NASA satellite detects high carbon monoxide across Southeast Asia as Indonesia fires burn

NASA satellite observations show elevated carbon monoxide concentrations across Southeast Asia, linked to fires in Indonesia. Carbon monoxide is produced by incomplete combustion, so it works as a smoke tracer even when clouds hide the fire from optical sensors. The pattern is a reminder that fire season in Indonesia carries regional consequences, not just local ones. High CO readings matter for air quality because the same plume often carries fine particulate matter and other pollutants. For people in Singapore and nearby countries, that can mean haze episodes and health advisories. It also raises the question of how much carbon these fires release, especially when they burn into peatlands, which store large amounts of carbon and can smolder for weeks. Satellite monitoring gives early warning, but it does not stop land clearing. The long-term fix depends on enforcement, land-use planning, and making peatland protection economically viable for local farmers and companies.
