[edit] Location

[edit] "as far north as 80°N."

Could somebody give a realistic idea of how far north this is? Like give the name of a country at that level? Robinoke 10:31, 25 Feb 2005 (UTC)

[edit] Transgression

Did Paleocene-Eocene Thermal Maximum caused any notable transgression of oceans onto the continents? It is very interesting question with respect to global warming and rising of oceans. Stepanovas 10:42, 17 December 2005 (UTC) The Cretaceous and the Paleocene did not have polar ice caps, so there were no ice reserves to melt and raise sea levels worldwide. Warmer oceans do expand somewhat. --Wetman 05:51, 27 July 2006 (UTC)

What is the Antarctic Ocean? I assume they meant Arctic.

I think you are right too, although I am not an expert, but I do recall (see my note below) Tim Flannery's preoccupation with the Arctic - not the Antarctic - when discussing this same PETM event so I have changed it myself. It has been a long time since you posted and no one else has been around to respond or do so. Finally, all of the links similarly seem to refer to the north pole i.e. northern oceans also!

[edit] Hmm?

I guess this could represent the runaway greenhouse effect ? 91.153.61.172 07:40, 31 August 2007 (UTC)

I guess it couldn't, because the greenhouse effect did not, in fact, run away. -- Zimriel (talk) 02:32, 16 May 2008 (UTC)


[edit] Causes

[edit] Asteroid Impact(s)

Tim Flannery mentions this extinction event early in his book on global warming The Weather Makers refering to evidence/research that suggests a nothern hemishpere (north atlantic i believe) oceanic impact or impacts that heated the ocean and/or directly heated oceanic/coastal methane and methane hydrate reserviors. Yet nowhere is this eveidence/theory however briefly mentioned in the article? Maybe I will come back and do so when I have a hardcopy to cite with the reference (I currently only have an audiobook). If anyone knows anything or has it also then please include it. Interestingly Image:Extinction Intensity.png doesn't include a -55M peak either. Regards, Mattjs 04:15, 21 February 2007 (UTC)

Looks like someone else agreed with me but this time a comet. Would be a nice addition if it came with a supportable reference - guess I will just have to find it in The Weather Makers again and then add and/or ammend this users edit. Mattjs 17:13, 22 February 2007 (UTC)


[edit] Ecology

[edit] The "Norwegian Blue"

During a hot period at 55 mya there is, now, in Denmark of all places, a wingbone of the first parrot.[1] Any chance of seeing this in the article? Seems to me to be topical - unless we are assuming two warming periods within 800,000 years of each other, one of which affected only Denmark. I posted it a mite too fast and perhaps in the wrong section of this article. I was going to wikify my primary source but someone edited it out faster than I could fix it. Anyway, my link here is the better-formatted version I'd posted in the parrot page... -- Zimriel (talk) 02:32, 16 May 2008 (UTC)

[edit] Dead link

During several automated bot runs the following external link was found to be unavailable. Please check if the link is in fact down and fix or remove it in that case!
