The slopes before the El Nino (taken from Jan 1979 to Sept 1997 - the 6th month after ONI first = 0.5 ) are much less that the overall slope. Matter of fact the Annual Min temperatures appear to fall during this time and the Annual Max and Mean look to be slightly +ve. Putting in straight trend lines obscures this interesting and perhaps important observation. This result is quite different from the land based temps based on GISS, NCDC, Hadcrut or whatever.<br /><br />It will be interesting to see what happens in the next decade.Anonymousnoreply@blogger.com
