I'm not sure what you're asking me to find evidence to "refute." The idea that the Earth was warmer at some point in the past than it is now? Of course it has been. What does that prove or disprove? The "question" is whether industrialization is at the root of the global warming that's happening now.

But consider that 2 degrees Centigrade that marks the difference between now and the Eemian stage. Conservative estimates are that, if everything we do stays the same, a quarter of that difference will be erased by 2030, and it will keep going from there.
Imagine the coasts with seawater a significant amount of that eight meters higher.

The average (although much more in some parts of the world) temperature has risen a degree centigrade since the 1880s and has risen at a faster rate since the middle of the 20th Century. That's just not a geological pace.

Your cut and paste seems to come from a social science book. The author apparently thinks we're still in the Pleistocene. I've never seen that one before. He's apparently mixing up the Pleistocene and the "ice age." They aren't the same thing.
Technically, we're still in an ice age becuse there are large sheets of glacial ice, especially on the poles. But the Holocene, geologically speaking, has come after the Pleistocene.

The NOAA, the IPCC, the National Academy of Science and on and on see the link between human activity and increased temperatures. You might want to take a look at what they have to say about it instead of pasting sociology books off of Wikipedia.
