Is it true that 9 out of 10 of the warmest years ever recorded occurred since 1990? If so, when was the one prior to 1990?

    Globally (through 2007), 7 of the 8 warmest temperatures on record have occurred since 2001 and the 10 warmest years have occurred since 1997. There were high temperatures in the early 1940s, but nothing like what we are seeing today.
