VS has only looked at
the GISS temp record as a time series (in looking back he also did some preliminary work on the other temp series), and has not attempted to relate this anything else, lagged or otherwise.
The recent admission by NASA that
the GISS temp since 2000 was in error, and the restoration of 1934 as the warmest year in the last century certainly does not come from your curve.
And, it's been a rough old winter for Gavin Schmidt's NASA
GISS Temp New York office — home of the «Hottest Year (s) Evah» sausage factory — with the city that never sleeps experiencing its «fifth consecutive season that at least 30 inches of snow has fallen» with CNN reporting «It's official: NYC hasn't seen snow like this in 130 years ``!
The temperature divergence, this century, between NASA
GISS temp (land based) and RSS satellite data, is mind - blowing.
There is a growing divergence between NASA's (land - based)
GISS temp and RSS (lower troposphere) satellite temps since 2000:
I highly recommend visiting Tony Heller's site «Real Climate Science» for a comprehensive understanding of the blatant manipulation of NASA's
GISS temp data set to fit the global warming narrative.
So what other use is looking at
GISS temp?
As
GISS temp numbers always change in later issues it is safe to admit that they are wrong (and ignore them).
I look at the exercise at looking at
GISS temp numbers from the perspective of recording historically how these are, and how these will change.
Figure 2: Pacific Decadal Oscillation index (blue, University of Washington) versus Global Temperature Anomaly (Red -
GISS Temp).
That is the Tasmania and Southern South american reconstructions with
GISS temp for that latitude, You have a little hockey stick action but look at the average, in estimate Wm - 2 for that chart.
And as a side point, what really spurred me to dig deeper with an open mind, was when my «heroes» from the sceptical stance did their own analysis of
the GISS temp records and found that they were sound.
I suggest you download
the GISS Temp data and see for yourself how noisy the data are.
- He gets tons of press (way more than NOAA)-- He put GISS on the map (if it wasn't for Hansen and his stunts no one would care about
the GISS temps)-- He gets tons of funding for his dept. (will say and do anything for more press and funding)-- He gives all his fellow dept. workers job security — He has no Ethics (good for government work)-- Face it He is the King of the Scientificness «Grant Whores»
Bart: do you have data for the aerosol components of net forcing at the actual locations where
GISS temps are measured before being gridded and amalgamated?
Not exact matches
A question: I have a vague memory of years ago someone «denier / pseudo stats dude» was hassling nasa /
giss for their raw data of what they used to feed in the avg / mean models for global
temps... saying that the adjustments being made was being done to over-state the extent of warming?
I just looked it up and it has SH land
temps for Sep 08 as +0.44 C or 10th warmest, well below Sep 05 at +0.85 C. (Of course, it has very limited Antarctic coverage, but then again I don't know how many more stations
GISS takes into account.)
I think Rasmus points out that model simulations where the available
temp data is plugged into the models (i.e., the re-analysis) provide support for a warming Artic and
GISS's interpolation / extrapolation method.
Why is the
GISS data so out of phase with UAH, RSS, even HADCRUT all showing
temps falling in Q4 2010 while
GISS shows a sharp rise?
This would certainly explain why arctic sea ice cover has been absolutely crashing in recent years while the HARDCRU /
GISS global average
temps had been increasing more modestly.
GISS year - to - date would be but 9th among the annual
temp list, and NCDC would be but 6th.
NASA
GISS does not show Northern Hemisphere
temp anomaly, but does so for the Southern Hemisphere: +0.30 C. Global being +0.68 this means that Northern Hemisphere was about +1.1, three months in a row above 1 degree, tri-fecta only repeated twice Jan - Mar 2002 and Feb - Apr 2000.
If there is indeed a fairly close correlation between the US surface
temps and US satellite
temps, then that would show just how «whacked out» the
GISS and Hadcrut
temps could be.
I think this could be a significant way of looking at how accurate the Satellite data is, compared to respective US
temps, and then
GISS and Hudcrut Global
temps.
I've updated the graph at top to show a comparison with
GISS ocean
temps, click to refresh if it doesn't show up as a two - panel graph.
Where at the closest operational rural
GISS met station to Madrid (up on the sierra at Navacerrada) the mean
temp was 6.7 C in October.
Chris V. CO2 goes up,
temp goes down, oceans cool, sea levels decrease, arctic sea ice is within 1979 -2000 mean, AGW theory of catastrophic warming is B U S T... Even the fraudulent manipulation of the
GISS data set does not change that.
«you probably noticed the mcintyre et al depiction of
GISS annual
temp estimates for US over time.
What is also interesting is that the US surface
temps are way below «average» this year, yet on the
GISS maps, they aren't being reported to the same degree of cooling as what NOAA is reporting.

I would point to TSI, OHC, sea level, humidity,
temps, Sea Ice, nothing is good enough for either side except the highly adjusted surface
temps from
GISS and not even they fully support the models and appear to conflict with other measurements!!
I should add that while
GISS opine that in 99.9 % of cases anomalies will be an adequate simplification, if you want, as here, to compare absolute model
temps to actuals you are in the 0.1 %.

Well, go look at http://kenskingdom.wordpress.com/ to see how
GISS has «modified» the
temp data in Oz according to the site.

Does anyone have
temp datasets from FMI to compare with the
GISS data?
The issue is the time of the year, latitude and type.The Krakatoa problem is well known eg Stenchikov 2006 ie that the models over estimate the global forcing.Hansen suggested that the observations were incorrect, however the
Giss model gets the AO sign incorrect and arctic central
temps incorrect in scale and time so.This is due to the incorrect heteregenous chemistry at high latitudes eg chapter3 WMO 2003, Ozone assessment 2011.
You also don't deal with that fact that UAH has changed the way they calculate global
temps in the past few months to make 2010 look cooler while
GISS has been running the same algorithms for some time.
NASA's «
GISS»
temp uses land and ocean - based thermometers which measure «different parts of the system [UHI affected parking lots, asphalt heat sinks, AC exhaust air vents], different signal to noise ratio [we bias toward warm stations], different structural uncertainty [we «homogenise» our data set to cool the past and warm the present to fit the global warming narrative].»
It shows a
GISS global
temp map for April 1978, and a purported corresponding map for April 2008, to show how coverage has shrunk.
I thought the entire error range for NCDC global surface
temps was 0.09 C + \ - 0.045 C. (NASA
GISS is + \ - 0.05 C.) But the error bars on the graph in this post show + \ - 0.09 C which is 0.18 C overall range.
In «Spinning the Warmest Year» I issued a challenge for anyone to re-graph either the HadCrut4 or
GISS global
temp dataset without 1998.

I reckon ALL the sea and land
temp data from
GISS, Hadcrut, NDCD, NOAA and the arctic ice data from cryosphere and NCDC has been manipulated to suit the AGW agenda.
This is trivial, there are flat
temp times in
GISS and HadCRUT, this remark is below quality... 4.
GISS adjustments result in a lower centennial
temp trend than raw for global surface stations, and lower for the last 50 and 30 years than raw.
One more question; in your

But when
temps stopped rising after 1998, this type of filter misbehaves and they conveniently changed the type of padding used in the
GISS smoothed graphs and others (and IPCC).
