different observation data sets.

This involves a combination of satellite

Information is not the same as
data, and we know that
observations and models often represent
different things.
The magnitude it actually had actually risen, how
different these temperatures were from the 1940s, the conflict between model prediction / theory and
observation, etc, were the issues the satellite
data raised.
In the global mean, there isn't much of an issue for the mid-troposphere — the models and
data track each other when you expect they would (the long term trends or after volcanoes, and don't where you expect them not to, such as during La Niña / El Niño events which occur at
different times in models and
observations).
There is a «model» which has a certain sensitivity to 2xCO2 (that is either explicitly set in the formulation or emergent), and
observations to which it can be compared (in various experimental setups) and, if the
data are relevant, models with
different sensitivities can be judged more or less realistic (or explicitly fit to the
data).
Some of them are optimal fingerprint detection studies (estimating the magnitude of fingerprints for
different external forcing factors in
observations, and determining how likely such patterns could have occurred in
observations by chance, and how likely they could be confused with climate response to other influences, using a statistically optimal metric), some of them use simpler methods, such as comparisons between
data and climate model simulations with and without greenhouse gas increases / anthropogenic forcing, and some are even based only on
observations.
As has been noted by others, this is comparing model temperatures after 2020 to an
observation - based temperature in 2015, and of course the latter is lower — partly because it is based on HadCRUT4
data as discussed above, but equally so because of comparing
different points in time.
A series of sensitivity tests show that our detection results are robust to observational
data coverage change, interpolation methods, influence of natural climate variability on
observations, and
different model sampling (see Supplementary Information).
All
different observations of past CO2 levels have their own problems, be it chemical measurements, ice cores, stomata
data or coralline sponges.
The reasons for the differences are not completely clear because each
data set is based on a slightly
different set of
observations, which have been quality controlled, and processed in
different ways.
But
observations suggest otherwise: «We have analyzed
data from
different satellites measuring soil moisture and precipitation all over the globe, with a resolution of 50 to 100 kilometers.
Structural uncertainty is attenuated when convergent results are obtained from a variety of
different models using
different methods, and also when results rely more on direct
observations (
data) rather than on calculations.
If, on the other hand, the differences between station means and station offsets show large variance because
different stations have warmed differently between baseline and
observation intervals, then the last term will greatly increase the estimated
data variance.
-- Brandt et al., 2017 https://www.nature.com/articles/s41559-017-0081 Here we used a passive microwave Earth
observation data set to document two
different trends in land area with woody cover for 1992 — 2011: 36 % of the land area (6,870,000 km2) had an increase in woody cover largely in drylands, and 11 % had a decrease (2,150,000 km2), mostly in humid zones.
The only
observations that would dictate a zero sensitivity would be ones in which temperature was a completely flat line — this would be very
different from their Figure 1
data.
See, the first thing to do is do determine what the temperature trend during the recent thermometer period (1850 — 2011) actually is, and what patterns or trends represent «
data» in those trends (what the earth's temperature / climate really was during this period), and what represents random «noise» (day - to - day, year - to - random changes in the «weather» that do NOT represent «climate change»), and what represents experimental error in the plots (UHI increases in the temperatures, thermometer loss and loss of USSR
data, «metadata» «M» (minus) records getting skipped that inflate winter temperatures, differences in sea records from
different measuring techniques, sea records vice land records, extrapolated land records over hundreds of km, surface temperature errors from lousy stations and lousy maintenance of surface records and stations, false and malicious time - of -
observation bias changes in the information.)
When we look at the distributions (e.g.
data, 1st difference, 2nd difference) of the
observations of global temperature, and of modeled temperature, they are very
different.
If being.1 %
different than
observation is grounds for being declared «physically meaningless», than the law of gravity is in trouble, because recent empirical
data was 2 % off.
For example, changes in time of
observation, adjustment for a move of a station that was previously sited next to a heat source to a better location (that now allows the station to be classed as Class 1 or 2), switch to a
different temperature measurement device or system, etcetera, could explain why smaller classes of raw
data don't track well with the overall trend calculated from homogenized station trend
data.
Not particularly relevant to the rest of the world, where
data quality issues are
different (e.g. poor equipment or maintenance, loss of longer term records through conflict or natural disasters, unreliability of
observation etc).
We can repeat our earlier
observation that CET instrumental to 1659 - this time augmented by the reconstruction using historical records to 1538, demonstrates a temperature profile that looks quite
different to significant periods of the remainder of the Northern Hemisphere if the official version of extended climate - as epitomised by the «Hockey stick» - is taken as the appropriate set of
data which it should be measured against.
In addition to high - quality
data, we need a common
data structure for creating a platform for collaboration that includes
observations and
different kinds of products (e.g. empirical orthogonal functions), both in terms of
data files on disks (e.g. netCDF and the «CF» convention) and in the computer memory.
Then in response to the particular
observation that the balloon
data lie especially far away from the modelers» expectations, the defence is: but we all know the balloon
data is so uncertain and tunable that it can yield lots of
different interpretations, therefore it does not conflict with the hypothesis, so there's no need to doubt the hypothesis of strong CO2 warming.
It is the reason we want multiple repeated
observations of an experiment, prefferably using independant
data sets under
different circumstances.
Together with the CCS
observations discussed above, the contrast with the NPSG coral
data (while not directly comparable in terms of time scale), suggests that despite the fact that baseline δ15N declines are observed in both
data sets,
different biogeochemical mechanisms may underlie the changes in these very
different oceanographic regions.
9Because of the unbalanced nature of the
data being analyzed (i.e., unequal numbers of
observations for the
different levels of the classification variables), the General Linear Models procedure in the Statistical Analysis System was used to perform the analyses.
Through constructing a number of such analogs under
different assumptions as to the structure of inhomogeneities we can begin to ascertain which
data products may be closer to the real world when applied to the real world databank
observations.
Although you can interpret this
data any number of
different ways, here are my top
observations.
