Tropical Warm Pool Sparks Temporary Record Ice Gain in East Antarctica
A tropical-warm-pool–driven circulation change temporarily boosted snowfall in East Antarctica, adding a record 695 billion tons of ice from 2021–2023—the largest gain detected by GRACE—yet it does not reverse the continent’s long-term ice loss (about 140.5 billion tons per year), highlighting a recurring tropical linkage that can influence Antarctic mass balance for several years.
