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. |

Its a Copenhagen Special release considering the timing- Hide quoted text - - Show quoted text - 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 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! Astra |

Astra- Hide quoted text - - Show quoted text - 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. |
