GloBull Warming Hokum On ‘Earth Day’ by Karl Denninger

Karl Denninger takes on the global warmists. From Denninger on a guest post at

Let’s cut the crap, shall we?

This is scientific fact. It is a record of history showing temperatures and CO2 levels.  You will note that there is no correlation between temperature and CO2 level.  In fact, there appears to be an inverse correlation in many (but not all) instances.

I remind you that the basic truth of science when it comes to correlation and causation is as follows:

1. Correlation can never prove causation.  It can only suggest that it might be true.

2. The inverse of correlation, however, strongly indicates that causation is absent if it occurs just once.

Well, it has been inverted when we’re talking about CO2 and temperature — and far more often than once.

In the Precambrian era CO2 concentrations fell quite a bit while temperatures rose.  In the Silurian period, same.  In the Carboniferous period, again.  At the end of the Jurasic period, again temperatures went up while CO2 levels fell.  Finally, at the exit of the Jurasic period CO2 went up while temperature slowly fell; we believe that happened due to a large asteroid impact (which would make sense as to the step function) but the continued fall in temperatures does not correlate with a further rise in CO2 — until the exit of the Paleocene epoch.

There was a correlated rise in the Miocene epoch.  But then we saw changes in temperature — both up and down — with a nearly-constant CO2 concentration.

Is there scientific evidence that CO2 levels cause global temperature change?  No.  The science says otherwise absent specific and detailed means of disproving why that correlation has been so-often not only absent but inverted.
