Overview

• A recent study highlights increasing frequency and intensity of ocean upwellings due to climate change, leading to mass die-offs of marine life.
• Extreme cold events, driven by shifts in ocean currents and atmospheric pressures, are causing sudden drops in sea temperatures.
• Marine species such as bull sharks and manta rays are particularly vulnerable to these cold snaps, which can lead to large-scale mortalities.
• Researchers emphasize the need for enhanced marine conservation efforts to protect species from these increasingly common cold events.
• The study, published in Nature Climate Change, calls for urgent action to address the complexities of climate change impacts on marine ecosystems.
