Addressing Environmental Challenges in a Divided World

On August 14, a weary UN representative walked into the main venue after long discussions and little sleep, witnessing the fading hopes for a global treaty on plastic pollution.

The two-week conference in Geneva, Switzerland, marked his second attempt to create international regulations to tackle this pressing issue.

However, just before a resolution, disagreements emerged over whether the treaty should contain provisions for boosting recycling rates, as well as targets to decrease plastic production at its source.

Oil Production Status – As demand for gasoline and diesel diminishes, the reliance on the plastics industry for revenue complicates efforts to reduce production.

The treaty required unanimous consent to be enacted, but some states stood firm on their “red lines,” leading to a breakdown in talks.

Does this scenario ring a bell? The Environmental Summit often experiences the collapse of protracted negotiations, lengthy discussions, and debates. Even when agreements are reached, consultations typically yield minimal concrete outcomes, a pattern seen during the 2023 COP28 Summit in Dubai.

A significant challenge lies in the longstanding expectation of unanimous agreement, as noted by Robert Faulkner from the London School of Economics. He explains that the United Nations has initiated discussions related to climate change and biodiversity, which requires consensus from hundreds of countries with diverse economic and political contexts.

“The consensus approach in international environmental negotiations has consistently been the Achilles’ heel of the United Nations’ environmental efforts,” states Faulkner. “This often results in compromises that reflect the lowest common denominator.”

Activists and strategists are growing weary from a series of stagnant climate summits, with slowed progress in efforts to halt biodiversity loss. In light of the recent crisis in Geneva, there’s increasing skepticism regarding the environmental diplomatic process.

“Why do we believe that environmental challenges can only be addressed through multilateralism and consensus among over 190 countries? That approach seems ineffective,” says Simon Sharp, a former British diplomat and author of Five Times Faster: Rethinking the Science, Economics, and Diplomacy of Climate Change.

More activists and strategists are seeking alternative strategies. Sharp, who played a role in organizing the COP26 Climate Summit in Glasgow, UK, emphasizes the need to prioritize action over targets and to rally influential countries to expedite decarbonization by sector. “If you want meaningful change, you must take action,” he asserts.

Eirik Lindebjerg, from the WWF Campaign Group, echoes a similar sentiment in Norway. “If 100 countries agree to implement measures to phase out fossil fuel vehicles, even without participation from other nations, it can still yield significant climate benefits,” he argues. “To me, there is a compelling case to move beyond the consensus mindset.”

This approach draws inspiration from positive “turning points” aimed at steering the world toward rapid decarbonization in various sectors, such as transportation and electricity.

Tim Renton, an author and academic at the University of Exeter, UK, argues in his upcoming book Positive Turning Points: How to Fix the Climate Crisis that collaboration among smaller groups of countries could prove more effective than relying solely on consensus-based negotiations.

“The essence of a tipping point is that a minority can ultimately sway the majority,” he explains. “Thus, it is illogical to restrict progress by demanding universal agreement before any actions are taken.”

Of course, this strategy hinges on engaging the most influential countries (those with economies capable of pushing these turning points). Given the unpredictability of US leadership under Donald Trump, this remains uncertain.

Yet, there are indications that this way of thinking is gaining traction within diplomatic circles. For instance, the Brazilian hosts of the forthcoming COP30 Climate Summit are contemplating a reorganization of frameworks that could enable the new UN Council for Climate Change to enact majority votes and facilitate direct, sector-specific collaboration among nations. Simultaneously, many observers are viewing China’s increasing engagement in climate matters as an opportunity for them to take a leadership role on specific issues like renewable energy and electric vehicles.

When progress in environmental policy is predominantly driven by small groups of nations, one must question the relevance of large agreements like climate summits. Events of this nature can aid in “norm-setting,” remarks Sharp, facilitating recognition of ongoing transitions, such as the global shift away from coal reliance. However, they shouldn’t be expected to lead the charge for change, he cautions.

There is no denying that decades-long efforts have been instrumental in fostering international consensus on environmental strategies. Nevertheless, consensus-driven negotiations can move at the pace of the slowest participants in the dialogue. As the world confronts a multifaceted crisis involving climate change, biodiversity, and pollution, it may be time to reconsider such an approach.

Applying Limestone on the Farm Could Lead to Surprising Environmental Benefits

Farmers apply lime to pastures to enhance soil quality

Wayne Hutchinson/Alamy

The centuries-old method of distributing crushed limestone on farmland can enhance crop yields by lowering soil acidity. While this practice is typically viewed as a contributor to greenhouse gas emissions, recent studies indicate that “liming” might actually assist in sequestering substantial amounts of carbon dioxide from the atmosphere.

“Liming can either act as a carbon source or as a carbon sink. Empirical evidence suggests it serves as a fairly effective carbon sink,” says Noah Pranabsky from Yale University. This revelation could motivate the global spread of limestone on farms, although liming does not produce this effect universally.

Each year, millions of tons of crushed limestone spread across fields are classified as emission sources. This classification arises because when alkaline materials dissolve in acidic soils, a significant portion of its carbon is released as CO2. However, this assessment is not entirely accurate. According to Tim Jesper Souhoff, also from Yale, the situation is more complex.

