The reason there's «much traffic for woodfortrees» is that it's by far the best online tool for looking at GISTEMP etc. from a great variety of perspectives.

Following an email to Hansen and Ruedy of GISS, they changed the introduction at the GISTEMP intro from: to the following:

The models overestimated warming from 1979 - 2011, but if you look at GISTEMP for example you can see that the East Pacific is cooler in 2011 than it was in 1979 and the models did not capture that as they have no PDO in the correct phase and are not expected to because PDOs are transient changes.

John Cook, Here is the 2006 paper, and here is the updated graph, which you can find at gistemp bottom of the page.

For an example of how that «citizen science» can really work, look at what Ron Broberg and Zeke Hausfeather are doing with the weather station data — they aren't sitting around declaring that «it can't be done» or that the GISTEMP / CRU / NCDC methods are fixed, they are going into the data, making choices, seeing what impact they have and determining what is robust.

In particular, the characters visit Punta Arenas (at the tip of South America), where (very pleasingly to my host institution) they have the GISTEMP station record posted on the wall which shows a long - term cooling trend (although slight warming since the 1970's).

Posts at RealClimate (here) and at SkepticalScience (here) looked on the paper as the second coming of... errr... Hansen's GISTEMP maybe, saying Cowtan and Way (2013) proved the UKMO HADCRUT4 data underreports by half the warming of global surface temperatures since 1997.

The tool / website will promote the goals of the Climate Code Foundation by providing an intuitive and informative interface exposing the GISTEMP data at a level comprehensible and usable for anyone from lay persons with a vague interest in climate change to climate scientists.

However, the impact of coverage bias is pretty clear; it can be seen by simply looking at a coverage and anomaly map as we did here, or by assessment of coverage bias using GISTEMP, or by the less valid but independent assessment using UAH.

This can also be seen in the final figure from Morice et al 2012 (detail here), in which HadCRUT4 is at the top of the pack over recent years, although GISTEMP and NCDC both lie within the uncertainty range.

Using GISTemp Land / Ocean Index values and Niño 3.4 values, I computed 12 - month running averages of Niño 3.4 and compared them to the average GISTemp values at lags of 0, 3, and 6 months.

«Obviously the GISTEMP [Goddard Institute for Space Studies Temperature] analysis is independent of that and records or trends in its index stand alone,» Schmidt told The New American at the time, though most of the establishment media seemingly never got the memo or bothered to ask the question.

Now let's look more closely at the difference between the non-interpolated data sets (HadCRUT4 and NOAA GlobalTemp) and their interpolated counterparts (Cowtan & Way and NASA GISTEMP respectively).

Running 60 - month averages of European air temperature at a height of two metres over land (left - hand axis) according to different datasets: ERA - Interim (Copernicus Climate Change Service, ECMWF); GISTEMP (NASA); HadCRUT4 (Met Office Hadley Centre), NOAAGlobalTemp (NOAA); and JRA - 55 (JMA).

Running 60 - month averages of global air temperature at a height of two metres (left - hand axis) and estimated change from the beginning of the industrial era (right - hand axis) according to different datasets: ERA - Interim (Copernicus Climate Change Service, ECMWF); GISTEMP (NASA); HadCRUT4 (Met Office Hadley Centre), NOAAGlobalTemp (NOAA); and JRA - 55 (JMA).

Unfortunately the GISTEMP site's mapping capability is down at the moment, otherwise I would show you.

All that is at issue here is that UAH saw the 1998 El Nino signal more clearly than GISTEMP.

GISTemp recently started using satellite observations of lights at night to identify urban regions — more light means more urban.

And if you look at zonal temperature records (ie GISTemp below), the place with the big temperature during the early 20th century was the high northern latutudes that do conveniently have ample ice to melt.

'' Zeke Hausfather says: August 12, 2010 at 2:27 pm Contrary to popular conception, the - only - adjustments GISTemp makes to individual land station records are to correct for UHI.

