Re: Late Cretaceous Arctic Climates

I've been talking about the extremely good possibility for at least 
seasonal ice at the poles during the K for years. So, I for one am glad 
to see yet another article that says this was probably the case. And 
Guy, there's really every reason to believe that the South Pole was the 
same... especially since, if memory serves, there were already a good 
deal of elevated mountain ranges at the time, and land completely cut 
off from the ocean. Isolate elevated land masses where the sun doesn't 
shine for part of the year and ocean currents that are obstructed due 
to those very same land masses, and you will get ice. I don't think 
there is really any way to avoid it. Similar situation goes for the 
North Pole as well (not so much the mountains, though there were some 
such as the Brooks Range in AK for example, but definitely the ocean 
current situation).

Interesting... wonder if the southern Polar oceans were similar?