Today’s soils are highly acidic, resulting from extensive fertilizer use and pollution from fossil fuel combustion. Consequently, various other alkaline minerals in the soil dissolve and liberate carbon, even in the absence of limestone. “These CO2 emissions will happen regardless of whether lime is added or not,” Suhrhoff explains, emphasizing that this alteration of acidity can lead to unintentional consequences.

Suhrhoff advocates for a more accurate evaluation of emissions from this practice, suggesting that scientists should analyze CO2 emitted versus captured in scenarios both with and without liming.

As an illustration of this method, Suhrhoff, Planavsky, and their team focused on the Mississippi River basin, a region that gathers runoff from the majority of U.S. farmland. They calculated the net carbon impact of limestone applications from 1900 to 2015 across the area.

The researchers estimated emissions from the soil while utilizing geochemical models to assess how liming alters soil acidity. They also compared their model results with direct observations of alkalinity in the Mississippi, where limestone reacts with carbon dioxide.

By employing their innovative approach, the researchers determined that they had sequestered around 300 million tonnes of CO2 in the region, rather than enabling the release of hundreds of millions of tonnes of emissions. Souhoff presented these findings at the Goldschmidt Conference held in Prague, Czech Republic, on July 10th.

This practice can also be coupled with the increased use of crushed volcanic rocks on farmland to sequester even more CO2 from the atmosphere.

Wolfram Buss from the Australian National University suggests that while liming can act as a carbon sink, the success seen in the Mississippi River Basin may not apply universally. “There is a potential risk with lime application, which could result in net CO2 emissions in other systems, primarily due to the significant acidification of agricultural soils,” he warns.

The subsequent step is to determine where liming is most essential. “This presents the opportunity for us to foster improved crop yields, potentially leading to billions of tons of CO2 removal,” Planavsky remarks. Financial incentives can significantly aid low-income farmers who are unable to afford the optimal amount of lime needed for their crops.

Have You Discovered an Unexpected Solution to the Environmental Impact of Air Travel?

Will it take flight? This question is increasingly raised by those mindful of the environment. Boarding a plane might seem like the only realistic choice, especially during hard times or when loved ones live far away.

We can certainly engage in some air travel as part of a sustainable future, but we must first dispel certain misconceptions and clearly outline feasible ways to lessen our global warming footprint.

The most common myth is that sustainable aviation fuels (SAFs) can resolve our issues. This label is misleading, as SAFs often don’t live up to their name.

Here’s why: there are three primary categories of SAF. The first type is derived from waste, particularly used cooking oil. However, this only accounts for about 2-3% of global flights. The second type consists of synthetic SAFs produced from raw materials like captured carbon dioxide, using renewable energy. The efficiency of these processes is quite low (at least 2 kilowatt-hours of energy are needed to generate 1 kWh of fuel), which is a misguided use of limited renewable resources. The third type is made from crops, which puts immense pressure on farmland and the food system, posing major challenges. In reality, sustainable aviation fuel is not the revolutionary solution many hope for.

Another hopeful concept I often encounter is the idea that electrification or hydrogen fuel could decarbonize aviation. However, electrification is practical only for short-haul flights; battery weight makes it unfeasible for long distances. Hydrogen poses its own challenges due to its bulky storage requirements, even when compressed to 700 times atmospheric pressure.

On a brighter note, there are significant opportunities that haven’t garnered enough attention.

Potential solutions for greener aviation have been overlooked until recently. The high, wispy trails produced by aircraft exhaust – which account for over 60% of the climate impact of flights – carry even more weight when considering their short-term influence over the next two decades.

These contrails reflect Earth’s heat back into the atmosphere and function somewhat like a blanket. However, their overall impact is complex. They can not only trap heat but also reflect sunlight on clear days, creating a cooling effect that mainly occurs during the day, particularly over dark surfaces like oceans. Unfortunately, the warming effect tends to dominate during warm nights over dark surfaces.

By making small adjustments to flight paths, we can manage contrail formation. Changing an aircraft’s altitude or trajectory in specific weather conditions can be beneficial. Deliberate modifications while flying over sunny waters could yield positive results. A slight alteration in flight routes—just 1.7%—could potentially reduce contrail warming impacts by almost 60%. Real-time modeling is essential for integrating this into flight planning, similar to current practices for avoiding storms and managing air traffic.

This presents a relatively cost-effective solution that requires industry leadership. Once contrail management becomes established, the role of SAF might shift significantly, allowing it to contribute to cleaner burning and mitigate the worst impacts of contrails on more challenging flights.

Does this imply we can ignore the climate ramifications of flying? Unfortunately, no. Yet, understanding these factors provides a legitimate reason for optimism.

The Most Ineffective ChatGPT Prompts for Environmental Research, According to Studies

Each time I interact with ChatGPT, I consume energy—what does that really mean? A new study has highlighted the environmental costs of using large-scale language models (LLMs) and provided insights on how users can minimize their carbon footprints.

