摘要: Large, abrupt shifts in the l8O/16O ratio found Greenland ice must reflect real features of climate system variability. These isotopic can be viewed as a result air temperature fluctuations, but determination cause changes—the most crucial issue for future concerns—requires detailed understanding controls on isotopes precipitation. Results from general circulation model experiments suggest that sources precipitation varied with different states, allowing dynamic atmospheric mechanisms influencing core isotope shifts.
