As for shipping plastic. Pardon me, but do you know the difference
between selling recyclable plastic and flushing it down the rivers?

Interestingly, the market is mostly global and thus the economics are
that it generally goes by ship in some form of containerisation. I
stand to be educated that it is actually clocking up frequent flyer
miles.

Exactly who do you think you're talking to? Yourself? The high and low
temperatures for a day are recorded at National Weather sites. Don't
tell me they vary from your stupid backyard $3 thermometer.

I can see yor problem right there. Your comparative experience and hence
the sum of your knowledge is limited to those. nuff said.
These sites
can be anywhere from hundreds of yards apart to miles to whatever. 60%
of the world wide temperature sites that have US national approval are
in the USA.

So your critizism of these temperature recordings is that they are only
USA centric?


Using recording mercury thermometers means that you have to have a
weatherman there to reset the limits twice a day. There is no
"variation" because the manned national site is the ONLY measurement.

Yep, bananas and dicks have something in common; some of them have
curves, and the point you were trying to make is?



Actually most of the temperatures being quoted are from satellite
readings. NOT local thermometers.

the temperature data from a total of fifteen instruments flying on
different satellites over the years."

The temperature datasets going back to 1880 are entirely ground based national weather stations using mercury thermometers that have automatic setting high and low temperature readings. The Satellite data is only available since 1978 and at this point their records are insufficient to reach any conclusions as to any climate variations. 40 years is FAR too short a time to reflect data on climate.

I'm still waiting on some sort of explanations on how actual datasets on temperatures have "variability".

Well, I was trying to save a bit of space but if you are too lazy to
research it yourself, here goes:

One might ask, Why do the satellite data have to be adjusted at all?
If we had satellite instruments that (1) had rock-stable calibration,
(2) lasted for many decades without any channel failures, and (3) were
carried on satellites whose orbits did not change over time, then the
satellite data could be processed without adjustment. But none of
these things are true. Since 1979 we have had 15 satellites that
lasted various lengths of time, having slightly different calibration
(requiring intercalibration between satellites), some of which drifted
in their calibration, slightly different channel frequencies (and thus
weighting functions), and generally on satellite platforms whose
orbits drift and thus observe at somewhat different local times of day
in different years. All data adjustments required to correct for these
changes involve decisions regarding methodology, and different
methodologies will lead to somewhat different results. This is the
unavoidable situation when dealing with less than perfect data.

After 25 years of producing the UAH datasets, the reasons for
reprocessing are many. For example, years ago we could use certain
AMSU-carrying satellites which minimized the effect of diurnal drift,
which we did not explicitly correct for. That is no longer possible,
and an explicit correction for diurnal drift is now necessary. The
correction for diurnal drift is difficult to do well, and we have been
committed to it being empirically\ufffdbased, partly to provide an
alternative to the RSS satellite dataset which uses a climate model
for the diurnal drift adjustment.

The following plot (Fig. 1) shows the variety of satellites making up
the satellite temperature record and their local solar time of
observation as the satellites pass northbound across the Equator
(ascending node).
Fig. 1. Local ascending node times for all satellites in our archive
carrying MSU or AMSU temperature monitoring instruments. We do not use
NOAA-17, Metop (failed AMSU7), NOAA-16 (excessive calibration drifts),
NOAA-14 after July, 2001 (excessive calibration drift), or NOAA-9
after Feb. 1987 (failed MSU2).

The explanation goes on... and on... and on.. and as you are obviously
too lazy to search and read the original explanation here is the
address. Read it yourself
