Assessment of UNESCO Sites Reveals Climate Impacts (Mongabay)  

Initial data from the first ever global biodiversity and climate assessment indicates that 98% of UNESCO’s 2,200+ World Heritage Sites, Biosphere Reserves, and Geoparks have experienced at least one climate-related extreme event since 2000, including massive wildfires, droughts, and retreating glaciers. The effort to track such effects will now be augmented by UNESCO’s new Sites Navigator, a geospatial platform that integrates over 40 datasets to track climate impacts, biodiversity loss, and socioeconomic conditions in real time.

“Intractable” systemic problems mean carbon offsets fail to cut global heating  (The Guardian) 

A recent review of 25 years of evidence found that carbon credit quality issues stem from deep-seated structural flaws, and not isolated cases of fraud. Researchers point to four major flaws that undermine most carbon offset projects. The worst problems include issuing credits for already-planned projects, impermanent solutions (forests that later burn), incidences of leakage (such as protecting one forest area while pushing logging elsewhere), and double-counting which allows both seller and buyer to claim the same emission reduction.  

Launched in 2013, China’s Belt and Road Initiative (BRI) has drawn wide global attention, with scholars and policymakers examining its geopolitical and economic implications. Much less explored, however, are the subnational impacts of BRI in participating countries. The China Pakistan Economic Corridor (CPEC), adopted as Pakistan’s flagship BRI project in 2015, offers a case in point.

Nickel Mining Threat to New Raja Ampat UNESCO Biosphere Reserve (Mongabay) 

When Indonesia’s Raja Ampat archipelago received a UNESCO Biosphere Reserve designation on September 27, 2025, the new designation adding to the status it won as a Global Geopark in 2023. Yet this dual honor highlighting the archipelago’s exceptional biodiversity is now under threat from intense pressure from global demand for nickel for electric vehicle batteries that is challenging the reserve’s conservation goals.  

Environmental crime has long been underreported, but globalization and the increased involvement of organized crime involvement is now contributing to a rise in such crime, especially when compared to other types of crime. The financial toll of environmental crimes has been estimated to be hundreds of billions of dollars while the damage they cause to ecosystems compounds the effects of climate change and inflicts a heavy toll on vulnerable communities.

High Seas Treaty Passes UN Ratification Threshold for Implementation (New York Times) 

Last week, the High Seas Treaty reached 60 ratifications in the United Nations, crossing the threshold to take effect and triggering a four-month countdown to full implementation.

Mexico’s Mercury Boom is Poisoning People and the Environment (Associated Press)

In Mexico’s Sierra Gorda mountains, soaring international gold prices also have created a mercury boom. Since 2011, mercury prices have skyrocketed from $20 per kilogram to between $240 and $350 per kilogram today. Most of Mexico’s mercury is trafficked to Colombia, Bolivia, and Peru for use in illegal Amazon gold mining operations that contaminate rivers and ecosystems. Yet the country’s adoption of a 2017 UN convention banning mercury mining and exports also allows artisanal mines to operate until 2032.

While the devastating cyclones Dineo (2017) and Idai (2019) may feel like distant memories on the global stage, their impact remains etched into daily life in Zimbabwe’s Tsholotsho and Chimanimani districts. A punishing regional drought in 2024 makes the picture here even clearer: food, land, and water systems have been reshaped in ways that directly influence social cohesion and stability.
