth Convention had been many, and the occupation was “unique because of the multiplicity and intensity of Israel’s grave breaches, and serious violations” of the Convention, causing the Palestinian civilian population enormous suffering and representing “systematic and even institutionalized violations of international law.”

With full throated brutality, these breaches have merely increased with their intensity since October 7, with the attacks by Hamas being used as the pretext to inflict forms of suffering that would have made the drafters of the Conventions blanch.  Instead of seeing the Geneva Conventions as more relevant than ever, insidious naysaying about their continued applicability can be found.

Mukesh Kapila, a former UN official and currently professor emeritus in global health and humanitarian affairs at the University of Manchester, is an example of this unfortunate flourishing, erroneously claiming that the current “new-style warriors were unknown when the Geneva Conventions emerged over a century ago.”  He uses that irritatingly bureaucratic term “whole-of-society conflicts” – the very same the Fourth Convention was intended to address – as if it were novel, featuring “unarmed, non-uniformed combatants,” belligerents not at the “physical frontlines,” directing drones or unleashing “destructive computer viruses”.  Such a reading is almost dotty in missing the point.

Thankfully, Ellen Policinski, a legal advisor for the ICRC, notes the trend with caustic salience, and turns her nose up at it.  Conflicts and circumstances in war presented as lacking “historical antecedents” were exactly those that international humanitarian law, “including the Geneva Conventions,” were intended to regulate.  The Second World War offered the expansive, bloody template for the drafters, from genocide to the use of human shields, sexual warfare and mass starvation.  And those behind the documents, being a gaggle of soldiers, diplomats and humanitarians, acknowledged “the horrific realities of war which have not fundamentally changed.”

Better, it would seem, a world with the Geneva Conventions than one without them.  To regard derogations from their text as a sign of irrelevance and inapplicability would be tantamount to claiming that any domestic law punishing murder was inconsequential and obsolete for not preventing homicide.  What is needed, Policinski reminds us, “is not more or different rules” but “better respect for existing rules, something all states have a stake in.”FacebookTwitter

Following US’ Protectionist Policies, Canada is Shooting Itself in the Foot

On the political stage, Canada often seems to trail behind the US. After the US government’s announcement in May of imposing high tariffs on Chinese electric vehicles (EV) and steel, the Canadian government has now decided to follow suit.

On Monday, Canadian Prime Minister Justin Trudeau said Ottawa would impose a 100 percent tariff on imports of Chinese EVs and announced a 25 percent tariff on imported steel and aluminum from China. These measures align with the tariffs set by the US.

Zhou Rongyao, director of the Canadian Studies Center at the Academy of Social Sciences, told the Global Times that the recent imposition of tariffs is simply a way for Canada to demonstrate loyalty to the US, as it follows in the footsteps of the US, cheering on American decisions along the way.

Li Haidong, a professor at the China Foreign Affairs University, believes that Canada lacks independence in its foreign and security policies, particularly when it comes to its policies toward China, as Canada almost blindly follows the US. However, Canadian political elites are not sensitive to this issue; instead, they hold onto their inherent alliance mind-set and a sense of arrogant self-righteousness, willingly acting as followers of the US.

Canada’s imposition of tariffs on China has drawn a response from the spokesperson of the Chinese Embassy in Canada. The spokesperson stated this move is typical trade protectionism and a politically motivated decision, which violates WTO rules.

Canada should take a look at what the US has gained by repeatedly wielding the tariff stick against China. In an op-ed entitled “The US protectionist craze hasn’t done its economy any favors,” David Dodwell, CEO of the trade policy and international relations consultancy Strategic Access, pointed out that the US tariffs on China have not only cost the US economy dearly, but have failed in its overall objective to reduce the US trade deficit with China. Currently, the US Trade Representative’s office has received over 1,100 public comments, with many US manufacturers expressing opposition to imposing tariffs on Chinese imports, indicating that the US tariff measures are not popular.

Canada’s lack of rationality is also evident in its disregard for the voices of its own people. Liu Dan, a researcher at the Center for Regional Country Studies at Guangdong University of Foreign Studies, said that there were already voices of doubt within Canada when discussions began on whether to impose tariffs on China. This move is also inconsistent with Canada’s long-standing advocacy for proactive climate governance. Undoubtedly, this will increase burdens for Canadian businesses and consumers.

Clean Energy Canada, a Canadian clean energy think tank, criticized Ottawa’s decision, stating that Canada’s tariffs on Chinese EVs undermine affordability and the country’s climate goals. It can be said that Canada’s blind increase in tariffs will disrupt normal economic and trade cooperation between China and Canada, harm the interests of Canadian consumers and businesses, hinder Canada’s green transition, and impede global efforts to combat climate change, ultimately shooting itself in the foot.

