At a private meeting during the UN general assembly in New York on Wednesday night, Ed Miliband presented findings from a report produced by the UK's spy chiefs. The report concluded that the collapse of natural systems worldwide would lead to conflict, migration and food shortages.
According to the Guardian, the document was previously suppressed under Keir Starmer's leadership. Miliband's presentation to EU foreign ministers, alongside representatives from Kenya and other countries, marks the first time the findings have been shared internationally.
The warning highlights El Niño as an immediate threat, with climate and nature crises framed as direct challenges to national security and defence planning.
