Checking The Climate Scientists

Thanks to NASA’s Goddard Institute for Space Studies (GISS), we can mine the temperature data for the many weather stations across the world.  You know the Anthropogenic Global Warming meme – Human caused CO2 pollution in the atmosphere will cause an acceleration of the Greenhouse Effect and raise surface temperatures on Earth.  I’ve attempted to disprove that theory in an American Thinker article and I won’t go into that again but the purpose of this post is to show everyone how they can look at the station data to see the temperature trends for themselves.

Before you start checking the data, here is the graph that the AGW cult claims to represent global warming which shows that starting around 1978 the global average temperature anomaly increased 0.7°C at a fairly linear, continuous rate. 


Now we can go to this site and point your mouse in the area of the world you’d like to drill into temperature station data.  Once you are on the site, scroll down to the map of the world and it’ll look something like this:


Click on an area and you’ll get a screen similar to this (since I live in South Carolina, I selected a point in the middle of this state):


This page gives you data such as the distance from your mouse click, the city name, population (important due to urban heat island effect), and the range of years covered in the data.  You need to choose sites that have data that span a long range and is current (at least past 2010) to get a view of what the temperature station has recorded over a large sample size.  For example, don’t choose one that ends in 1970 like the Sumter/Shaw AFB station in the previous example. 

Let’s click on a few in the South Carolina area and see if those stations match the global temperature Hockey Stick that the AGW cult presents.

The graph from Augusta, Ga:

 From Winnsboro, SC:

From Columbia, SC (For those in South Carolina, this is the largest city and should show hotter temps due to urban heat island):

 And for the NASCAR fans, here is Darlington, SC:

These graphs don’t show a lot of warming as compared to the global graphs so is South Carolina charmed and immune to this CO2 scourge?

Let’s check California because they have adopted CO2 reduction laws so they must be seeing the warming.

Here is the graph for Wasco, CA:

 Here is Pasadena, CA which has a population of 14.5 million people:

But here is Los Angeles, CA which also has a high population:

Here is a sparsly populated region (<10,000) called Tejon Rancho:

Well, apart from Pasadena, it appears California doesn’t show the warming either.  Maybe we are looking in the wrong area.  I keep hearing about polar ice melt so let’s check out Greenland.

Here is a station from Angmagssalik and it does show the warming.

But here is one from Godthad Nuuk that doesn’t match the above temperature trend and this station is roughly the same distance from my mouse click as the Angmagssalik station.


Let’s try another northern latitude area such as the upper portion of Alaska.

Barrow shows the warming here:

 But just 400km south of Barrow, in Kotzebue, Ral we don’t see it.

 Remember that GISS has openly stated they use “smoothing radii” to calculate the global temperatures that are shown on graphs and maps (this method is described on the GISS page here).  This smoothing radius technique means that the temperature data for a single weather station will now represent the temperature data for a large area that is contained within a circle centered on the weather station and having a radius of 1,200 km.  Crazy, isn’t it?  Yet, as I showed above, stations that are much closer than 1,200 km exhibit very different temperature trends and this smoothing radius trick has already been thoroughly debunked here

So you see the contradiction we have with the AGW conclusions and the raw weather station data.  The AGW cult continues to show global temps increasing but when you mine the individual weather station data you don’t see the overwhelming warming trend. 

But then again, the AGW scientists are prone to tricks.

    You’re so interesting! I don’tthink I’ve
    read through something like that before. So great to discover somebody with a few genuine thoughts on
    this topic. Really.. thanks for starting this up. This website is one thing that is needed on the internet, someone with a little originality!

  4. Hello very cool site!! Man .. Excellent .. Wonderful ..
    I’ll bookmark your site and take the feeds additionally?