You find them at exactly the same locations in GISTEMP, HadCRUT3, and NCDC temperature curves.

By the way, I am talking of actual temperature measurements here and am excluding the sharp peak in GISTEMP at the beginning of 1998 which gives it a boost of 0.07 degrees.

Back at the original post, I've applied reduced chi - square to see if a ramp plus plateau fits the GISTEMP data beginning in 1979 better than a ramp alone and that appears to be so.

I think we can all agree that in at least this case the GIStemp algorithms failed.

1998 in GISTemp shows what is supposed to be seen in the difference between surface temperature and the altitude that satellites measure temperature at during El Nino.

Figure 8 — 1 from National Aeronautics and Space Administration (NASA), Goddard Institute for Space Studies (GISS), «Global Land - Ocean Temperature Index in 0.01 Degrees Celsius,» at data.giss.nasa.gov / gistemp / tabledata / GLB.

Let's look at the last 40 years from GISTEMP.

Bob Tisdale says: August 20, 2010 at 2:04 am Steven: Isn't 2005 the current record high year for GISTEMP?

For HadCRUT, CRUTEMP and NCDC, these changes are significant at better than the 95 % CL, and for GISTEMP and HadCRUT + C&W, they are better than the 90 % CL.

So pointing at the «now» version of GIStemp is just saying the walnut shell moved, and we'd all better keep an eye on it or we won't find the pea.

GISTEMP calculates them at grid points, as I said in my previous post.

GISTEMP gives you a way of looking at the gridded data graphically, and it looks like Illinois has significant warming over the century from that too (0.5 - 1 C in this example).

Not that we think the Goddard Institute for Space Studies team are particularly good at establishing global temperature or anomalies, at least no better than other industrious teams attempting to do the same thing, it's just that GISS's GISTEMP is consistently delivering the warmest anomalies and accelerating away from the pack (well it is the house of Hansen, so - called «father of global warming»...).

At first I thought I could use the v2.inv file supplied by GISTEMP, but the GHCN station identifiers for the contiguous US have changed (so that they're based on their USHCN station identifiers — probably a good thing).

At the same time the GISTemp global temperatures must be in excess of 0.17 C greater than today (to get another 2.2 C by 2100).

The full 2015 surface temperature data set and the complete methodology used to make the temperature calculation are available at data.giss.nasa.gov / gistemp /.

Having a quick look at it, a good starting point would be to compare the CO2 - rise with, say, GISTEMP, as the SAT records have similar characteristics to the CO2 - rise data from MLO.

And NOAA has posted for March with a global anomaly of +0.83 ºC, showing a bit more of a bounce back up than seen in the March GISTEMP / TLT anomalies, in NOAA up from +0.68 ºC in February while January sat at +0.70 ºC.

GISTEMP has posted for March with a TLT global anomaly of +0.89 ºC, showing the same tiddly bounce back up seen in the March TLT anomalies, in GISTEMP up from +0.79 ºC in February while January sat at +0.77 ºC.

Scenario B is at +1.035 C for 2010 while GISTemp in a high cycle El Nino - impacted year is going to be a little over +0.600 C (which is still lower than Scenario C (+0.632) which stopped CO2 increases in the year 2000 at 367 ppm — while we are already up to 388 ppm.

Returning to the comparison of UAH TLT anomalies and GISTEMP LOTI, I've widened the range of the contours to help show the differences at high latitudes in the Northern Hemisphere.

As per GISTEMP and due to the low number of stations, I used a 1000 km radius for averaging the grid temperatures (with the weight of each station declining to 0 at 1000 km).

So in example A, removing stations at northern latitudes, this won't make GISTEMP warmer.

Converting the anomalies to the actuals, GIStemp in 2002 had Global Mean temperature in 1880 at 13.89 oC, and by March 2010 this had fallen to 13.76 oC, i.e. colder, not warmer, as your comment claims, thereby exaggerating the apparent warming since 1880.
