This year has been the warmest on record in the northern hemisphere, say scientists in Britain.
It is the second warmest globally since the 1860s, when reliable records began, they say.
Ocean temperatures recorded in the northern hemisphere Atlantic Ocean have also been the hottest on record.
The researchers, from the UK Met Office and the University of East Anglia, say this is more evidence for the reality of human-induced global warming.
Their data show that the average temperature during 2005 in the northern hemisphere is 0.65 Celsius above the average for 1961-1990, a conventional baseline against which scientists compare temperatures.
