eocene

For instance in Eocene the climate remained fairly warm and homogeneous (the most uniform in the Cenozoic).

A fairly common horror movie trope, is some Eocene zombiemaker virus, being thawed out of the permafrost.

It sounds like Australia's geographical relationship to Antarctica at the beginning of the Eocene contributed to Antarctica's temperate climate at the time.

Explain the theories behind the warming that led up to the Eocene optimum 49 million years ago and the subsequent cooling after that.

Thermodynamics and heat equations and so on all worked the same way in the Eocene as they do today, and nobody was extracting fossil fuels.

We’re looking at an ecological model - Eocene - not seen for 45 million years in which most mammals may not survive and that includes us.

I think that's wrong, Eocene ended when levels had fallen to roughly 600-700 ppm?

The paleocene–eocene thermal maximum makes for interesting related reading.

The reason for this is that it is a leftover from when the planet was covered in rainforests because it was a lot warmer and wetter in the Eocene epoch.

Most of the time we’re going to have to say that this happened in the Eocene or the Paleocene and we haven’t the foggiest notion of why it happened.

The rainforest being a holdover from the Eocene is news to me, but my understanding was that the climate of the Holocene that we are leaving had weather patterns that facilitated a positive feedback with the Amazon rainforest expansion.

This is a mechanism by which some oil deposits are thought to have formed, and by which a large quantity of biospheric carbon was sequestered during earlier warm spells, refered to as the Eocene Azolla Event.

The Eocene is just before the earth went into a period of "icehouse" climate (that's still going on).

We're currently in an "interglacial" within a period of icehouse climate that has persisted since the late Eocene.

A Google search "Eocene epoch continents" brings up pages suggesting Antarctica's location then was similar to its location now.

During the part of the Eocene this article refers to, the earth was in a "greenhouse" phase, and global temperatures were much warmer than they've been any time since.

In particular he noted: _The last big spike like this was the Paleocene-Eocene Thermal Maximum, about 55 million years ago.

The last period of icehouse climate began just after this, in the late Eocene.

Mammals will have an extremely difficult time surviving another Eocene.
