Este estudio muestra que esos cambios eran más lentos de lo que se creía, lo que cambia cómo se calculan los riesgos para el Atlántico. Para los argentinos, eso pesa en los pronósticos de largo plazo que orientan el campo y la planificación del país. Lo que parecía un salto repentino era, en realidad, una transición que tomaba generaciones enteras.","quienFirma":"Science (investigadores de China e India)","confianza":"revisado","consulta":null},"sello":{"hash":"1d62267169fd8bce74739c794e9c524e9ec2de459f3d82e9ad4d66f9335789c1","sello":"19c8dca9218eb9d2ccb2f283705090bda64ad1526e9bcba5a3c294e49e354ac1","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6615812,"aleatorio":"53309ffb523dda464efef7696697bb07fb3ddfc89b2faa5ab44eeb5ee729ab49","tiempo":"2026-11-05T19:03:00.000Z"},"nist":{"cadena":2,"pulso":2014840,"salida":"6245F4C7F2C4E90F4D14982B4F1EB6F7FE41DED8FFE66B3B4EA84D9C744769EBCAA811777D7B15B5E94ABF5103158CEB2E9D1E52675E4CCE1056B23D6EA3E960","tiempo":"2026-11-05T19:02:00.000Z"},"noAntes":"2026-11-05T19:03:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Nov  5 19:03:38 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Ice-age abrupt climate shifts were not as fast as thought, new study finds","descripcion":"New high-resolution speleothem records from China and India, together with isotope-enabled climate models, show that abrupt glacial ocean circulation recoveries took centuries, not decades—a finding with important implications for how we assess future Atlantic circulation change.
