Hansen 1988: The Sun controls climate

A paper published in Geophysical Research Letters by James Hansen in 1988 shows that Northern hemisphere temperature changes track solar irradiation almost perfectly over the 237 years from 1750 to 1987. Subsequently, Hansen became deranged
Global surface air temperatures: Update through 1987

James Hansen, Sergej Lebedeff

Data from meteorological stations show that surface air temperatures in the 1980s are the warmest in the history of instrumental records. The four warmest years on record are all in the 1980s, with the warmest years in our analysis being 1981 and 1987. The rate of warming between the mid 1960s and the present is higher than that which occurred in the previous period of rapid warming between the 1880s and 1940.

The Hansen climate alarm timeline:

1988: The Sun controls climate
1988: Hansen 99% certain man-made CO2 controls climate
1998: Hansen says "the forces that drive long-term climate change are not known with accuracy sufficient to define future climate change."
1999: Hansen says "Empirical evidence does not lend much support to the notion that climate is headed precipitately toward more extreme heat and drought." Begins data tampering.
2010: Hansen calls for razing cities to the ground, blowing up dams and switching off the greenhouse gas emissions machine
2013: Hansen's mea culpa? Says global warming has slowed due to surge in coal use
2013: Hansen says NOAA is a denier


  1. Can you imagine the homogenization and creativity Dr. James "Thumbs On The Temperature Scale" Hansen could lend to revising sea level data?

  2. This TSI graph...does it actually appear as-is in the Hansen and Lebedeff paper from 1988?

    Or has it been modified for use in this paper:

    1. Graph is from Rahoma & Helal and attributed to Hansen 88, but I don't have a copy of Hansen's 1988 paper to confirm the graph is the same
