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.........*)) |

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.
