Your point?
Edit:
"FSM my point is shouldn't we be worrying about ice-ages not global warming"
No we shouldn't, you are just being an "alarmist" ;)
You do realize that your link shows a time frame of 425,000 years. If you were to stretch out that graph to a scale in which you could actually see a human lifetime, the lines would be close to horizontal.
< Where do you get 30.000yrs from? an average interglacial lasts 10 to 11 thousand years, we are overdue.>
Why are we overdue? The little ice age in the mid 19th Century happened right on schedule. Global average temperature was just as low as it was 6,000-8,000 years after any interglacial maximum. If the next ice age is delayed, it would be for one of the following two reasons.
And where did 30,000 years come from? From you graph.
1. We build cities, by accident or design, in key locations, the urban heat island effect will prevent snow from remaining throughout the summer.
2. If there is no mechanism to return the carbon dioxide which we released by burning of fossil fuels.
Why worry about something in 30,000 years fryom now rather than what the next few generations will experience. Again, show how an ice age can occur with any conceivable solar output in the next thousand years and concentration of greenhouse gases.
Hint: it has not happened in the past million years.
EDIt: kano - were overdue according to natural cycles. This is not the case. I'll go with the science on this one. You still have not shown how ice age can occur
EDIT#2: Kano: You don't need a Nobel prize, just some knowledge of climate outside of denier blogs. The cycles and solar output will not do it with the current CO2, unless you can show otherwise. Pointing out to hundreds of millions of years ago with different continents and much fainter Sun is not an answer.. I trust you are smarter than that.
And this mean human activities can't affect the climate over the next few centuries? Ah, I get it now. If you see a fire you don't put it out. You wait for it to destroy the building, then simply rebuild it ...

Not only are interglacial (that we are in right now) very brief periods, in the history of Earths climate, but our interglacial is one of the colder ones.
