MetO/Hadley centre global temperature forecast 2010.
 
http://www.metoffice.gov.uk/corporat...20091210b.html

The Hadley centre are forecasting record global temperatures next
year.

I think along very similar lines and I've been writing as such since
the start of this El Nino. *If* this El Nino continues through to the
Boreal summer, 2010 may well be the warmest year on record, beating
1998. The effects are already being seen in the global temperatures
from June 2009. The 12 month period from June 2009 - May 2010 may well
end up the warmest 12-month period on record - it is already well on
the way - and this warmth may well continue to the end of 2010 *if*
the El Nino continues.

Ifs and buts, I know and they are reflected in the Hadley Centre's
written forecast. This forecast of +0.60C above the 1961-90 average
would leave 2010 global temperatures really quite hugely above
1998/2005 (At 0.08C it doesn't sound "hugely above", but that kind of
value would erase the 1998 record by some distance) and it is an
extreme forecast. To forecast record global temperatures with an
extended solar minimum is a fair old leap in the dark. A real stick-
your-head-over-the-parapet forecast, with, if you are a sceptic, every
chance of going wrong. In fact, from a sceptics view, surely this
should not happen? I'm sure the "can't trust anything they say"
rubbish will flow swiftly, as will comparisons to the MetOs only
reasonable seasonal forecasting which are simply not valid.

At present, I agree with what they are saying - but it does depend on
the persistence of this El Nino event.

Last year the global forecast was released a little later, at the end
of December, John, that's true!

However the forecast is likely to be jpretty close. The MetO forecast
that 2009 would be in the top 5 warmest years on record, with an
outcome temperature of 14.44C, just over 0.4C above the 1961-90
average. It won't be far away from that. Remember also that the year
started with a weak La Nina, so one certainly wouldn't expect 2009 to
be on a par with the global temperatures in 1998, or 2005. In fact,
with the influence of a declining La Nina for the first few months of
the year (and a solar minimum and a negative PDO), it could be argued
that 2009 shouldn't be *anywhere near* the top 5 warmest on record. I
won't repeat some of the sillier Internet forecasts of a "super" La
Nina developing and 2009 being the start of a worldwide cooling. I
think the denialist blogosphere has put that back yet another
year.........*))

I seem to remember saying this last year, but I really do wish the Met

I wonder if the very cold conditions over a lot of Europe/Russia expected in
the next half of the month will make a difference or do the El Nino SSTs
dominate? I would prefer to see land figures only when talking about
warmest/coldest as that's where humans live - on land. Are there any
datasets available for land only?

The use of "confirm" and "expected" in the same sentence seems designed
to confuse, though.

Well, it doesn't really matter anymore. Your certifiable prime
minister is going to chuck 1.5 billion pounds of your money at
"climate change", and give it to some third world dictatorship or
other despots who don't need it, and will probably blue it all on
weaponry - I see they've started squabbling in Copenhagen already.
Completely and utterly stark raving bonkers. Not much chance of you
lot beating the recession at this rate, methinks. Are your belltowers
in order? Mind you, Sarkozy's just as mad. Will the world stop
warming/cooling? Will it buggery....

Remember your spherical geometry. Half of the earth's surface is within 30
degrees north and south of the Equator and a substantial part of that is in
the Pacific Ocean (where El Nino lives). Only 15% of the earth's surface is
north of 45 degrees north and how much of that is Europe and west Russia?

This is why the tropics often dominate in such matters. There is just so
much more surface area there.

I think that you will find that the Met Office/Hadlet centre
temperature records that have been released as being "the real raw
data" are actually flawed by systematic error.
If you look at the map of distribution of the recording stations, you
will quite clearly see that of the 1500 locations, most of them are in
the USA and other traditionally industrialised areas, and based near
to either big cities, or airports near to cities. And that has been
happenning for the last 100 years or so? Modern day urbanisation/
development, which has led to massive urban heat island effects such
as the generation of "country breezes".

So as you can imagine, systematic error has been drawn into the mix,
such that the temperatures recored do not show a typical spatial
"unbiased" recored of events...in other words they are showing warming
where there isn't any.
The night time minima willalso be biased on the warm side, as the
cities do not cool overnight as the surrounding areas do.

Make no mistake, the only way to stop the promugation of such crap
data sets is to start again, this time totally ignoring any stations
globally which are within a certain radius of modern day urbanisation.

If any other climate scientists are reading this,please re-run your
models without the cities bias, then post here what you observe!

No, No and No again.

The NOAA dataset is over 7,000 stations, The usefulness of the
stations and the accuracy of the record has been checked rechecked and
is accepted (OK, you don't and a few others) by all. The checking and
especially the corellation with other global temperature measures has
been done in response to sceptic Adjustments have been made to
compensate for the growing urban influence on a minority of sites.
It's the same with Hadley and the GISS. The 2 satellite measures
correlate very well with all three land based measures for the 30
years of their use and the 3 land-based measures correlate with each
other. In any case, the absolute measures, though statistically
completely valid, are less important than the trends which are shown
by all 5 datasets.
