INTERGLACIAL GLACIAL

The glacial/interglacial changes in atmospheric methane concentrations are character- ized by a strong increase from 350 ppbv during the Last Glacial Maximum (LGM) to values as high

Glacial/Interglacial Variation — Termination I and the last.. IPCC: Radiative forcing — the process.. IPCC: Global responses — the effect.. IPCC: Anthropogene versus natural..

The results suggest that •øBe rain rates and authigenic U concentration cannot serve as quantitative paleoproductivity proxies because they have also been influenced

Besides the global area available for vegetation (which is correlated to sea level and the size of continental ice sheets), temperature, precipitation and atmospheric carbon dioxide

Here we used a coupled atmosphere/biosphere/ocean box model of the global carbon cycle to quan- tify changes in pCO 2 and δ 13 CO 2 observed in Antarctic ice core records.. To this

Using COSMOS model to simulate five different climate states, we found that the existence of the Laurentide Ice Sheet and higher elevation of Greenland Ice Sheet during
