Changes in ocean heat content(OHC), salinity, and stratification provide critical indicators for changes in Earth’s energy and water cycles. These cycles have been profoundly altered due to the emission of greenhouse gasses and other anthropogenic substances by human activities, driving pervasive changes in Earth’s climate system. In 2022, the world’s oceans, as given by OHC, were again the hottest in the historical record and exceeded the previous 2021 record maximum.According to IAP/CAS data, ...  相似文献   

Upper Ocean Temperatures Hit Record High in 2020

The long-term warming of the ocean is a critical indicator of both the past and present state of the climate system. It also provides insights about the changes to come, owing to the persistence of both decadal variations and secular trends,which the ocean records extremely well(Hansen et al., 2011;IPCC, 2013;Rhein et al., 2013;Trenberth et al., 2016;Abram et al., 2019).  相似文献

Time-scales of Differentiation from Mafic Parents to Rhyolite in North American Continental Arcs   总被引：4，自引：4，他引：4

Young rhyolites and associated lavas and magmatic enclaves fromthe Katmai–Novarupta volcanic system (Alaskan Peninsula),and the Crater Lake and Medicine Lake volcanic system (Cascades)were analyzed for U and Th isotope abundances, as well as majorand trace element concentrations, to investigate the time-scalesof the processes that lead to rhyolite generation in continentalarcs. Basalts and basaltic andesites typically migrate fromthe mantle to the surface within several thousand years. Variationsin (²³⁰Th)/(²³²Th) and (²³⁸U)/(²³²Th) ratios with SiO₂ concentrationsin intermediate lavas appear to result from crystal fractionationcombined with assimilation of recently crystallized magmas.These data also suggest that  相似文献
