Estimates of CO2 from natural sources are very crude as evidenced by
the large error factors.

Despite its commonality, one of the
largest factors in reported injuries is user
error.
Including disability status and other
factors, such as accommodation use, in the models may reduce systematic
errors in the value - added for teachers with
large proportions of students with disabilities, but doing so could create incentives for improper placement of students into special education.
It is unsafe to do the calculations comparing the 18th and 19th centuries because the
errors will be much
larger due to the fact that the averages are very close and because the 19th century would be already partially effected by some anthropogenic
factors due to the beginning of the industrialization and some deforestation (that is an anthropogenic component too!!!).
Not only are the TSI and temperature reconstructions very uncertain (hence, probably quite noisy and containing
large errors, as the choice of different curves give such
large variations), but also the fact that the temperature is affected by a multitude of
factors.
Given that you do not (as expressed in your paper) have any characteristics or history of the cycle that would give you a handle on any of these
factors, I submit that within 60 years those
error bars would be
large enough to render your calculated figure almost as meaningless as the IPCC's.
Perhaps this is the source of Dyson's dreadful misjudgment on the climate question: he sees that the possible
errors are
large, but does not
factor in that they are likely to be
large in the wrong direction, and does not credit obvious qualitative arguments from simple laws of physics.»
We also demonstrate that the methodologies used in Scafetta & West [2005, 2006a, b, 2007, 2008] are not robust to these same
factors and that their
error bars are significantly
larger than reported.
There are a
large number of external
factors that can contribute to traffic accidents — it isn't always a matter of driver
error.