China is Canada’s second-largest trading partner, and the two economies are interconnected. Any disruption to this vital economic relationship through political means would be regrettable and detrimental to the Canadian economy. The US has seen the consequences of its trade protectionism as “cure-all,” and it has backfired. If Canada continues to be “held hostage” by US’ unhealthy policies, it will only create more barriers to free market circulation, leading to deeper negative impacts and unforeseen shocks on the domestic economy. When considering its own interests, Canada should maintain strategic clarity and prioritize the development of its own economy, rather than succumbing to pressure from the US.

Bubbling, frothing and sloshing: Long-hypothesized plasma instabilities finally observed



Results could aid understanding of how black holes produce vast intergalactic jets

Whether between galaxies or within doughnut-shaped fusion devices known as tokamaks, the electrically charged fourth state of matter known as plasma regularly encounters powerful magnetic fields, changing shape and sloshing in space. Now, a new measurement technique using protons, subatomic particles that form the nuclei of atoms, has captured details of this sloshing for the first time, potentially providing insight into the formation of enormous plasma jets that stretch between the stars.

Scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) created detailed pictures of a magnetic field bending outward because of the pressure created by expanding plasma. As the plasma pushed on the magnetic field, bubbling and frothing known as magneto-Rayleigh Taylor instabilities arose at the boundaries, creating structures resembling columns and mushrooms.

Then, as the plasma’s energy diminished, the magnetic field lines snapped back into their original positions. As a result, the plasma was compressed into a straight structure resembling the jets of plasma that can stream from ultra-dense dead stars known as black holes and extend for distances many times the size of a galaxy. The results suggest that those jets, whose causes remain a mystery, could be formed by the same compressing magnetic fields observed in this research.

“When we did the experiment and analyzed the data, we discovered we had something big,” said Sophia Malko, a PPPL staff research physicist and lead scientist on the paper. “Observing magneto-Rayleigh Taylor instabilities arising from the interaction of plasma and magnetic fields had long been thought to occur but had never been directly observed until now. This observation helps confirm that this instability occurs when expanding plasma meets magnetic fields. We didn’t know that our diagnostics would have that kind of precision. Our whole team is thrilled!”

“These experiments show that magnetic fields are very important for the formation of plasma jets,” said Will Fox, a PPPL research physicist and principal investigator of the research reported in Physical Review Research. “Now that we might have insight into what generates these jets, we could, in theory, study giant astrophysical jets and learn something about black holes.”

PPPL has world-renowned expertise in developing and building diagnostics, sensors that measure properties like density and temperature in plasma in a range of conditions. This achievement is one of several in recent years that illustrates how the Lab is advancing measurement innovation in plasma physics.

Using a new technique to produce unprecedented detail

The team improved a measurement technique known as proton radiography by creating a new variation for this experiment that would allow for extremely precise measurements. To create the plasma, the team shone a powerful laser at a small disk of plastic. To produce protons, they shone 20 lasers at a capsule containing fuel made of varieties of hydrogen and helium atoms. As the fuel heated up, fusion reactions occurred and produced a burst of both protons and intense light known as X-rays.

The team also installed a sheet of mesh with tiny holes near the capsule. As the protons flowed through the mesh, the outpouring was separated into small, separate beams that were bent because of the surrounding magnetic fields. By comparing the distorted mesh image to an undistorted image produced by X-rays, the team could understand how the magnetic fields were pushed around by the expanding plasma, leading to whirl-like instabilities at the edges.

“Our experiment was unique because we could directly see the magnetic field changing over time,” Fox said. “We could directly observe how the field gets pushed out and responds to the plasma in a type of tug of war.”

Diversifying a research portfolio

The findings exemplify how PPPL is expanding its focus to include research focused on high energy density (HED) plasma. Such plasmas, like the one created in this experiment’s fuel capsule, are hotter and denser than those used in fusion experiments. “HED plasma is an exciting area of growth for plasma physics,” Fox said. “This work is part of PPPL’s efforts to advance this field. The results show how the Laboratory can create advanced diagnostics to give us new insights into this type of plasma, which can be used in laser fusion devices, as well as in techniques that use HED plasma to create radiation for microelectronics manufacturing.”

“PPPL has an enormous amount of knowledge and experience in magnetized plasmas that can contribute to the field of laser-produced HED plasmas and help make significant contributions,” Fox said.

