Since the adoption of the 2015 Paris Agreement, global climate governance has shifted from binding international targets to a framework based on voluntary commitments by states, cities, businesses, and even individuals. At first glance, this pluralistic approach may seem like progress—more actors should, theoretically, lead to more action. However, Florian Steig and Angela Oels (2025) argue that this shift has, in fact, entrenched a system of what they term “organized irresponsibility,” where the semblance of action masks the persistence of deeper (...) structural problems.

Khi cháy rừng gia tăng trên khắp Bắc Mỹ, chúng không chỉ để lại vùng đất cháy đen, mà còn những đám mây bụi mịn vô hình—đặcbiệt là PM₂.₅ (các hạt bụi có đường kính nhỏ hơn hoặc bằng 2,5 micron)—.

As wildfires intensify across North America, they leave more than scorched earth in their wake. Invisible clouds of fine particulate matter—PM₂.₅, measuring 2.5 microns or smaller—travel vast distances, infiltrating lungs and triggering serious health consequences [2-4]. A recent study by Bashan, Li, and Wang [5] introduces a novel method to track these pollutants using dynamic spatial networks that capture the systemic spread of air pollution across the United States.

The Northern Mealy Amazon (Amazona guatemalae), a large and striking parrot native to Central America, is increasingly threatened by human activities. A recent study by De Labra-Hernández and Renton (2025) investigated the key factors influencing nest success in this species within the biodiverse yet unprotected forests of Los Chimalapas, Mexico.
