Think suns radiation itself is changing causing temperatures to change (cid:1) (cid:1) (cid:1) There is a variation in radiation by sun. There is 11/22 year cycle that shows this change in radiation. 35 years of records that we have seems to indicate that the change in radiance level is only showing an increase in energy of 0. 09w/msquare (cid:1) (cid:1) (cid:1) (cid:1) this is during the period of maximum luminosity. Not significant factor in short term over 100/200 years that we are concerned about and how temp increased so fast (cid:1) Therefore natural mechanism that can change temp but does not explain rapid tempertaure (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) Ocean currents do moderate temperature around the earth. Possible: but plate techs move at mm/ year and we are talking about.
