  • Ice core derived marine biogenic sulphate does not agree with marine sediment records. Here based on new ice core records spanning the past 720,000 years obtained from Dome Fuji the authors propose that dust contributed a higher percentage of sulphate aerosols than previously thought.

  • Past climate changes in Greenland ice were accompanied by large aerosol concentration changes. Here, the authors show that by correcting for transport effects, reliable source changes for biogenic aerosol from North America, sea salt aerosol from the North Atlantic, and dust from East Asian deserts can be derived.

  • Reconstruction of the Eemian interglacial from the new NEEM ice core shows that in spite of a climate warmer by eight degrees Celsius in Northern Greenland than that of the past millennium, the ice here was only a few hundred metres lower than its present level.

  • A new chronology for Antarctic ice cores has been constructed based on the ratio of oxygen to nitrogen molecules in air trapped in the ice. This seems to reflect changes in local summer insolation, and thus allows the relative timing of changes in insolation and Antarctic climate to be determined. The results show that orbital-scale Antarctic climate change lagged Northern Hemisphere insolation over the past 360,000 years, and that increases in Antarctic temperature at the last four glacial-interglacial transitions took place within phases of increasing Northern Hemisphere insolation.
