Stardust Solutions Develops Solar Geoengineering Particles, Raising Scientific Concerns

Stardust Solutions Develops Solar Geoengineering Particles, Raising Scientific Concerns

Stardust Solutions, an Israeli-US company founded in 2023 by former Israeli government nuclear physicists, is advancing solar geoengineering technology. Their plan involves creating tiny particles from common substances like a food additive (amorphous silica) and the mineral found in eggshells (calcium carbonate), then spraying them into the atmosphere to reflect sunlight and cool the Earth. The company has developed two types of particles: one made entirely of amorphous silica and another with a calcium carbonate core surrounded by amorphous silica. Stardust Solutions claims that deploying one million tons of these particles annually could achieve 0.9 degrees Fahrenheit of cooling at a cost of approximately $10 billion per year. This approach mimics natural phenomena, such as volcanic eruptions that temporarily lower global temperatures by releasing sulfur dioxide into the atmosphere. The company emphasizes that this technology is not a complete solution to climate change but rather a tool to buy time for...

Ireland Faces Significant Failure in Meeting Tree Planting Targets, Climate Watchdog Warns

Ireland Faces Significant Failure in Meeting Tree Planting Targets, Climate Watchdog Warns

A climate watchdog has issued a warning that Ireland is set to 'grossly fail' in achieving its annual target of planting 22 million trees, which translates to 8,000 hectares. A climate action plan established by the government in 2019 aimed for an 18% increase in forest cover by mid-century. However, the government missed its 2025 target by a substantial 68%, planting only 2,527 hectares, or approximately 6.9 million trees. The situation has worsened, with only 1,573 hectares planted in 2024, following 1,652 hectares in 2023 and 2,273 hectares in 2022. As of June this year, only 777 hectares (about 2.1 million trees) have been planted, a significant decrease compared to 1,513 hectares (about 4.2 million trees) by the same time last year. The Climate Change Advisory Council's latest annual review indicates that the commitment to 18% tree cover is becoming 'increasingly unrealistic' and highlights the forestry sector as a 'particular concern'. The council also noted that the agricultural sector failed to mee...

UNEP Warns World Likely to Breach 1.5°C Global Warming Threshold Soon

UNEP Warns World Likely to Breach 1.5°C Global Warming Threshold Soon

The UN Environment Programme (UNEP) has issued a warning that the world is projected to exceed the 1.5°C global warming threshold within the next few years. This projection indicates a temporary breach, meaning temperatures will likely rise above this critical limit before potentially declining as greenhouse gas emissions are reduced. The UNEP report outlines a pathway described as 'overshoot, peak, and decline,' where global temperatures temporarily surpass 1.5°C. This scenario emphasizes the urgent need for immediate and coordinated global actions to mitigate further warming. The report suggests that implementing clean air and climate change initiatives could significantly reduce carbon dioxide emissions by 2050, cut methane emissions by 60%, and decrease major air pollutants by approximately 70%. Such measures could prevent about 0.34°C of global warming by 2050 and a more substantial 1.4°C by 2100.

Swiss Scientists Test Sheep's Wool as Biodegradable Glacier Cover Alternative

Swiss Scientists Test Sheep's Wool as Biodegradable Glacier Cover Alternative

Scientists in Switzerland have successfully tested sheep's wool as a biodegradable alternative to synthetic plastic covers for protecting glaciers from melting. The 'Keep It Wool' trial on the Tsanfleuron Glacier involved covering 200 square meters of high-altitude Alpine ice with prototype wool blankets. Measurements taken every two weeks throughout the summer demonstrated that the wool blankets reduced ice loss by approximately the same amount as conventional synthetic covers, which typically cut local melting by 50 to 70 percent. This joint project, initiated by four master's students and developed with the Summit Foundation, the University of Lausanne, and the Swiss Glacier Monitoring Network (Glamos), aims to find a natural, sustainable solution to glacier protection. The wool panels were manufactured by Swiss textile company Fisolan, and early results indicate the natural fiber's surprising stability against harsh weather conditions.

