We have research that supports it because thats where the funding is. No-one is interested in funding 'anti-global warming' research (I've heard that directly from my lecturers, many of whom are world renown researchers in geology).
Whether we are over due for an ice age or not is a matter of contention. There is no set amount of time that an interglacial period must last for - and how are we meant to tell what is going to happen in the future of our planet anyway? We don't know exactly what caused the previous ice ages, so unless we can time travel back then and find out, we do not know what we have to look for in order to determine when the next period of glaciation is going to occur. As the temperature increase stands, we are in an interglacial period.
Another thing worth mentioning here is the Little Ice Age and the associated Medieval Warm Period. If this is taken as the most recent "ice age", for all of its much shorter time span, than the usual glaciation, then we are most definitely coming out of an ice age at the moment.
Its not a fair test unless they use all of the data. Selecting which data are used can make it a biased test.
How can we know the future? How can we say that this is not how Earth is meant to be evolving?
One of the things that people I know point out when we get into this sort of discussion at uni, which happens fairly often, and will happen more often with the coming election and people getting frustrated about all the 'climate change' ads on TV, is that the human race is going into another 'Dark Age' of knowledge. People are lapping up what they're told, and not questioning. People - scientists, researchers etc. - are just doing research where the money is, and where is seen to be a popular topic at the time.
I remain a skeptic on an anthropogenic cause for climate change. Earth has had a pattern of climate change - and most likely glaciation (although we do not have the rock record for these due to erosion) - for its entire life. Its not going to change simply because we are here, or because we are trying to change it. This is what evolution is all about - adapting to your environment, which is something that the human race seems to struggle with. We adapt our environment to ourselves, rather than the other way around.

Because of the favorable site location, continuous monitoring, and careful selection and scrutiny of the data
