Whale songs function like acoustic billboards in the ocean. When city streets go quiet, people notice. When quieter oceans replace vibrant whale songs, scientists treat it as a warning sign.
Marine heatwaves create incredibly stressful conditions. The National Oceanic and Atmospheric Administration (NOAA), part of the U.S. Department of Commerce, tracks these events as part of monitoring ocean health. According to the NOAA and the World Meteorological Organization, extreme events in the ocean are becoming more common as climate change intensifies.
Commercial whaling once drove blue and fin whales to low numbers worldwide. Today, most widespread poisoning from pollutants, noise pollution from ships, and rapid shifts in the marine environment add new pressure.
Each stressor alone matters. Together, they raise concerns about cumulative pressure on marine ecosystems in vulnerable regions
