In reply to Steven Miller. I also noticed the charts that didn't have biased/adjusted ground station data conveniently start at the end of 1970's cold period. Those Globull Warming Alarmists are tricky folks.

In reply to JeffT. Any time I see historical records that show the 1930s as cooler than today... I am skeptical. EPA “Disappears” the 1930s Drought and Heat Wave Climate Data – Watts Up With That?

In reply to Mike Mellor. WHERE CAN ONE GET ABSOLUTE TEMPERATURE? I once saw a chart of absolute temperature from the 1800s to present, but I cannot find it now. Can any one provide the link?

In reply to Wm Yeager. Many weather stations have been relocated as well. A relatively minor move can be enough to substantially change the readings. From coastal to a couple of miles inland for instance or a change of altitude of a couple of hundred feet. Has anyone looked into any adjustment of weather station readings to acknowledge these alterations?

In reply to TheFinalNail. That's a bit weird looking at it that way. The data looks like there was a plateau at about -0.2C (anomaly) from 1980 to 1998's El Nino which left temperatures at 0.0C from 2000 to 2015, another El Nino and then a new level at 0.2C.

A plot of a non-anomaly GAST would be nice — showing the nearly straight and level plain of 14.7 C air temperatures since 1880 or so.

In reply to George. Mods: no luck with the updates yet? It's over a year since the above comment was made and the UAH chart still stops in Feb 2018. The RSS TLT chart appears to stop in early 2017 and is still showing the discontinued v3 data. RSS TLT v4 has been in use since July 2017 - almost 3 years now. Have these updates been abandoned by WUWT? Thanks.

In reply to Bill Everett.

The linear warming trend in UAH from Jan 2005 to May 2020 is +0.25 C/dec. That’s considerably faster than the warming trend in UAH from Dec 1978 to Dec 2004 (+0.15 C/dec).

https://woodfortrees.org/graph/uah6/to:2005/plot/uah6/to:2005/trend/plot/uah6/from:2005/plot/uah6/from:2005/trend

If we edit out the warming signal caused by El Nino but retain the cooling signal caused by La Nina then should we be surprised that overall the warming trend reduces?

On the UAH satellite map if a straight line is drawn from the temperature for 1979 and extended through the temperature for 2004 and another line is drawn horizontally from the temperature for 2004 forward in time the presence of changeover from continuous warming to pause in warming is obvious. Since 2004 most of the temperature readings for the succeeding years fall below the horizontal line. This is more obvious when the temperatures for the major El Ninos of 1998 and 2016 are deleted.

I am wondering where geographically the apparent warming in the past 20 years is occurring. I have seen some maps that show almost all of the delta above 20th century average temps, isolated to regions within and near the former USSR. Do you have some reliable maps showing, say, each decade’s temperature delta spatial distribution across the planet? Would be interesting to see if the same temperature reporting stations keep reporting anomalies each decade, or if the deviations are more well-distributed worldwide.

The very globality of the “global” temperature hasn’t been addressed enough, and that should come before everything else, before the trends, before the models and before predictions. How do we know the global sampling was adequate for the entire industrial period when even as of 2013 it wasn’t adequate for one of the main datasets, the HadCRUT4: https://rmets.onlinelibrary.wiley.com/doi/full/10.1002/qj.2297? HadCRUT4 covers 84% of the globe, with the worst coverage in Africa and on the poles. I seriously doubt the globality of pre-war measurements, and even after the war they are suspicious. How do they account for the missing data?

We are taking the mean temperature values for granted in these graphs, on both sides of the debate, but we really shouldn’t.

Also, if we do, HadCRUT4 shows a big pause in the temperature rise between 1940 and 1980. Are we supposed to believe that everybody went green in the most intensive period of the post-war rebuild?

The RSS TLT chart (3rd chart from the top) shows the old version 3 data, trend 0.134 K/dec. Updates stopped being added to version 3 some time ago (although the horizontal axis on the chart above suggests otherwise, for some reason). RSS TLT version 4, trend 0.204 K/dec, is the producer’s latest and fully updated operational data set:

The UAH global temperature chart on this page was being updated monthly through February 2019. Since then it has not been updated – as temperatures have moved upward. “Watts up with that”?

[Nothing sinister. From that page: “all of the data is linked from third party sources and WUWT is simply an aggregator.” We will look into why its not linking. Mod]

I have just found some time to read through all the threads. I love both the way so mch factual data is presented as well as the clear scientific rebuffals to the odd alarmist popping up. Keep up the good work

With the increase in competition and product supply within these
industries, as well as tax incentives and possible government subsidies of those clean energy resources, cleaner smarter energy have been around in reach of numerous quickly another several years.

We are currently investigating some areas for average investors and funding your company
too take advantage of some BIG lucrative opportunities later on because they areas grow and develop on the coming years.

subsequently, connects to the motor.

In reply to Bruce Atwood. Bruce, the disconnect still remains for previous datasets throughout earth's history on CO2. However, Cosmic Ray Flux vs Temperature is still spot on.

The UHA temperature graphs have not updated here since September. They show a decisive downturn in temperature now 12/30.

In reply to Mark L Gilbert. Can you give me the link? And who took the data? Is it the same one that is taking data of the oceans' temperature in current days? I get that some scientists can approximate the temperature, but at this point? And why would a scientist be more credible than another one? Thank you in advance.
