Notes

Abstract:
Only when climate records at centennial to millennial scales became available did the complexity of glacial terminations become apparent. Early low-resolution palaeoclimate reconstructions suggested a rapid and relentless meltdown. But at a closer look, an interhemispheric asynchrony emerged. Warming began in Antarctica around 18,000 years ago, which was interrupted by an abrupt reversal about 14,500 years ago. However, this southern cooling was countered by warming in the Northern Hemisphere until it too was interrupted by 1,000 years of cooling. Full interglacial conditions in both hemispheres were only reached after 11,700 years ago. ( English )