German researchers evaluated 14 open-source LLMs, ranging from 14 to 72 billion parameters, administering 1,000 benchmark questions to assess the CO2 emissions generated in response to each.

They discovered that utilizing internal reasoning to formulate answers can result in emissions up to 50 times greater than those generated by a brief response.

Conversely, models with a higher number of parameters—typically more accurate—also emit more carbon.

Nonetheless, the model isn’t the only factor; user interaction plays a significant role as well.

“When people use friendly phrases like ‘please’ and ‘thank you,’ LLMs tend to generate longer answers,” explained Maximilian Dorner, a researcher from Hochschule München Applied Sciences University and the lead author of the study, to BBC Science Focus.

“This results in the production of more words, which leads to longer processing times for the model.

The extra words don’t enhance the utility of the answer, yet they significantly increase the environmental impact.

“Whether the model generates 10,000 words of highly useful content or 10,000 words of gibberish, the emissions remain the same,” said Dorner.

Being polite to an AI platform uses more power – Getty

This indicates that users can help reduce emissions by encouraging succinct responses from AI models, such as asking for bullet points instead of detailed paragraphs. Casual requests for images, jokes, or essays when unnecessary can also contribute to climate costs.

The study revealed that questions demanding more in-depth reasoning—like topics in philosophy or abstract algebra—yield significantly higher emissions compared to simpler subjects like history.

Researchers tested smaller models that could operate locally, yet Dorner noted that larger models like ChatGPT, which possess more than 10 times the parameters, likely exhibit even worse patterns of energy consumption.

“The primary difference between the models I evaluated and those powering Microsoft Copilot or ChatGPT is the parameter count,” Dorner stated. These commonly used models have nearly tenfold the parameters, which equates to a tenfold rise in CO2 emissions.

Dorner encourages not only individual users to be mindful but also highlights that organizations behind LLMs have a role to play. For instance, he suggests that they could mitigate unnecessary emissions by creating systems that select the smallest model necessary for accurately answering each question.

“I’m a big supporter of these tools,” he remarked. “I utilize them daily. The key is to engage with them concisely and understand the implications.”

EPA initiates staff reductions for environmental justice workers

The Environmental Protection Agency has initiated significant staffing changes by beginning the process of reducing hundreds of staff through a “power reduction” process.

Last month, the agency announced a large-scale rollback of environmental regulations, including key components of the Clean Air Act, with administrator Lieseldin vowing to undermine the fight against climate change.

In February, the EPA placed environmental justice staff on administrative leave and terminated some probationary workers. Many employees are now working remotely or engaging in telework.

The latest action by the agency involves the beginning of the termination process for around 280 workers who were involved in environmental justice and diversity, equity, and inclusive programs. Additionally, 175 EPA employees have been reassigned to new roles.

“Today, the EPA has informed employees focusing on diversity, equity, and inclusion and environmental justice of the agency’s necessity to reduce personnel through the handbook and federal regulations governing the RIF procedure,” said EPA spokesperson Molly Vaseliou in an email statement. “Certain employees have also been notified of their reassignment to different offices as part of this process.”

NBC News has obtained a memorandum sent to employees affected by the power reduction, indicating that the reduced staffing levels at the EPA will come into effect on July 31st.

“President Trump’s election was a call to action from the American people, which includes issuing executive orders for significant changes within the federal bureaucracy to benefit American families, workers, taxpayers, and the government as a whole,” the memorandum explains. “We appreciate your understanding and cooperation during this transitional period.”

The Unintended Environmental Impact of Trump’s Policies on Online Shopping Emissions

Fashion giants like Shein and Temu have seen significant growth in the US due to tariff exemptions that kept prices low for packages shipped from China.

President Trump has ordered the closure of these loopholes starting with packages from China-Hong Kong, potentially impacting airline emissions related to the fashion industry.

Last year, 1.36 billion packages entered the US through this loophole, mostly from China. This exemption allows items under $800 to enter without customs duty, leading to a rise in emissions from shipping packages by air.

Flying packages across the ocean is 68x more carbon-intensive than marine cargo transport, according to Climate Action Accelerator.

In many countries, freight below a certain value is exempt from taxes. The US set the minimum exemption at $800, allowing foreign e-commerce platforms to compete with domestic retailers like Amazon.

This exemption helped Shein establish a niche in the US market with affordable apparel. However, President Biden announced a crackdown on these imports citing various concerns.

The number of shipments to the US has increased significantly, leading to environmental concerns and the need for stricter regulations.

President Trump took steps to end the De Minimis exemption, aiming to impose taxes on packages from Hong Kong and mainland China.

New rules will phase out exemptions over the next few weeks, with steep taxation coming into effect on June 1st. This move is expected to impact air ticket emissions significantly.

The increase in air freight usage has led to a rise in greenhouse gas emissions. Efforts to reduce emissions in this sector are minimal, posing a challenge for sustainability initiatives.

Shein and Temu did not respond to requests for comment regarding the new regulations.

Trump’s actions to close the loophole in February resulted in declining sales for Shein and Temu, indicating potential shifts in e-commerce practices.

