Gulf of Panama's 'Sea's Breath' Halts After 40 Years: Global Concern

• The seasonal 'upwelling' in the Gulf of Panama completely failed in 2025 for the first time in 40 years, depriving marine ecosystems of essential coldness and nutrients.
• This anomaly led to unusually warm waters instead of the typical cooling, breaking a four-decade-old temperature record and creating a food crisis for fish and stress for coral reefs.
• Upwelling, known as the 'sea's breath', is a process where strong winds push surface water away, allowing nutrient-rich cold water from below to rise, feeding phytoplankton and cooling coastal waters.
• The 2025 failure was due to a 74% reduction in the frequency of northerly winds, preventing continuous upwelling despite some strong gusts.
• This event poses a significant threat to coral reefs, increasing their vulnerability to thermal stress and potentially leading to widespread bleaching, directly impacting the livelihoods of coastal communities and global food supply.
