In order to understand the potential importance
of the effect, let's look at what it could do to our understanding
of climate: 1) It will have zero effect on the global
climate models, because a) the constraints on these models are derived from other sources b) the effect is known and there are methods for dealing the errors they introduce c) the effect they introduce is local, not global, so they can not be responsible for the signal / trend we see, but would at most introduce noise into that signal 2) It will not alter the conclusion that the
climate is
changing or even the degree to which it is
changing because
of c) above and because that conclusion is supported by multiple additional lines
of evidence, all
of which are consistent
with the trends shown in the land stations.

of consistency
with other types
of evidence, the extent to which known uncertainties are accounted for in and between studies, and whether there might be other physically plausible explanations for the given
climate change.

Nonsense, since systems science — public health or

of old ones.

change climate sensitivity much).
Can you not see that it is one thing to attribute a cyclone to

of evidence and analysis supporting the mainstream position on
climate change are diverse and robust — embracing a huge body

with greenhouse gases, insights derived from the reconstruction
of causes and consequences
