Me, I blame the sun as usual. Solar cycle 24 is very late.

Martin van Calmhout - a formidable Dutch science journalist - reviewed
this article in Science in yesterday's Volkskrant. One of the authors -
Henk Brinkhuis - is a professor at Utrecht.
It talks about a 5C drop in global temperature over 100,000 years some
34 million years ago during the Eocene-Oligocene Climate Transition.
The paper is based a new technique for recovering paleolthic
temperatures, by measuring the the relative concentrations of
particular organic chemicals in the cell wall of single cell fossils,
which allowed the authors to clarify what what actually going
on during the transition, when the Antartic ice-sheet seems to
have made its appearance
The authors can't come up with an explanation for why it happened
as fast as it did. Explanations for the transition do exist, but they
seem to envisage a slower cooling.

No doubt the denialists will blame the sun, as usual.
Regarding cooling since 2000:

This is nothing like anything weve seen since 1950, Kyle Swanson of
the University of Wisconsin-Milwaukee said. Cooling events since then
had firm causes, like eruptions or large-magnitude La Ninas. This
current cooling doesnt have one.

This is an incomplete quotation. For the full text, look at
http://wattsupwiththat.com/2009/03/02/cooler-heads-at-noaa-coming-around-to-natural-variability/
where Swanson is quoted as going on to say
"Swanson thinks the trend could continue for up to 30 years. But he
warned that its just a hiccup, and that humans penchant for spewing
greenhouse gases will certainly come back to haunt us.
When the climate kicks back out of this state, well have explosive
warming, Swanson said. Thirty years of greenhouse gas radiative
forcing will still be there and then bang, the warming will return and
be very aggressive.
which isn't quite the message that your deceitful text-chopping is
intended to convey.
If these guys are saying they don't know the mechanism for the current
cooling then they don't know enough to predict 30 years or even 10
years ahead.
