As COP30 Concludes, Experts Call for Reform (Reuters)
Interviews with experts attending COP30 highlight a growing movement for reform to the UN climate negotiations. In particular, there is alignment on a key critique of the current COP structure which calls for a full consensus of nearly 200 countries to make decisions. Since this requirement historically has allowed more ambitious efforts to be blocked during negotiations, suggestions for reform have included the following: a shift to a majority-vote model, holding COP every other year, convening smaller action-focused gatherings, and downsizing COP to exclude big business contingents.

Rising Food Insecurity is Driving Instability (Foreign Affairs)
Since 2020, the number of people facing acute hunger and chronic food insecurity has increased 130% above existing levels. And supply is not the issue. At present, the world produces enough food to feed nearly 10 billion people, yet there are 720 million people who are food insecure and a further 319 million face acute hunger. Today’s hunger is driven instead by barriers to access.

Closing the Climate Finance Gap in Fragile States
›November 11, 2025 // By Madelyn MacMurrayA massive flood in Somalia killed hundreds of people, and displaced tens of thousands more. Yet the survivors faced a vexing prospect when they tried to return home: Al-Shabab had moved in.
Stephanie Speck, Head of Special Initiatives at the Green Climate Fund, observed at a recent Stimson Center event that Shabab’s new levies meant that residents could not to move back to farm their land.

Corruption Stymies Environmental Crime Fight in the Amazon (Mongabay)
In the Andean Republics, rampant systemic judicial corruption has challenged the entire justice system, with judges implicated in both bribery and extortion. Because leadership from judges is essential for the success of reform efforts ranging from anti-corruption campaigns to environmental crime enforcement, the result has been damaging to the entire justice system in the region for more than a decade.

Revisions to Indonesian Law Promote Unregulated Mining (The Diplomat)
Since gold was discovered in 2011 on Mount Botak in Indonesia, thousands of miners have flocked to the area without official permits. It is an influx which has transformed this northeastern region from an agricultural center into a hub of small-scale, unregulated mining. Uncontrolled use of mercury and cyanide has severely polluted local rivers, with mercury levels in the Waekase River reaching 0.05 mg/L—or 50 times the WHO’s safety threshold. Yet despite the government’s move to close the mine in 2015, illegal activity continues. Ineffective law enforcement has caused ecosystem destruction, public health threats (including neurological disorders and kidney damage) and deadly conflicts between residents.

›US Resistance Delays Vote on Shipping Decarbonization Rules (Mongabay)
The International Maritime Organization (IMO) has voted 57-49 to postpone the adoption of the “net-zero framework” until October 2026. As the shipping sector’s first binding deal on global greenhouse gas emissions, the agreement would have established progressively stricter intensity limits starting in 2028. The framework also imposed substantial fees for noncompliance, with high emitters facing up to $1.5 million in additional annual fees by 2035 that could raise fuel costs by roughly 20%. Low-emission vessels would be rewarded with tradable carbon allowances.

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.
