Greenland and Antarctica have lost over 12 trillion tons of ice in 47 years, according to a study. The loss is attributed to warmer waters, not just hotter air, with five-sixths of the melt linked to ocean temperatures. The findings are part of a broader scientific consensus on accelerating ice sheet melting.

Commenters are split. Some, like xiao, argue that satellite data confirms the ice loss and emphasize the urgency of the findings. Others, like floofloof, stress the implications for sea level rise and coastal vulnerability. A few users question the reliability of the study’s methodology, suggesting the data may be overstated or misinterpreted.

The community largely agrees that the ice loss is real and significant, with major consequences for global sea levels. However, debates over the study’s credibility and the role of warmer waters versus air temperatures highlight ongoing scientific and public skepticism.
