Antarctic ice is melting at a startling pace, and the West Antarctic Ice Sheet is one of the greatest sources of uncertainty in climate projections. Researchers thought westerly winds were accelerating ice loss, but a new study flips the narrative by 90 degrees, pointing instead to winds from the north.

The Time2Graze project will develop and equip farmers in Latin America with tools that assess pasture availability to identify the optimal time to graze livestock 

Supported by the Global Methane Hub, the Time2Graze project is co-led by the World Resources Institute (WRI), the Alliance Bioversity International and Center for Tropical Agriculture (CIAT), the National Agriculture Research Institute of Uruguay (INIA) and WWF. 

While the initial focus for the Alliance is on Colombia and Brazil, the project aims to progressively expand its reach across tropical Latin America and the Caribbean. 

Asymmetric tropical ocean warming since 1999 has reshaped the Madden–Julian Oscillation (MJO), a key climate rhythm driving rainfall, monsoons, and storms worldwide. Researchers using satellite and reanalysis data found the MJO now moves faster over the Indian Ocean and Maritime Continent but slows over the western Pacific. These shifts show how uneven ocean warming reorganizes tropical convection, with vital implications for improving climate models, forecasts, and resilience to extremes.

Precipitation δ¹⁸O provides important insights into the decadal variability of the East Asian monsoon. Using both isotope-enabled climate simulations and reconstructions, this study found a quasi-11-year cycle in precipitation δ¹⁸O (δ¹⁸O_p) across the monsoon region. The cycle was driven by enhanced solar activity, which strengthens the Walker circulation and increases moisture transport from the equatorial Pacific. The results have suggested that the quasi-11-year δ18O_p cycle primarily reflects shifts in moisture sources driven by solar activity. The findings were recently published in SCIENCE CHINA Earth Sciences.
