The ignorance of science and the willful attempt to mislead is strong here.

1988: The Sun controls climate
The paper indicates climate tracks the solar output for a period through 1987, but it diverges after this paper is written.
Quote:
1988: Hansen 99% certain man-made CO2 controls climate
It appears the unreferenced statement was that human emissions of CO2 was changing the climate which is different from saying it alone "controls" climate, as implied.
Quote:
1998: Hansen says "the forces that drive long-term climate change are not
known with accuracy sufficient to define future climate change."
The difference between a long term climate driver and a shorter term driver is significant. Given there is no context for the timeframe being discussed, there is not a lot which can accurately be taken from the quote. However, if one reads the following sentences there is a better understanding.
http://www.pnas.org/content/95/22/12753.long Anthropogenic greenhouse gases (GHGs), which are well measured, cause a strong positive (warming) forcing. But other, poorly measured, anthropogenic forcings, especially changes of atmospheric aerosols, clouds, and land-use patterns, cause a negative forcing that tends to offset greenhouse warming. One consequence of this partial balance is that the natural forcing due to solar irradiance changes may play a larger role in long-term climate change than inferred from comparison with GHGs alone.Quote:
