Icing the North Atlantic
Article Abstract:
Some of the large climate changes in the North Atlantic could have been caused by the advance and retreat of the Laurentide, one of the great ice sheets feeding the region. New research indicates that the ice-rafted-debris signal of the youngest Heinrich event, which took place around 17,000 years ago, is more consistent with a complex and varied reaction to a surge in this ice sheet than with a common reaction of ice masses to an external forcing. This research reopens the debate about the meaning of ice-rafted-debris deposits and of the north-south phasing of deglaciation.

Decadal predictability of North Atlantic sea surface temperature and climate
Article Abstract:
It could be possible to forecast a substantial fraction of the low-frequency variability in North Atlantic sea surface temperature (SST) and sea-level pressure a number of years in advance. It has been established that there is significant decadal predictability of North Atlantic sea SST. This is the result of the advective propagation of SST anomalies and the presence of a regular period of between 12 and 14 years in the propagating signals. This timescale agrees with that which previous researchers have linked with a hypothetical coupled ocean-atmosphere mode.

The North Pacific through the millennia
Article Abstract:
Analyses of climatic variations in the North Pacific since the last glacial age show that climate changes occur on a millennial-timescale. The climatic changes are related to changes in the North Atlantic. These probably occur due to the changes in the far northwestern Pacific, causing ventilation of the Pacific sediments. The changes include rise in temperature of the surface water, formation of ice rafted debris and bioturbation of the sediments.
