As reflective ice melts, the ocean surface may absorb more solar energy, raising ocean temperatures and starting a feedback loop the melts the remaining ice faster. (livescience.com)
When bright, white, reflective ice melts to reveal darker ocean water, sunlight that would normally bounce back into space is absorbed instead. (climatecentral.org)
This change — reducing the amount of white, reflective ice surface — led to further warmth, in a feedback effect. (grist.org)
