The ground under your feet is moving. Right now, at about the speed your fingernails grow, and it has been … Read more…
Scientists studied granitoids from the Kangding area in the southeastern Tibetan Plateau, using new elemental and isotopic data, including the first silicon isotope measurements for these rocks, to trace how the plateau’s crust grew eastward over the last 35 million years. The granites fall into two groups, and one of them shows a temporary shift … Read more…
During the Cenozoic Era, the ocean’s meridional overturning circulation (MOC) has alternated between North Pacific and North Atlantic sinking modes. The Miocene Climatic Optimum (17.0–14.7 Ma) is a key interval for reconstructing this history because there is partial and inconclusive evidence for both MOC modes during this period. Here, we use the GFDL CM2.1 coupled climate … Read more…
