Although on average the sediment buildup follows sea level, it sometimes lags behind when sea level rises rapidly, or catches up when sea level rises more slowly.

Since the volume of ice at risk under BAU is within a factor of two of the volume of ice at risk during a deglaciation under orbital forcing, while the forcing is much more rapidly applied under BAU, looking at sea level rise rates in the paleo - record might actually be considered a search for lower limits on what to expect if reticence did not run so strongly in our approach.

These include increases in heavy downpours, rising temperature and sea level, rapidly retreating glaciers, thawing permafrost, lengthening growing seasons, lengthening ice - free seasons in the ocean and on lakes and rivers, earlier snowmelt, and alterations in river flows.

This timescale of melt was also confirmed by the ANDRILL record (Naish headed at least one of these expeditions) and another paleo record showing that the sea level rose rapidly around a corresponding time.

Among these physical changes are increases in heavy downpours, rising temperature and sea level, rapidly retreating glaciers, thawing permafrost, lengthening growing seasons, lengthening ice - free seasons in the oceans and on lakes and rivers, earlier snowmelt and alterations in river flows.

Finally, there is another way how ice sheets can contribute to sea level rise: rather than melting at the surface, they can start to flow more rapidly.

If we lose them rapidly then there would be a small rapid sea - level rise, major rapid local effects to do with huge quantities of meltwater, and an albedo feedback effect.

However, as Timothy explained in # 121, in addition to the direct sea level rise that occurs when ice shelves melt, there is a much larger secondary effect, in that ice shelves act as a brake, greatly reducing the rate of flow of the glaciers behind them from the land to the sea; and when ice shelves melt, the rate of glacier flow increases quite rapidly.

Just as with Antarctica, Greenland's ice sheet contribution to rising sea levels is continuously and rapidly growing.