“HED science is complex, fascinating and key to understanding a wide range of phenomena,” said Laura Berzak Hopkins, PPPL’s associate laboratory director for strategy and partnerships and deputy chief research officer. “It’s incredibly challenging to both generate these conditions in a controlled manner and develop advanced diagnostics for precision measurements. These exciting results demonstrate the impact of integrating PPPL’s breadth of technical expertise with innovative approaches.”

More experiments and better simulations

The researchers plan to work on future experiments that will help improve models of expanding plasma. “Scientists have assumed that in these situations, density and magnetism vary directly, but it turns out that that’s not true,” Malko said.

“Now that we have measured these instabilities very accurately, we have the information we need to improve our models and potentially simulate and understand astrophysical jets to a higher degree than before,” Malko said. “It’s interesting that humans can make something in a laboratory that usually exists in space.”

Collaborators included researchers from the University of California-Los Angeles, the Sorbonne University, Princeton University and the University of Michigan. The research was funded by the DOE’s Laboratory-Directed Research and Development program under contract number DE-AC02-09CH11466. The experiment was conducted using the University of Rochester’s Omega Laser Facility under DOE/National Nuclear Security Administration contract number DE-NA0003856.

PPPL is mastering the art of using plasma — the fourth state of matter — to solve some of the world's toughest science and technology challenges. Nestled on Princeton University’s Forrestal Campus in Plainsboro, New Jersey, our research ignites innovation in a range of applications, including fusion energy, nanoscale fabrication, quantum materials and devices, and sustainability science. The University manages the Laboratory for the U.S. Department of Energy’s Office of Science, which is the nation’s single largest supporter of basic research in the physical sciences.

How smart toys spy on kids: What parents need to know

Smart Toys

Toniebox, Tiptoi, and Tamagotchi are smart toys, offering interactive play through software and internet access. However, many of these toys raise privacy concerns, and some even collect extensive behavioral data about children, report researchers at the University of Basel, Switzerland.

The Toniebox and the figurines it comes with are especially popular with small children. They’re much easier to use than standard music players, allowing kids to turn on music and audio content themselves whenever they want. All a child has to do is place a plastic version of Peppa Pig onto the box and the story starts to play. When the child wants to stop the story, they simply remove the figurine. To rewind and fast-forward, the child can tilt the box to the left or right, respectively.

A lot of parents are probably thinking, “Fantastic concept!” Not so fast – the Toniebox records exactly when it is activated and by which figurine, when the child stops playback, and to which spot they rewind or fast-forward. Then it sends the data to the manufacturer.

The Toniebox is one of twelve smart toys studied by researchers headed by Professor Isabel Wagner of the Department of Mathematics and Computer Science at the University of Basel. These included well-known toys like the Tiptoi smart pen, the Edurino learning app, and the Tamagotchi virtual pet as well as the Toniebox. The researchers also studied less well-known products like the Moorebot, a mobile robot with a camera and microphone, and Kidibuzz, a smartphone for kids with parental controls.

One focus of the analysis was security: is data traffic encrypted, and how well? The researchers also investigated data protection, transparency (how easy it is for users to find out what data is collected), and compliance with the EU General Data Protection Regulation. Wagner and her colleagues are presenting their results at the Annual Privacy Forum (https://privacyforum.eu/) in early September. Springer publishes all the conference contributions in the series Privacy Technologies and Policy.

Collect data while offline, send it while online

Neither the Toniebox nor the Tiptoi pen come out well with respect to security, as they do not securely encrypt data traffic. The two toys differ with regard to privacy concerns, though: While the Toniebox does collect data and send it to the manufacturer, the Tiptoi pen does not record how and when a child uses it.

Even if the Toniebox were operated offline and only temporarily connected to the internet while downloading new audio content, the device could store collected data locally and transmit it to the manufacturer at the next opportunity, Wagner surmises. “In another toy we’re currently studying that integrates ChatGPT, we’re seeing that log data regularly vanishes.” The system is probably set up to delete the local copy of transmitted data to optimize internal storage use, Wagner says.

Companies often claim the collected data helps them optimize their devices. Yet it is far from obvious to users what purpose this data could serve. “The apps bundled with some of these toys demand entirely unnecessary access rights, such as to a smartphone’s location or microphone,” says the researcher. The ChatGPT toy still being analyzed also transmits a data stream that looks like audio. Perhaps the company wants to optimize speech recognition for children’s voices, the Professor of Cyber Security speculates.

A data protection label

“Children’s privacy requires special protection,” emphasizes Julika Feldbusch, first author of the study. She argues that toy manufacturers should place greater weight on privacy and on the security of their products than they currently do in light of their young target audience.

