A nice summary of something the climate models leave out

 Here is a link to a talk by Henrik Svensmark on a mechanism that has an important impact on climate - but is left out of climate models.

Note that at one point in Svensmark's research, his work was debunked by top level scientists who ran large models that suggested his line of approach was worthless. As it turned out, the models left out what was important, and Svensmark's further research found out what it was.

Some messages from all this. First, models are no better than what is built in to them. Second, empirical results that differ from model results imply that the model is wrong. Third, climate is so complex that no models exist that incorporate all the important climate effects. Fourth, the first three messages suggest that climate model results are to be taken with a grain of salt. Fifth, it is naïve (or worse) to think that climate science is "settled". Sixth, government policies based on climate alarmism is likely to needlessly hurt (or kill) people.
