:"...What does it say that the modeling that guaranteed disastrous increases in global temperatures never predicted the halt in planetary warming since the late 1990s? (MIT's Richard Lindzen says that "there has been no warming since 1997 and no statistically significant warming since 1995.") What does it say that the modelers have only just now discovered how sunspots make the Earth warmer?
I don't know what it tells you, but it tells me that maybe we should study a bit more before we spend billions to "solve" a problem we don't understand so well."
