NASA’s SCISAT satellite, vital for monitoring ozone layer recovery, faces imminent retirement without a replacement. Scientists warn that losing this tool could hinder global efforts to track ozone-depleting substances and assess climate treaties’ effectiveness. The ozone layer, crucial for blocking UV radiation, has shown recovery since the Montreal Protocol. However, unresolved threats like illegal CFC emissions and climate change necessitate continuous monitoring. Experts urge governments to fund next-generation satellites to prevent a data gap threatening environmental and public health.
