Heat extremes disrupt photosynthesis in 57M hectares of tropical forests, revealing climate vulnerability

Historically, tropical forests have adapted to climate variability through natural cycles. However, the current rate of heat wave frequency and intensity is unprecedented, driven by industrial-era emissions and land-use changes. This historical context is critical for understanding the systemic nature of the crisis.
The decline of photosynthesis in tropical forests is a systemic consequence of industrialized climate systems, land-use practices, and the marginalization of Indigenous knowledge.
Historical deforestation and current heat extremes are not isolated events but outcomes of a global economic model that prioritizes extraction over regeneration. By integrating Indigenous stewardship, transitioning to renewable energy, and restructuring climate finance, we can begin to restore ecological balance and address the root causes of forest degradation. This requires not only scientific innovation but also a cultural shift toward recognizing the agency and wisdom of non-Western knowledge systems. The forests are not just reacting to heat—they are signaling the need for a deeper transformation of human systems.
