No doubt the denialists will blame the sun, as usual.

Regarding cooling since 2000:

/quote

?This is nothing like anything we?ve 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 doesn?t have one.?

/end quote- Hide quoted text -

This  is an incomplete quotation. For the full text, look at

http://wattsupwiththat.com/2009/03/02/cooler-heads-at-noaa-coming-aro...

where Swanson is quoted as going on to say

"Swanson thinks the trend could continue for up to 30 years. But he
warned that it?s 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, we?ll 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.

I chopped the wild fantasy.

What you think is wild fantasy, because you don't understand enough to
follow the elementary loic involved.

I understand the AGW argument, it just isn't settled or science.


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.

Actually, they do know the mechanism - ocean currents are moving heat
around, along with the atmospheric circulation.Unfortunately they
don't know enough about the ocean currents to be able to make short
term climate predictions. People are busy sinking strings of flow and
temperature sensors in the oceans in order to get a more detailed idea
of what is going on, but there aren't yet enough of them in place to
give all that much information.

That's a crap argument I've seen many times. Moving the heat around
doesn't affect global temperature. X joules of heat on the planet is X
joules whether it's in the ocean or the atmosphere.

The top 6 metres of the oceans store as much energy as the whole
atmosphere. The oceans account for 90+% of energy storage. Anyone who
claims AGW without having meassured the oceans properly is an idiot.


Predicting the broad long term effect of more carbon dioxide in the
atmosphere is easier - the surface of the earth is going to get warmer
- than precisely predicting which bits are going to get warmer and
when.


Easier and almost irrelevent. If ocean currents can more than
compensate for CO2 for the next 30 years, according to Swanson, then
CO2 forcing isn't much to write home about.

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

But you are a denialist, and addicted to explanations wihich don't
produce useful predictions.

The AGW climate predictions up until the last couple of years were for
continuous warming. Can't say their predictions have been accurate or
useful.
