Here's probably all you need to know.

Note the temperature today is ~6 deg *below* the peak
temperature of 130,000 years ago, ~3 deg below the
peak of 240,000 years ago, ~5 deg below the peak of
340,000 years ago, and ~2 degrees below the peak of
410,000 years ago. As far as natural global warming
cycle peak temperatures go, the present one is
relatively cool - plus the fact that it peaked 8000
years ago indicating that we are already in the
next ice age cycle. Just ask the folks in Denver. :-)