Companies might opt for larger cargo shipments using marine transport to avoid high tariffs and reduce emissions, a change that could impact the industry significantly.

The increase in Antarctic tourism has brought economic benefits to Ushuaia in Argentina but has also raised concerns about environmental impact.

Coal plants ranked as the worst offenders in pursuit of environmental exemptions

The country’s most polluted coal burning power plant has called on President Trump to exempt it from stricter restrictions on dangerous air pollution after the administration recently invited businesses to apply for presidential pollution exemptions via email.

Aging Corstrip power plants in Corstrip, Montana release more harmful particulate matter contamination or soot than any other power plant in the country, the Environmental Protection Agency. The diagram is shown. The new rules adopted by the Biden administration in 2023 would have forced facilities to install new equipment because they lack modern pollution prevention, the country’s only coal plant.

The Colstrip Factory is currently applying for a two-year exemption from these rules, according to the Montana Legislature delegation that backed the request.

The new pollution standards “have at stake the economic viability of plants that will damage the local electrical grid if closed,” Sen. Steve Daines and other members of the delegation wrote in a letter sent Monday to EPA administrator Lee Zeldin. “Without the corstrip, consumers will bear a burden of higher energy costs and grid reliability, and their closure will hinder economic development in the region.”

Health experts pointed out that the letter does not address the health effects of fine contaminated particles. Many studies have shown that particles penetrate deep into the lungs and are small enough to enter the bloodstream, where they migrate to the heart and other organs, increasing mortality from cardiovascular and respiratory diseases.

A 2023 study showed that it emits coal-fired power plants, particularly fine particles containing sulfur dioxide. Related to higher mortality rates More than other types of pollution.

The contamination “can be extremely harmful, especially for young children with lung disease,” said Robert Merchant, a pulmonary surgeon at Billings, Mont. He said the delegation’s letters showed “complete indifference to health.”

Colstrip Plant’s stricter pollution rules exemption came after the EPA last month told businesses that they could apply for exemptions from key clean air rules by sending emails to agents. The EPA pointed to some of the Clean Air Act, which allows the president to temporarily exempt industrial facilities from the new rules if the technology necessary to meet these rules is not available, and if it is for national security.

The Trump administration has also announced its intention to roll back many of the rules completely. This could mean that plants like Corstrips ultimately do not need to meet new contamination standards.

The move was part of Zeldin’s broad efforts to guide energy and cars from its original role in environmental protection and regulation to make them more affordable.

Northwestern Energy Group and Talen Energy, which operate the factory along with other minority owners, did not immediately respond to comments.

The exemption granted by the Trump administration could face legal challenges from environmental groups. In creating the new rules, the Biden administration had identified already available technologies that would allow corstrip facilities to meet more stringent standards.

The Biden administration also estimated that new pollution prevention technology would cost much less for installations than the $500 million that the Corstrip factory said it would cost.

“These technologies are available,” said Amanda Levin, director of Policy Analysis for the Natural Resources Defense Council, an environmental advocacy group.

Research finds no evidence of environmental pollution from pre-Roman copper industry in Timna Valley

Scientists from Tel Aviv University conducted geochemical surveys at two smelting camps dating back to the 10th century BC, the time of the Biblical kings David and Solomon. Timna Valley It is located in southern Israel, in the southern Arabah. They found that environmental pollution resulting from copper production is minimal, spatially limited, and poses no danger to residents of the area, past or present.

“We toured two major copper production sites in the Timna Valley: one from the Iron Age; King Solomon's time Professor Erez Ben Yosef of Tel Aviv University said:

“Our research was very extensive. We took hundreds of soil samples from both locations for chemical analysis and created high-resolution maps of the presence of heavy metals in the area.”

“We found that contamination levels at the Timna copper mining site were very low and confined to the site of an ancient smelting furnace.”

“For example, the concentration of lead, a major pollutant in the metal industry, drops to less than 200 ppm just a few meters away from the furnace.”

“By comparison, the U.S. Environmental Protection Agency defines industrial areas as safe for workers at 1,200 ppm and residential areas as safe for children at 200 ppm.”

The new study contradicts a series of papers published since the 1990s about pollution allegedly caused by the ancient copper industry.

“We are proving that this is not true,” Professor Ben Yosef said.

“Timna's contamination is very spatially localized, with the only people probably working directly at the furnaces suffering from inhalation of toxic gases, and just a short distance away, the soil is completely destroyed. It’s safe.”

“Furthermore, the agreement in the spatial distribution of copper and lead concentrations in the soil that we found indicates that the metal is ‘locked up’ in slag and other industrial wastes, so that the metal can leach into the soil. It has no effect on plants or humans.”

“Our findings are consistent with several recent studies conducted in the Wadi Faynan region of Jordan, which also show very low levels of pollution.”

“Timna and Feynan are ideal locations for this kind of research because they are undisturbed by modern mining, as happened for example in Cyprus, and thanks to their dry climate metals in the soil are not washed away. .”

“In Feynan, scientists from Hebrew University examined the skeletons of 36 people who lived at the mining site during the Iron Age and found that only three had evidence of contamination in their teeth. The rest It was completely beautiful. We are now presenting a similar picture for Timna.”

