What's lost in a lot of the discussion about human - caused climate change is not that the sum of human activities is leading to some warming of the earth's temperature, but that the observed rate of warming (both at the earth's surface and throughout the lower atmosphere) is considerably less than has been anticipated by
the collection of climate models upon whose projections climate alarm (i.e., justification for strict restrictions on the use of fossil fuels) is built.

a collection of climate models which new science indicates produce too much warming given a rise in atmospheric carbon dioxide levels.

Statistically speaking, instead
of there being a clear inconsistency (i.e., the observed trend value falls outside
of the range which encompasses 95 %
of all
