Hi all
Well I have my own article on where the heck is global warming? We are asking that here in
Boulder where we have broken records the past two days for the coldest days on record. We
had 4 inches of snow. The high the last 2 days was below 30F and the normal is 69F, and it
smashed the previous records for these days by 10F. The low was about 18F and also a
record low, well below the previous record low. This is January weather (see the Rockies
baseball playoff game was canceled on saturday and then played last night in below freezing
weather).
Trenberth, K. E., 2009: An imperative for climate change planning: tracking Earth's global
energy. Current Opinion in Environmental Sustainability, 1, 19-27,
doi:10.1016/j.cosust.2009.06.001. [1][PDF] (A PDF of the published version can be obtained
from the author.)
The fact is that we can't account for the lack of warming at the moment and it is a
travesty that we can't. The CERES data published in the August BAMS 09 supplement on 2008
shows there should be even more warming: but the data are surely wrong. Our observing
system is inadequate.
That said there is a LOT of nonsense about the PDO. People like CPC are tracking PDO on a
monthly basis but it is highly correlated with ENSO. Most of what they are seeing is the
change in ENSO not real PDO. It surely isn't decadal. The PDO is already reversing with
the switch to El Nino. The PDO index became positive in September for first time since
Sept 2007. see

extremely disappointing to see something like this appear on BBC. its particularly odd,
since climate is usually Richard Black's beat at BBC (and he does a great job). from
what I can tell, this guy was formerly a weather person at the Met Office.

We may do something about this on RealClimate, but meanwhile it might be appropriate for
the Met Office to have a say about this, I might ask Richard Black what's up here?

Hi all. Any of you want to explain decadal natural variability and signal to noise and
sampling errors to this new "IPCC Lead Author" from the BBC? As we enter an El Nino year
and as soon, as the sunspots get over their temporary--presumed--vacation worth a few
tenths of a Watt per meter squared reduced forcing, there will likely be another dramatic
upward spike like 1992-2000. I heard someone--Mike Schlesinger maybe??--was willing to bet
alot of money on it happening in next 5 years?? Meanwhile the past 10 years of global mean
temperature trend stasis still saw what, 9 of the warmest in reconstructed 1000 year record
and Greenland and the sea ice of the North in big retreat?? Some of you observational folks
probably do need to straighten this out as my student suggests below. Such "fun", Cheers,
Steve

Steve,
You may be aware of this already. Paul Hudson, BBC's reporter on climate change, on Friday
wrote that there's been no warming since 1998, and that pacific oscillations will force
cooling for the next 20-30 years. It is not outrageously biased in presentation as are
other skeptics' views.

BBC has significant influence on public opinion outside the US.


Do you think this merits an op-ed response in the BBC from a scientist?