In addition to the geochemical study, the authors also reviewed existing literature and found that the hypothesis of global pollution before Roman times lacked solid evidence.

“In the 1990s, there was a tendency to attribute ancient copper production to the first example of industrial pollution,” said Dr. Omri Jagel of Tel Aviv University.

“Such statements make headlines and attract research funding, but they unnecessarily project contemporary pollution problems into the past.”

“Furthermore, research literature tends to use the term 'contamination' to describe traces of ancient metallurgical activity, leading to the erroneous assumption that the metal industry was harmful to humanity from its earliest days. They are connected, but this is clearly false.”

“Even when metal production became large-scale and essential to human civilization, it was the toxic lead industry that caused global pollution, not necessarily other metals.”

“Studies in the 1990s argued that trace amounts of copper found in Greenland ice cores migrated through the atmosphere from places like Timna.”

“However, this claim has not been supported by subsequent research.”

“As researchers facing today's tough environmental challenges, such as climate change, we often look for similar problems in the past or think that environmental degradation is an inevitable consequence of human activity since the agricultural revolution. There is a tendency to

“But we have to be careful. We might call some slag falling on the ground 'pollution', but we can't treat this local waste as regional or global environmental pollution.” should not be confused with. ”

Environmental organizations gear up to combat incoming Trump administration

overview

  • Environmental groups are gearing up to resist the anticipated policy changes from the incoming Trump administration.
  • They foresee President Trump expanding oil and gas drilling and attempting to undo or scale back some of the legislation passed during Biden’s presidency.
  • Environmental groups are bracing for legal battles ahead and are seeking donations to support their efforts.

Environmental groups are preparing for pushback against the upcoming Trump administration, expecting swift policy changes compared to when Donald Trump took office in 2017.

Based on Trump’s past actions and recent campaign comments, experts predict that he will expand oil and gas drilling, reduce land conservation efforts, and possibly aim to reverse Biden-era legislation like the Infrastructure Investment and Jobs Act and the Curbing Inflation Act.

Environmentalists are concerned about Trump’s Cabinet picks, who are likely to support increased drilling activities as per Trump’s statements. Legal battles are on the horizon, with groups like the Center for Biological Diversity gearing up for potential fights against unlawful changes.

The Brookings Institution reported that Trump’s first administration made around 74 moves that were seen as detrimental to environmental policies, a number that might rise in the next term given Trump’s promise to change regulations significantly.

Environmental groups like NRDC and the Center for Biological Diversity are readying themselves for legal disputes and are actively seeking donations to fund their fight against expected environmental policy changes.

Trump’s transition team has not provided any comments on the matter.

Both NRDC and the Center for Biological Diversity have a track record of successfully challenging Trump’s policies in court, winning a significant percentage of the cases they engaged in.

Conservation groups are anticipating conflicts over protected federal lands, particularly in the Southwest, with past battles over Bears Ears National Monument and Grand Staircase-Escalante National Monument in Utah serving as examples of potential future clashes.

Evangelical Environmental Activists Rally for Climate Change Vote as Election Nears

overview

  • A group of young evangelical Christians is planning a campaign at religious universities to persuade students to think about climate change at the voting booth.
  • It’s part of a small movement within the evangelical community to combine Christian values with climate action.
  • The effort comes as President Donald Trump continues to court evangelical voters while calling climate change a “fraud.”

When an evangelical student group calls for a vote on climate change at a Christian university later this month, they plan to carry the tagline: “Love God, Love Your Neighbor, Vote for Climate Change!”

This is the first time the bipartisan group Young Evangelicals for Climate Action has organized such an in-person campaign on campus since its inception in 2012.

The volunteers, members of six Christian university chapters, are working to connect communities affected by the climate crisis with the Christian duty to “love our neighbor” and help those in need. We are aiming for

The effort is part of a larger movement led by the Evangelical Environmental Network, a faith-based organization calling for climate action.

Its members are a minority within the community. A 2022 poll from the Pew Research Center found that evangelical Christians are the largest minority. most likely Religious groups in the United States have expressed skepticism about anthropogenic climate change.

In the 2020 election, 84% of white evangelical Christians I voted for Donald Trump — I have voted for Trump in the past Climate change is a “hoax” decades of contradictions scientific consensus. Just last week, President Trump falsely claimed that “the Earth has actually gotten a little colder lately,” and at a September 29 rally called climate change “one of the biggest frauds in history.”

Cast of white evangelical voters third President Trump's 2016 vote count and Pew Research poll released last month We found that 82% said they would do so again this year.

Still, Jessica Morman, CEO of the Evangelical Environmental Network, says she's working to get Christians to see climate change as an issue that loves God's planet.

“As evangelicals, we have a biblical mission to care for God’s creation,” said Morman, a pastor and climate scientist. “And in the 21st century, that means taking action on the climate.”

Study Shows Environmental Threat Posed by ‘Forever Chemicals’ in Lithium-Ion Batteries

Toxic PFAS ‘forever chemicals’ used in lithium-ion batteries that are essential to the clean energy transition New research findings As the emerging industry expands, it will pose threats to the environment and human health.

