Harmful tipping points in the natural world threaten humanity by disrupting life support systems and societal stability.

The Antarctic Ice Sheet exhibits hysteresis and irreversible ice loss, with West Antarctic collapse contributing over 4 m of sea-level rise even under minimal additional warming, according to 800,000-year transient and equilibrium simulations using the Parallel Ice Sheet Model.

Strong governance, accelerated action, and empowered communities are essential to avoid cascading Earth system tipping points and achieve lasting, transformative change.

We assess the reversibility of Antarctic sea ice loss through Coupled Model Intercomparison Project Phase 6 experiments and quantify the inter-model differences Inter-model differences in sea ice...

The polar regions are undergoing alarming climate changes, particularly in Antarctica, where ice loss is accelerating. A study warns that geoengineering solutions are unlikely to be effective, distracting from essential emission reduction efforts. Immediate, evidence-based actions are necessary to combat climate change and achieve net-zero emissions to stabilize global temperatures.

But curiosity-driven stupidity may take us there

A review of the five main methods proposed for cooling down the poles or slowing the loss of ice concludes they are all wildly impractical, wouldn't work, or both

To keep Earth habitable, humanity must recognize the value of Antarctica and seek to save it from irreversible damage.
