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.

The buttresses of ice frozen around Antarctica's edges, hundreds of meters thick in many cases, are also in the sea, but they can act like doorstops and — once moved out of the way — can allow huge volumes of ice on the continent (in theory) to move toward the sea more easily.

Thus the sea ice volume will not fall straight to zero on the PIOMAS graph, but curve round to the right.

«Preliminary data also indicate 2008 may represent the lowest volume of Arctic sea ice on record, according to the researchers.

On decadal and longer time scales, global mean sea level change results from two major processes, mostly related to recent climate change, that alter the volume of water in the global ocean: i) thermal expansion (Section 5.5.3), and ii) the exchange of water between oceans and other reservoirs (glaciers and ice caps, ice sheets, other land water reservoirs - including through anthropogenic change in land hydrology, and the atmosphere; Section 5.5.5).

Sea ice extent, thickness and volume are all normal, yet the Flat Earth Society of climate scientists drones on endlessly about an ice - free Arctic — which they will never live to see.

In summary the melting of land ice floating on the ocean will introduce a volume of water greater than that of the originally displaced sea water, hence raising the water level a little.

In that case it is important to have a more precise statement, so I went back to check the reference Journal of Marine Systems Volume 48, Issues 1 - 4, July 2004, Pages 133 - 157 Sea ice from the Kara Sea region reaches Fram Strait from 2 to 4 years (min 2 years) on average, and while sea ice from the Laptev Sea takes roughly 4 — 6 years (min 3 years) to reach Fram Strait»... from the East Siberian, Chukchi and Beaufort seas within 6 — 10 yeaSea ice from the Kara Sea region reaches Fram Strait from 2 to 4 years (min 2 years) on average, and while sea ice from the Laptev Sea takes roughly 4 — 6 years (min 3 years) to reach Fram Strait»... from the East Siberian, Chukchi and Beaufort seas within 6 — 10 yeaSea region reaches Fram Strait from 2 to 4 years (min 2 years) on average, and while sea ice from the Laptev Sea takes roughly 4 — 6 years (min 3 years) to reach Fram Strait»... from the East Siberian, Chukchi and Beaufort seas within 6 — 10 yeasea ice from the Laptev Sea takes roughly 4 — 6 years (min 3 years) to reach Fram Strait»... from the East Siberian, Chukchi and Beaufort seas within 6 — 10 yeaSea takes roughly 4 — 6 years (min 3 years) to reach Fram Strait»... from the East Siberian, Chukchi and Beaufort seas within 6 — 10 years.
