Late Miocene climate evolution provides an opportunity to assess Earth's sensitivity carbon cycle perturbation under warmer-than-modern conditions. Despite its relevance for understanding the system, driving mechanisms underlying profound and changes – including enigmatic cooling from 7 5.4 million years ago remain unclear. Here, we present magnetic geochemical paleoceanographic proxies a hydrogenetic ferromanganese crust retrieved in northwestern Pacific Ocean. Our results indicate striking 50% surge deep ocean phosphorus concentrations occurred 4 ago, synchronous with enhanced oxygen consumption. Employing global biogeochemical model, show that increased continental weathering, without concurrent rise silicate contributed decline atmospheric CO2 associated over Miocene. This suggests prominent decoupling of weathering during major cycling event last 10 years. West new insights Cooling weathering.

The uplift of the Qinghai-Tibet Plateau is one greatest geological events on Earth, pivotally shaping biogeographic patterns across continents, especially for migratory species that need to overcome topographical barriers fulfil their annual circle. However, how influences animal migration strategies remains largely unclear. We compare current flyways 50 avian migrating plateau with those reconstructed before as a counterfactual. find major effect changing directions from latitudinal longitudinal. monsoon system generated by rather than high elevation per se shapes changes. These findings unveil mechanism an important global event has influenced birds, yielding testable hypotheses observed distributions emerge.