The multifaceted, peer-reviewed study focused on a little-studied and unregulated subclass of PFAS called bis-FASIs, which are used in lithium-ion batteries.

Researchers have found alarming levels of chemicals in the environment near manufacturing plants and in remote locations around the world, found that they can be toxic to living organisms, and found that battery waste in landfills is a major source of contamination.

“The nation faces two important challenges — minimizing water pollution and increasing access to clean, sustainable energy — and both are worthwhile,” said Jennifer Gelfo, a researcher at Texas Tech University and co-author of the study.


“But there is a bit of a tug-of-war between the two, and this study highlights that there is now an opportunity to better incorporate environmental risk assessments as we expand our energy infrastructure,” she added.

PFAS are a group of about 16,000 man-made compounds that are most commonly used to make products that are resistant to water, stains, and heat. PFAS are known as “forever chemicals” because they do not break down naturally and are known to accumulate in the human body. PFAS have been linked to cancer, birth defects, liver disease, thyroid disease, a dramatic drop in sperm count, and a variety of other serious health problems.

As the transition unfolds, public health advocates have begun sounding the alarm about the need to find alternatives to toxic chemicals used in clean energy technologies like batteries and wind turbines.

The paper notes that few end-of-life standards exist for PFAS battery waste, and most ends up in municipal waste sites, where it can leach into waterways, accumulate locally or be transported long distances.

When historical leachate samples were examined for the presence of the chemical, no detections were found in samples taken before the mid-1990s, when the chemical was commercialized.

The study points out that while BisFASI can be reused, previous research has shown that only 5% of lithium batteries are recycled. Unless battery recycling is dramatically scaled up to keep up with demand, it is predicted that 8 million tonnes of battery waste will be generated by 2040.

“This shows we need to look more closely at this class of PFAS,” Guelfo said.

Little toxicity data exists on bis-FASI, so the study also looked at its effects on invertebrates and zebrafish. Effects were seen even at low levels of exposure, suggesting it may be as toxic as other PFAS compounds known to be dangerous.

Skip Newsletter Promotions

Researchers also took water, soil and air samples around a 3M plant in Minnesota and other large facilities known to make the chemical. Guelfo said the levels in the soil and water are of concern, and that detection of the chemical in the snow suggests it could easily travel through the air.

This could help explain why the chemicals have been found in China’s seawater and other remote locations not close to production plants.

The most commonly used definition of PFAS worldwide includes bis-FASIs, but one division of the EPA considers them to not belong to a chemical class, and therefore they are not included in the list of compounds monitored in U.S. waters. The EPA’s narrow definition of PFAS has been criticized by public health advocacy groups for excluding some chemicals at the urging of industry.

But the new study, combined with previous evidence, shows that bisFASI, like most other PFAS, is persistent, mobile and toxic, said co-author Lee Ferguson, a researcher at Duke University.

“This classification, coupled with the massive increase in clean energy storage that we’re seeing, should at the very least sound alarm bells,” he said.

Snowball Earth’s harsh environmental conditions provided a competitive edge for the evolution of multicellular organisms

Fossil and molecular evidence suggests that complex multicellular organisms arose and proliferated during the Neoproterozoic Era (1-541 million years ago). An extreme glacial period during the Cryogenian Period (720-635 million years ago), an event commonly referred to as Snowball Earth, led to dramatic changes in Earth's climate and oceans. New research suggests that Snowball Earth was an environmental trigger for the proliferation of complex multicellularity across multiple groups of eukaryotic organisms.

Solving the mystery of why multicellular organisms emerged could help pinpoint life on other planets and explain the enormous diversity and complexity seen on Earth today, from marine sponges to redwoods to human societies.

The prevailing thinking is that oxygen levels must reach a certain threshold for a single cell to form a multicellular colony.

However, the oxygen story does not fully explain why the multicellular ancestors of animals, plants and fungi emerged simultaneously, or why the transition to multicellularity took more than a billion years.

The new study shows how the specific physical conditions of Snowball Earth, particularly the viscosity of the oceans and the depletion of resources, may have led eukaryotes to become multicellular.

“It seems almost counterintuitive that these extremely harsh conditions – this frozen planet – could actually select for larger, more complex organisms, rather than causing species to become extinct or shrink in size,” said William Crockett, a doctoral student at MIT.

Using scaling theory, Crockett and his colleagues found that a hypothetical ancestor of early animals, reminiscent of swimming algae that fed on prey instead of photosynthesizing, would have grown in size and complexity under Snowball Earth pressures.

In contrast, single-celled organisms that move and feed by diffusion, such as bacteria, will grow small.

“The world changed after Snowball Earth because new life forms emerged on the planet,” said Professor Christopher Kemps of the Santa Fe Institute.

“One of the central questions of evolution is: How did we evolve from nothing on Earth to beings and societies like us? Was it all by chance?”

“We don't think it's luck. There are ways to predict these big changes.”

The study shows how, during the Snowball Earth era, the oceans froze, blocking sunlight and reducing photosynthesis, which resulted in nutrient depletion in the oceans.