Global Coalition Proposed to Implement Carbon Pricing in Key Industrial Sectors

Global Coalition Proposed to Implement Carbon Pricing in Key Industrial Sectors

A recent study published in the Science journal suggests that a global coalition of countries could significantly reduce greenhouse gas emissions and generate substantial public revenue by adopting carbon pricing across four major industrial sectors: iron, steel, aluminum, cement, and fertilizers. These industries collectively account for approximately 20% of global greenhouse gas emissions. The proposed coalition would involve member countries introducing carbon pricing for these industries domestically and applying carbon charges to imports from non-member countries. This approach aims to address 'carbon leakage,' where companies relocate production to countries with less stringent climate policies, and the 'free-rider' problem, where some countries benefit from global emission reductions without contributing equally. The study, titled 'Building a scalable climate coalition for heavy industry,' highlights that such a system could also incorporate varying carbon prices based on countries' income levels, a...

Study Links Climate Change to Record Warm Winter in Western U.S.

Study Links Climate Change to Record Warm Winter in Western U.S.

A study published in the journal PNAS has found that the record-breaking warm winter of 2025-2026 in the Western United States was approximately four times more likely due to human-caused climate change. Researchers, including scientists from the University of Wyoming, used advanced climate models to analyze snow water equivalent (SWE) data and atmospheric conditions. The study revealed that the winter season was not only unusually warm but also marked by significantly low snowfall, particularly in the Upper Colorado River Basin. The findings suggest that such snow droughts are becoming more frequent due to climate change.

UN Environment Programme Report Highlights Significant Economic and Health Returns from Climate and Clean Air Action

UN Environment Programme Report Highlights Significant Economic and Health Returns from Climate and Clean Air Action

A report by the UN Environment Programme (UNEP) and the Climate and Clean Air Coalition (CCAC) indicates that every US$1 invested in combined climate change and air pollution action can yield approximately US$15 in economic benefits. This assessment, titled 'Hidden assets: The economic and health case for climate and clean air action,' evaluates 25 proven solutions across various sectors including energy, industry, transport, agriculture, cooking, and waste. The findings suggest that integrated action provides greater returns than addressing these issues separately, with an internal rate of return of 60 percent and market returns surpassing costs within a decade. The report emphasizes that by 2050, these solutions could prevent 144 million premature deaths and hundreds of millions of chronic disease cases. It also identifies institutional barriers, rather than technical or economic ones, as the primary impediments to implementation, noting that investments in enabling conditions could accelerate full imple...

African Union Initiative Succeeds in Regrowing 200 Million Trees in Niger Through Farmer-Managed Natural Regeneration

African Union Initiative Succeeds in Regrowing 200 Million Trees in Niger Through Farmer-Managed Natural Regeneration

The African Union's Great Green Wall initiative, initially conceived as an 8,000-kilometer band of planted trees across Africa to combat desertification, faced significant challenges with high seedling mortality. However, a new approach, Farmer Managed Natural Regeneration (FMNR), has led to the successful regrowth of approximately 200 million trees in Niger. This method, pioneered by Australian agronomist Tony Rinaudo in the 1980s, involves protecting and pruning existing tree stumps and root systems that are already present underground, rather than planting new seedlings. Farmers select the strongest shoots from these existing systems, shield them from livestock, and prune other growth to direct energy into the chosen stems. This technique eliminates the need for nurseries, trucking, and watering, leveraging the resilience of established root systems. The success of FMNR was also significantly boosted by changes to colonial-era laws that previously disincentivized farmers from protecting trees on their l...

Air Conditioning Use Escalates Global Warming Despite Saving Lives in the U.S.

Air Conditioning Use Escalates Global Warming Despite Saving Lives in the U.S.

Air conditioning (AC) is saving over 5,000 lives annually in the U.S. by mitigating the effects of extreme heat, according to a study in Nature Health. However, this life-saving technology is simultaneously contributing to global warming and straining electrical grids. As global temperatures rise and heat waves become more frequent across continents, the demand for AC is skyrocketing. The International Energy Agency and the UN Environment Programme project that electricity demand for cooling will triple. Yale epidemiology professor Kai Chen, a senior author of the study, notes that while AC is essential for saving lives, its reliance on fossil fuels for electricity generation leads to increased carbon emissions. The UN estimates that heat-trapping gas emissions from AC use are expected to rise from 4.5 billion tons to 7.2 billion tons in the next 25 years, a figure nearly equivalent to the current carbon pollution from the U.S. and Europe combined.
