Arctic Heatwaves Spike as Sea-Ice Loss Doubles Sun Absorption

Summary

Story summary

Russia reports anomalous atmospheric heating after sea-ice retreat triggers Arctic heatwaves.
Southerly winds push ice edges, bring warm air, sparking Barents and Bering heatwaves.
Early summer melt halves albedo, doubling solar absorption in 2007 and 2020, extending events ~20 %.
Models show downward ocean heat fluxes provide over two-fifths of dissipation and one-fifth of onsets.
Scientists propose a cloud–longwave feedback where more summer clouds may raise heatwave frequency.