Larger organisms that could process more water were more likely to eat enough to survive.

As the glaciers melt, these large creatures could expand even further.

“Our study provides hypotheses about ancestral features to look for in the fossil record,” Crockett said.

International Monetary Fund (IMF) calls for consideration of balancing the effects of AI with profit and environmental taxes

The International Monetary Fund (IMF) suggests that governments dealing with economic challenges brought about by artificial intelligence (AI) should look into implementing fiscal policies such as taxes on excessive profits or environmental taxes to offset the carbon emissions linked to AI.

The IMF highlights generative AI, which enables computer systems like ChatGPT to create human-like text, voice, and images from basic prompts, as a technology advancing rapidly and spreading at a swift pace compared to past innovations like the steam engine.

To address the impact on jobs due to AI, the IMF proposes policies like a carbon tax considering the environmental effects of operating AI servers. The IMF emphasizes the importance of taxing carbon emissions from AI servers to incorporate environmental costs into the technology’s price.


The IMF report released on Monday highlights the significance of taxing carbon emissions associated with AI servers due to their high energy consumption and the potential to impact data centers’ electricity use. Data centers, servers, and networks currently contribute up to 1.5% of global emissions, according to a recent report.

In addition, the report cautions that introducing AI could reduce wages, widen inequality, and empower tech giants to strengthen their market dominance and financial gains. It recommends higher taxes on capital income, including corporate taxes and personal income on dividends, interest, and capital gains, to address these challenges.

Furthermore, the report stresses the need for governments to prepare for the impact of AI on various job sectors, both white-collar and blue-collar, and suggests measures like extending unemployment insurance, targeted Social Security payments, and tailored education and training to equip workers with necessary skills.

To overhaul the tax system and introduce new taxes reflecting real-time market values, the IMF recommends leveraging AI’s analytical capabilities. While cautioning against universal basic income due to its high cost, the IMF suggests considering it if AI disrupts jobs significantly in the future.

Ella Dabra Norris, deputy director of the IMF’s Fiscal Affairs Department and co-author of the report, encourages countries to explore the design and implementation of systems like UBI if AI disruption intensifies.

The US government has proposed taxing crypto miners to reduce the industry's heavy environmental impact, but experts say the measure could simply shift the problem elsewhere. It warns that there is.

Cryptocurrencies such as Bitcoin are kept secure through a process called mining, which involves intensive calculations and large amounts of power consumption. According to the latest data from the University of Cambridge, Bitcoin is 0.69% of all electricity used worldwide.

In America, the government Estimate Up to 2.3 percent of the nation's electricity use in 2023 will come from just 137 mining operations, and electricity rates in Texas are increasing by 5 percent. Directly linked to increased demand Caused by miners.President Joe Biden's 2025 budget proposal Cryptocurrency mining “has the potential to harm the environment, increase energy prices for those who share power grids with digital asset miners, as well as have environmental justice implications.”

The budget therefore proposes a 30% tax on miners' total energy costs, which would apply to both electricity from the grid and electricity generated by miners themselves. It will be phased in, with 10 percent starting in 2025, 20 percent in 2026, and finally 30 percent in 2027. A similar tax was proposed by Biden last year but did not pass. Although passed by the House and Senate and signed into law, this second attempt now faces hurdles.

The move, which comes as Bitcoin has soared to an all-time high of more than £56,000 in recent weeks, has drawn heavy criticism from the crypto industry.Dennis Porter of Satoshi Action Fund tweeted It claimed this was a “backdoor ban” on mining and promised: “We will vigorously oppose this attempt at targeted discrimination without hesitation!”

new scientist Several large Bitcoin mining companies have been approached for comment on the proposed tax. Block Mining, Frontier Mining, and HIVE Digital Technologies did not respond, while TeraWulf declined to comment.

But taxing the industry could have unintended consequences. alex de vries At VU Amsterdam in the Netherlands. China's ban on bitcoin mining in 2021 has prompted companies to move operations to countries such as Kazakhstan, where more than 90% of the country's electricity supply comes from fossil fuels such as coal.

“Perhaps it doesn’t actually solve anything, because mining operations are highly mobile and can be based anywhere, moving from country to country in search of better regulatory environments or cheaper power.” They won’t, says De Vries. “Climate change is a global problem, and moving emissions from one country to another, or worsening power supplies, is actually making the global problem worse.”

“Ideally, we would like to address this issue at a global level,” says de Vries. “You want to reduce the emissions of these miners.” De Vries has long advocated for Bitcoin to follow the lead of the cryptocurrency Ethereum, which has changed the way it operates. changed, abolished mining, and reduced power consumption by 99.99%. But most Bitcoin developers weren’t interested in the change, he said.

Eco-friendly dyeing method for denim could lessen the environmental impact of jeans

Harmful chemicals are used to dye jeans blue

A new technique that dyes denim using chemicals that turn blue in sunlight could reduce the environmental impact of jeans production.

