Polynyas are large openings in polar sea ice that can influence global climate and ocean circulation. After disappearing for 40 years, major polynyas reappeared in the Weddell Sea in 2016 and 2017, sparking new scientific questions. Our review explores how ocean currents, atmospheric conditions, and deep ocean heat drive their formation. These polynyas impact ecosystems, carbon exchange, and deep water formation, but their future remains uncertain, requiring better observations and models.