The researchers recommend that compliance with security and data protection standards be identified by a label on the packaging, similar to nutritional information on food items. Currently, it’s too difficult for parents to assess the security risks that smart toys pose to their children.

“We’re already seeing signs of a two-tier society when it comes to privacy protection for children,” says Feldbusch. “Well-informed parents engage with the issue and can choose toys that do not create behavioral profiles of their children. But many lack the technical knowledge or don’t have time to think about this stuff in detail.”

You could argue that individual children probably won’t experience negative consequences due to toy manufacturers creating profiles of them, says Wagner. “But nobody really knows that for sure. For example, constant surveillance can have negative effects on personal development.”

Several of the twelve smart toys examined in the study raise privacy concerns.

How beetle juice led to the discovery of a virus and solved the mystery of a superworm die-off

Rutgers University-New Brunswick scientists have discovered a virus that caused a nationwide die-off of superworms, a common food for birds, reptiles, other pets and, more and more so, even for humans as an alternative protein source. In doing so, they pioneered a different way to search for and identify emerging viruses and pathogens in humans, plants and animals.

Using chopped up beetle carcasses forming a slurry and an electron microscope cooled by liquid nitrogen, the scientists reported today in Cell that they have discovered what they have titled Zophobas morio black wasting virus. The name is derived from the virus’ deadly effect on a species of darkling beetle, Zophobas morio, native to the subtropics, particularly in the insect’s immature larval stage when it emerges from its eggs as large, brown superworms. This species was named “superworm” because its larvae are bigger, at about 2 inches in length, than any others grown as feed.

The protein-rich larvae of Z. morio, which are dietary staples for captive, often exotic reptiles, birds, fish and amphibians worldwide, mysteriously began dying off in 2019, puzzling pet food suppliers and pet owners.

Jason Kaelber, an author of the study and an associate research professor at the Institute for Quantitative Biomedicine (IQB) at Rutgers-New Brunswick, worked with Judit Penzes, the first author of the study and a postdoctoral associate at IQB.

“Judit was looking to identify the reason beetle farmers were losing all their superworm colonies to a deadly disease and I was looking to develop ways of discovering new viruses that don’t depend on DNA or RNA sequencing,” Kaelber said. “We ended up discovering the virus that has been sweeping the country and killing superworms.”

The scientific investigation began more than a year ago, when Penzes, a molecular virologist, was contacted by beetle farm owners whose superworms were mysteriously dying off at alarming rates. Penzes was already well known in the industry because of earlier work where she isolated a virus that was killing crickets, another popular food for pets.

She started by collecting superworms at pet stores in New Jersey. “Whenever I went to a pet store, I immediately went to the feeder insect section, opened the containers and looked at the worms,” she said. “They were all infected. I told the owners of the stores what I was seeing that I was researching this virus, and asked if I could have the container. They were immediately on board. They told me to take as many as I needed.”

She returned to her lab, took a Magic Bullet blender, dropped the worm carcasses in and blended them at a high speed. The process created a slurry of beetle juice which she took and processed using a virus purification method that separates the virus out due to its density. In the final step, she shined a fluorescent light on the centrifuge tube and the virus glowed blue.

“I said, ‘I got you,’ when I saw it,” Penzes said. “I knew then it was, indeed, a virus.”

Next, Penzes worked with Kaelber, a fellow electron microscopist, to examine the virus using a cryo-electron microscope, which allows a three-dimensional view of the virus, including its interior.

“You’re taking a virus, a protein, a cell, etc., and you’re freezing it so quickly that the water solidifies without turning into ice crystals,” Kaelber said. “We actually can figure out what the amino acid sequence of the protein is without analyzing the DNA, and just by looking at that 3D structure, because we have such sharp resolution.”

They compared the structure of the protein with all known proteins using the database of the Protein Data Bank hosted at Rutgers and found that it is similar to a virus affecting cockroaches, but not identical, and part of a family of animal viruses known as parvoviruses.

“It’s a new one, different from anything that’s been sequenced or imaged before,” Penzes said.

The scientists are also grateful to superworm farmers nationwide who sent samples voluntarily, once word of the study got out. “The eagerness of the farmers to help us out researching the virus had an enormous role in helping this published study to be born,” Penzes said.

The effort, Kaelber said, provided a “proof of concept” that cryo-electron microscopy can be employed to directly discover and characterize new pathogens.

“In the future, if there’s ever a really important outbreak, we're going to want to throw every tool we can at it to see what we can find,” Kaelber said. “We’d like to make diagnostic cryo-electron microscopy routinized, so that when there’s some unknown infectious disease, we have a lot of options for same-day identification of the causative agent.”

