I'm not a paleoclimatologist, so I look more into the future than the past, but certainly all of us understand the ice age and the changing conditions we've seen. We had ice times and non-ice times—we all know that. The difference now is how rapidly it's happening, not that it's happening.
It doesn't surprise any of us scientists that we are seeing a warming period. We've seen cooling periods, but the timeline that it's happening in is way faster than we've ever seen before. There are certain periods.... The last ice area has been here for over two million years, and we expect that to be gone within the next 20 or so.
I'm not sure that I answered your question, but I'm not a paleoclimatologist either.
