Global temperature has warmed to near record levels in 2010 say climate scientists from the Met Office and the University of East Anglia. Provisional figures for the three main global temperature datasets put 2010 on track to become first or second warmest in the instrumental record.
The preliminary figure for January to October 2010 is 0.52 °C above the long-term average on the Met Office – Climatic Research Unit (HadCRUT3) dataset, placing it equal with the record-breaking 1998.
The Met Office annual global temperature forecast for 2010, Climate could warm to record levels in 2010, issued at the COP15 talks in Copenhagen, predicted that the year was “more likely than not” to be the warmest year. Dr Adam Scaife, head of long range forecasting at the Met Office said, “The three leading global temperature datasets show that, so far, 2010 is clearly warmer than 2009 despite El Niño declining and being replaced by a very strong La Niña, which has a cooling effect.”
Although La Niña has stabilised, it is still expected to affect global temperature through the coming year. This effect is small compared to the total accrued global warming to date, but it does mean that 2011 is unlikely to be a record year according to the Met Office prediction based on the three main datasets. Nevertheless an anomaly of 0.44 °C is still likely — with the range very likely to be between 0.28 °C and 0.60 °C. The middle of this range would place 2011 among the top 10 warmest years on the record.
Dr Vicky Pope, the Met Office’s head of climate science advice said, “Our annual prediction of global temperatures for the next year combined with our monitoring of the observed climate helps people to put the world’s current climate into context.”
