In Response To: Clarity please... (rummer1973)

In the Scientific American article (anyone read it yet?) the models run from 1910 to 2000 with and without human contribution show a 0 degree Celcius predicted change in global ocean temperature without human contribution and predict between an 0.5 and 0.7 degree Celsius change with the human contribution to atmospheric CO2. The actual measured change over that time period is 0.6 degrees.

I haven't read the article lately (but I did just look at the plots). I believe there were eight models, m/l independent, that produced these results.

Regarding changes in solar output, that is addressed in another New Scientist article:

Particularly look at the active links near the end of this article. In the primarly article I quote: Direct measurements of solar output since 1978 show a steady rese and fall over the 11-year sunspot cycle but no upwards or downward trend.
