This is not climate related, as such, but a geological conumdrum - see www.sciencenews.org/view/generic/id/351788/description/News_in_Brief_Mil... ... this happened in the Pliocene, which in geochronology directly precedes the Pleistocene and as a result of uniformitarianism is duly dated millions of years ago. The evidence of ice melt in Antarctica comes from sea floor sediments 300+km from the continent. The sediment core was rich in algae, a sign the ocean was warm.
At http://malagabay.wordpress.com/2013/07/13/the-inflating-earth-sea-level/ ... Tim Cullen takes a look at sea levels in the context of the Inflating Earth hypothesis. What he says is interesting to all geologists and anyone else that might have faith in the science involved. Local mean sea level is defined on the height of the sea with respect to a land benchmark, averaged over a period of time, long enough that fluctuation caused by waves and tides are smoothed out.
In a follow up post on July 3rd Tim Cullen expands further on the geological jigsaw puzzle associated with chalk formation - and includes on this occasion the flints found within the chalk - go to http://malagabay.wordpress.com/2013/07/03/the-chalky-cretaceous-2-the-ey...
It's a fact that chalk formed extensive beds in the Cretaceous but nowhere in the world is there evidence of chalk being formed today. Limestone, which is closely related to chalk, being formed also of the shells of marine life, was generally laid down earlier than the chalk. For example, the limestone rocks of the Peak District and the Yorkshire Dales is derived from former coral reef systems when Britain was situated in warmer climes.
At www.geneticarchaeology.com/research/Chalking_up_a_marine_blooming_alga_G... ... chalk deposits are formed from the white shells that envelop single celled photosynthetic alga known as Ehux, a coccolithopare with an exo skeleton made of calcium carbonate. Ehux, and related life forms, are the bedrock of most ocean food chains. Phytoplankton biomass exceeds that of all marine animals combined.
Well, that is the headline at http://phys.org/print290673740.html .... but it emerges that what has been found is an active tectonic zone to the west of Portugal - or rather, a reaffirmation that a fault line exists out in the sea which was responsible for the 1755AD Lisbon earthquake and tsunami.
The last of the three posts goes where it naturally weaves a path - http://malagabay.wordpress.com/2013/06/16/the-inflating-earth-4-gravity/ .... and leads from the equatorial bulge to the question of gravity. For this he goes to www.dinox.org which I mentioned a couple of days ago, the web site of Stephen Hurrell (dinosaurs and the expanding earth) - so you can have two bites of the same cherry.
In the next of his posts on the Inflating Earth model, Tim Cullen turns to the equatorial bulge - how does this feature fit into the Expanding Earth hypothesis - see http://malagabay.wordpress.com/2013/06/14/the-inflating-earth-equatorial...
I seem to have got stuck on this theme of the Expanding Earth theory but here are another three pieces to look at by those still awake, or vaguely interested in the subject. At http://malagabay.wordpress.com/2013/06/13/the-inflating-earth-antarctica/ ...

The David Pratt article at www.ncgt.org ended in a bit of a drizzly fizzle as part of the Expanding Earth hypothesis includes polar wander - and he thought it was possible for scientists to track former pole positions. He claimed these began in Africa but gradually tracked southwards as the earth expanded. In other words, the Expanding Earth model is uniformitarian in concept, and simply a variation, of sorts, of the Plate Tectonics model of consensus academic geology.
