The actual world temperature record shows that since
the end of the Little Ice Age around 1860, there have been 
alternating 20-30 year long cycles of warming and stable 
(or slightly cooling) temperatures like this:

This suggests we are currently 13 years into a period 
of temperature stability that should last until sometime 
between 1919 and 2029.
