Rich,
Help me understand this a bit better. You said "The anomaly is to the average of 1961-1990" but the link you provided says "The January global land surface average was below the 20th century mean for the first time since 1982." and the more detailed link on that page says:
"Estimates of mean monthly global surface temperatures are given below with respect to the 20th century average (1901-2000). The figures are based on 1961-1990 estimates from the University of East Anglia's Climate Research Unit (UEA-CRU). The recently derived 1961-1990 global monthly surface temperature averages represent, in our opinion, the best absolute estimates of global mean temperature and were compiled at UEA-CRU by M. New, P.D. Jones, D.E. Parker and others ."
So I'm confused. Which is it, an anomaly to 1901-2000 or to 1961-1990?