Cryo-electron microscopy has gained popularity in recent years, becoming a more prevalent method for 3D analysis of known specimens. However, the Rutgers work represents the first time the method was used on an unknown pathogen.

After discovering the virus, the researchers tested a way to protect the Z. morio beetles from disease, by injecting a closely related virus from another species that doesn't cause symptoms. They are developing a vaccine based on that work.

“The discovery is important for two reasons,” Kaelber said. “First, beetle farmers can use this information to protect their colonies and understand which actions will be effective or ineffective at managing the epidemic. Second, the beetle epidemic was a real-world test of the technology that we hope can be useful to rapidly investigate future outbreaks in humans, plants or animals.”

Scientists Martin Holm of the Rutgers Institute for Quantitative Biomedicine and Samantha Yost of REGENXBIO Inc., in Rockville, Md., also authored the study.

Rain or shine? How rainfall impacts size of sea turtle hatchlings



Study reveals how local weather influences hatchling development across 37 beaches worldwide

Female sea turtles lay their eggs, cover the nest with sand and then return to the ocean, leaving them to develop and hatch on their own. From nest predators to rising temperatures, odds of survival are bleak. Once hatched and in the ocean, about one in 1,000 make it to adulthood.

Hatchling size matters. Larger hatchlings, which move faster, are more likely to survive because they spend less time on risky beach sands.

Research shows that both air and sand temperatures crucially impact sea turtle hatchlings. Cooler temperatures produce larger, heavier hatchlings with more males, while warmer temperatures accelerate hatching and offer predator protection. For endangered loggerhead (Caretta caretta) and green (Chelonia mydas) sea turtles, cooler and moister conditions result in stronger hatchlings. However, rising temperatures might shorten incubation periods, and erratic rainfall can disrupt growth, potentially affecting survival.

Balancing temperature and moisture is vital for the health of these vulnerable sea turtles. Too much moisture can be deadly for embryos.

An internationally collaborative study by Florida Atlantic University and led by the University of Tübingen in Germany, delves into how fluctuating rainfall impacts the development of sea turtle hatchlings, revealing that it has a more profound effect than changes in air temperature.

The research, which spans data from 37 beaches worldwide – a longitudinal study in Florida, and experimental studies on the Cape Verde Islands – shows that precipitation plays a crucial role in determining hatchling body size. Rainfall cools the beach surface and enhances the moisture needed for egg development, making it a better predictor of body size than temperature.

Results of the study, published in BMC Ecology and Evolution, reveal that the impact of rainfall varies between species. For loggerhead turtles, heavier rainfall results in hatchlings with smaller carapaces (shell) but greater weight, while green turtle hatchlings grow smaller carapaces without a change in body mass.

“Findings from our study highlight the need for more localized data on how regional weather influences incubation and hatchling development,” said Jeanette Wyneken, Ph.D., co-author and professor, Department of Biological Sciences, FAU Charles E. Schmidt College of Science. “These data are essential for refining conservation strategies to protect sea turtles amidst global warming.”

The study started with data from Boca Raton, comparing hatchling size (length, width, and mass) with local climate factors.  Next, data were collected from 19 beaches with loggerhead hatchlings and 17 beaches with green turtle hatchlings. A third part of the study looked at hatchlings in Cabo Verde after a few days of rain during their dry season to see how precipitation affected their size.

In the Mediterranean, particularly on the beaches of Cyprus and Turkey, the dry season brings very little rain from the North Atlantic. For green turtles in these drier areas, the effects of precipitation become noticeable only after the dry season ends. In Florida, however, precipitation levels stay fairly consistent throughout the nesting season due to local weather patterns, though droughts and heatwaves typically occur in July and October.

“It's not clear exactly how rain affects hatchling size,” said Wyneken. “One idea is that rain cools the nests, which can change the temperature and impact the sex ratio of the hatchlings. This could lead to differences in hatchling size and shape, similar to how male and female hatchlings of other turtles, like the giant river turtle, have different shell shapes.”

As climate change shifts rainfall patterns – making wet areas wetter and dry areas drier – the impact on sea turtle nesting sites suggests that global conservation strategies for loggerhead and green sea turtles likely need to be updated.

“Effective management units for conservation should focus on regularly updating and including important nesting sites, highlighting the importance of local conservation efforts,” said Wyneken. “Analyzing local data from various nesting sites is crucial for understanding sea turtle nesting patterns. These local databases should be made more accessible and widely shared to improve our knowledge and support local conservation efforts.”
