Outlier stations (another post that is pretty much just for my use)

 Outlier stations are what I call USHCN stations where the data is wildly different from the majority of climate stations.  I don't know why this is, but I don't use them when looking at trends.  It is definitely not always the UHI

Looking at all of the US it is clear that there is a regional climate change, that doesn't seem to fit the Bruckner cycles.  Speaking of, out of all the USHCN stations, only Dale Enterprise shows clear cycles when using Tmin data, which is very cool, and I have found no publications online that mention it.  


I probably have a post about this elsewhere but I don't feel like looking for it right now

Here is an example of an outlier from VA, Lincoln USC00444909   
It does not show the well known cooling starting in the mid 50s, and shows far too much cooling after 1995, compared with other quality stations in the Eastern US
If you are reading this, remember this is the actual data from stations, no alterations of any kind. 

Precipitation data from that station also does not match other stations in the region.














Related stations and climate change (shout out to Michael E. Mann)

Many years ago I read something from 

Michael E. Mann

 about related stations.  He said that station related in space to each other showed the same trends, and you could use stations 500 miles apart to get an idea of how large areas are changing.  My own research confirmed this, especially if you don't use outlier stations, where the data does not match the majority of stations.

The most powerful greenhouse gas is water vapor

 The explosive eruption of the Hunga Tonga-Hunga Ha’apai (HTHH) volcano on 15 January 2022 injected more water vapor into the stratosphere and to higher altitudes than ever observed in the satellite era.

Water vapor is the most important and powerful greenhouse gas.  Increasing the amount in the upper atmosphere, where it does not rapidly cycle out, increases the global temperature.

Very quickly.

The only other large source of water vapor in the stratosphere is from jet aircraft.  Any increase in water vapor over the north pole will cause a drastic increase in temperatures in the arctic.  Because of the cold conditions, flights over the arctic are high in the stratosphere.


Data from satellites shows the greatest warming for our planet is in the arctic.

Climate Central, your source for bad conclusions and limited data

 Climate Central is pushing the narrative that winters are warming the fastest, and all seasons are warming.  This is because the basic global warming theory predicts that is a key signature of global warming.  It is not based on any data.  In reality Spring and Summer show the most signs of warming.  

It's not true for most of the United States.  Climate Central does this by showing you a limited view of the data.

 "The most rapid warming in the U.S. has generally occurred when and where it’s usually the coldest, including at night, in northern parts of the country—and during winter." source

So I check the nearest climate station to that area

Winter is warming the fastest?

How about summer?

I'm not going to bother with the other two seasons, but here is the data





For good measure I randomly picked two other climate stations in North Carolina









No surprise there.  None of the climate stations show anything like what ClimateCentral claims

To compare Raleigh with the climate reference stations
