Short summary
The West Antarctic Ice Sheet shows opposing snow accumulation trends: decreasing in the west and increasing in the east. Our study reveals that tropical ocean temperature shifts – Pacific cooling and Atlantic warming – drive changes in winds and moisture, boosting snowfall in the east while reducing it in the west. Using ice cores and models, we highlight how distant ocean changes shape Antarctic Ice Sheet, crucial for predicting future sea level rise.

Short summary
Warming in the Indian Ocean during the preceding winter can cause hotter, drier U.S. summers and reduce soybean yields. Our study reveals that temperature changes in the Indian Ocean explain 16 % of variations in U.S. soybean yields. This happens because warmer ocean waters disrupt atmospheric patterns, lowering soil moisture and increasing summer heat during critical growth stages, stressing soybean plants. Understanding this link helps improve crop risk forecasts and protect food security.
Warming in the Indian Ocean during the preceding winter can cause hotter, drier U.S. summers and...
