The Cryosphere Pavilion traditionally has five displays, one for each of the main cryosphere dynamics: ice sheets, mountain glaciers and snow, permafrost, polar oceans, and sea ice. During COP27, the fifth totem was almost toppled over on its side, with the remaining four standing tall. Based on the conclusions of the IPCC Sixth Assessment and in close consultation with sea ice scientists, displaying this nearly-fallen totem symbolized the first \u201clost\u201d cryosphere threshold. The IPCC noted that even with very low emissions, summer loss of Arctic sea ice \u2013 defined as sea ice extent falling below one million km2 \u2013 will occur at least once, likely before 2050. Although the loss of summer Arctic sea ice can no longer be prevented, emission reductions consistent with the 1.5\u00b0C Paris limit are the only means available to decrease the risk of passing remaining cryosphere thresholds as well.<\/p>\n
