US policy, gangs and climate change are reshaping Central America

Migration and democratic decline in Central America cannot be understood separately from the intertwined impacts of US intervention, gang violence, economic instability and climate disruption. As droughts, displacement and insecurity deepen, the region faces growing pressure toward both migration and authoritarian rule.

Wars destroy lives and the climate. Why aren’t we counting military emissions?

War is a major driver of greenhouse gas emissions, yet most conflict-related emissions remain excluded from official climate accounting. Governments and international climate bodies must begin treating military emissions and the climate costs of war as central issues of accountability and justice.

Understanding how plants pause and restart growth can help develop climate‑resilient crops

New research shows that plants can temporarily halt root growth under stresses like cold and drought, then rapidly restart it once conditions improve. By identifying the genes behind this “pause and push” response, scientists hope to develop crops that recover more quickly from extreme weather, strengthening food security in a changing climate.