Blue denim is dyed with indigo. Indigo is a compound that was once extracted from plants, but is now usually synthesized. Harmful chemicals such as sodium dithionite are required to dissolve indigo in water so that it can be used for dyeing. These chemicals produce toxic fumes that can harm the health of textile workers and can also cause toxic pollution of wastewater.

now, Ditte Hededam Werner Researchers at the Technical University of Denmark have instead developed a new process that uses a natural precursor of indigo called indican.

“Indican is also a natural product, so it's not artificial or weird,” says Hededam-Werner. “But the good thing about this is that it's soluble, so you can basically just soak the fabric, which you can't do with indigo. So many harsh chemicals simply This made it a very attractive solution to this problem because it could be omitted.”

However, there is one important drawback. Indican is colorless, so the compound must be converted to indigo after being applied to the material. One way to do this is to leave it in the sun for a few hours.

“I don't know if consumers like it or not, but if you wear Indian-soaked jeans in the sun, they turn blue over time,” says Hededam-Werner. “You think it's a gimmick, don't you? You can do it.”

The research team has discovered two methods that can provide the faster, more reproducible results required by modern manufacturing. One method uses plant enzymes and the other uses electric light.

Using light is a simpler process that reduces the environmental impact of dyeing by 73% compared to using indigo. European Commission indicators It takes into account carbon emissions, land use, water consumption, and ozone layer depletion. Using enzymes led to even greater reductions of 92%.

Hededam-Werner said that with further research, the process could become cheaper and more efficient, but major obstacles still stand in the way, not least of which is the production of the 4 billion pairs needed. The aim is to establish a supply chain for 80,000 tons of Indican. Number of jeans manufactured each year.

Interview with Hannah Ritchie: “Environmental Anxiety Isn’t Very Productive”

With constant headlines about floods, bushfires, and record temperatures, it’s surprising how many people think our current generation will be in even worse trouble than when we inherited the planet. Not. But is that belief true? hannah richie I do not think so. She is cautiously optimistic that we may be the first generation to inherit the environment in better shape than it was back then.

She came to this counterintuitive conclusion after a decade of digging into the environmental record as a data scientist at the University of Oxford and principal researcher at the influential online publication Our World in Data.in her new book it’s not the end of the world, Ritchie lays out graphs that show the positive steps we’ve already taken to change our behavior and mitigate climate change, from reducing coal usage to reducing carbon emissions. I am.she speaks new scientist She talks about her growing confidence that we can solve the world’s environmental problems and lists some key trends that give us hope that we can turn things around.

Alison George: I’m talking about that day. report We’ve seen a dramatic increase in online searches related to “environmental anxiety.” Still, you study long-term environmental trends and are reasonably optimistic.

Hannah Ritchie: There’s still some anxiety and worry, but I think there’s now a sense of optimism that things can change. That fear is completely valid, and I can understand why people feel that way. I feel it. However, that feeling alone is not very helpful. You need to combine your senses…

The Power of Salt and “Baking” in Addressing Environmental Challenges

Chemists at the University of Copenhagen have made a significant breakthrough in textile recycling by developing an environmentally friendly method to recycle polyester using Harthorn salt. Polyester, which is the second most used fiber in the world, poses a threat to the environment as very little of it is currently recycled. The fabric is a combination of plastic and cotton, making it challenging for the industry to separate and recycle. However, the chemists have discovered a simple solution using a single ingredient found in households.

Polyester is found in various everyday items, such as clothing, sofas, and curtains, with an astonishing 60 million tonnes of the fabric being produced annually. Unfortunately, the production and lack of recycling have a negative impact on the climate and environment, as only 15% of polyester is recycled, while the rest ends up in landfills or incineration, contributing to carbon emissions.

Recycling polyester presents significant challenges, particularly in separating the plastic and cotton fibers without losing them. Traditional methods prioritize preserving the plastic components, resulting in the loss of cotton fibers. These methods are also expensive and complex, with the use of metal catalysts generating harmful waste.

In a revolutionary development, a team of young chemists has found a remarkably simple solution to this problem that could transform sustainability in the textile industry. The researchers have developed a traceless catalytic methodology that allows for the depolymerization of polyester into monomers in an easy and environmentally friendly approach, at a large scale.

The process requires no special equipment and only relies on heat, a non-toxic solvent, and common household materials. By cutting a polyester garment into small pieces and placing them in a container with a mild solvent and Harthorn salt (ammonium bicarbonate), the mixture is heated to 160 degrees Celsius and left for 24 hours. The result is a liquid where the plastic and cotton fibers separate into distinct layers. This simple and cost-effective process preserves the cotton fiber while breaking down the polyester.

The Harthorn salt is broken down into ammonia, CO2, and water during the process. The combination of ammonia and CO2 acts as a catalyst, selectively breaking down the polyester while keeping the cotton fibers intact. The use of ammonia in combination with CO2 is environmentally friendly and safe. Due to the mild nature of the chemical reaction, the cotton fibers remain in excellent condition.

The researchers were pleasantly surprised by the success of their simple recipe for recycling polyester. Although the method has only been tested in the laboratory, the researchers believe it is scalable and are currently exploring partnerships with companies to test the method on an industrial scale. They are determined to commercialize this technology, which has the potential to make a significant impact on textile recycling.
