Chapman University researchers, in collaboration with the U.S. Forest Service and others, published a study in Nature Communications showing that warming tropical rainforest soils release vast amounts of carbon dioxide, potentially accelerating climate change. In Puerto Rico, experimentally heated plots showed a 42–204% increase in soil respiration, among the highest CO₂ release rates ever recorded. The findings suggest that instead of acting as carbon sinks, tropical soils could become major carbon sources, intensifying global warming. Chapman’s Dr. Christine Sierra O’Connell co-led the research as part of the TRACE project.

Vertical farming offers a much-needed opportunity to secure food production in the face of climate change, but can it truly deliver a sustainable alternative to field-grown crops? A new study led by the University of Surrey has found that while vertical farms dramatically increase lettuce yields and use far less water, the carbon footprint still exceeds traditional lettuce farming – raising important questions about how the UK can balance food security with environmental responsibility. 

Modern ‘sustainable’ innovations in architecture are failing to slow climate change,  but revisiting ancient knowledge and techniques found in traditional architecture could offer better solutions.
