World at risk of losing ice sheet, glaciars
Down To Earth
|June 16, 2025
THE ANTARCTIC ice sheet, which has the biggest potential for sea-level rise upon melting, may be at or very close to a tipping point, says a study published in Communications Earth and Environment on May 30.
-
The study says it has confirmed "hysteresis" behaviour in the ice sheet, which means the melting process has entered a point at which it will continue even if global warming is contained. It says that even 0.25°C rise in ocean temperatures― or even zero warming over the current levels-in the West Antarctic ice sheet will lead to a sea-level rise of 4 m

1,500 days, and an alarm for new climate
SEASONS ARE the compass that guide humans to survive and thrive as a society. What happens if seasons lose their distinct character and predictable rhythm? This is no longer a theoretical question. The Earth is entering a new climate regime, its atmosphere now saturated with greenhouse gases at levels without precedent in human history. And the earliest sign of this shift is the near-dissolution of familiar seasons; all merging and dissipating like the pupa inside the chrysalis, but, not to give birth to that mesmerising butterfly.
