Quick note today. The World Meteorological Organisation (WMO) has said that 2009 looks set to rank as the fifth warmest year, and the "Noughties" the hottest decade since records began in 1850:

The WMO's final analysis for 2009 isn't due until early next year, but according to Michel Jarraud, secretary general of the WMO, speaking at the Copenhagen conference today: "the decade 2000-2009 is very likely to be the warmest on record. So, in other words, this decade is going to be warmer than the 1990s, which itself were warmer than the 1980s and so on."

The organisation said it estimates the global combined sea surface and land surface air temperature for 2009 (January-October) as 0.44°C ± 0.11°C above the 1961-1990 annual average of 14.00°C.

Above-normal temperatures were recorded in most parts of the continents. Only North America (United States and Canada) experienced conditions that were cooler than average. They went on to say that given current figures, large parts of southern Asia and central Africa are likely to experience their warmest year on record.

Three data sets feed into the WMO temperature analysis. Data from the Met Office/University of East Anglia (subject of the recent e-mail row), along with that from Nasa and the US NOAA (National Oceanic and Atmospheric Administration).

Vicky Pope, head of climate research at the Met Office told the BBC: "In terms of the rates of warming, we do expect the rate of warming to change from one decade to the next, just because of natural variations. So even though there's a long-term warming trend because of global warming, we get things like El Nino happening, things like volcanic eruptions, which mean that we get variations from one year to the next, and one decade to the next."
