As updated in the last post, it turns out NASA’s GISS simply went to an updated version of their supposed temperature record. From this to this. So, naturally, curious people would look to see what the difference is. Well …… let me tell you ….
Now, I’m not going to get into the why’s and why not’s this is legit. I’m simply going to show you what they’ve done, and I’ll let the reader come to their own conclusions. Mind you, GISS has always, always, altered the historical data. It was explained they use an algorithm which causes it. However, this new version of the data appears to have changed for different reasons than their typical historical alterations. (Else, we wouldn’t need a newer version.)
Today’s graphs will show you the differences between the older data set and the newer one. As noted, they stopped the older one in the middle of 2018. Also, because Excel is horrid about dates only in the year format and it hates things before 1900, the first graph ignores data prior to 1901. Let’s look at the differences between their annual data from version 3 to version 4.
Interesting. They actually warmed the distant past to about 1915, cooled the next period to about 1930 or so, and then warmed and then cooled then warmed …… But, do you see what they did to the more recent past? Let’s look at the same graph with a different time period ….
Going backwards in time, starting nearly 40 years ago, our GISS friends time traveled and cooled a couple of decades and then dramatically warmed the last two!
Mind you, the graph isn’t representing temperature anomaly, it is representing what GISS changed from their vs 3 to their vs 4 (of their temp anomalies)! The average alteration for the years 1980 through 2000 was -.0057C. From 2001 through 2018, the average annual alteration was 0.0239C. In other words, simply by changing their version of data, they gave the globe a warming of nearly 0.03C from what they’ve previously stated!
Now, one must wonder what great epiphany GISS had, or what great new revelation they were given to cause them to believe they were entirely wrong about what the global temps were in 2018? Or, 1902, for that matter.
Of course, this is one of the many reasons as to why I remain very skeptical about the claims of the alarmists. That is to say, they are entirely inconsistent with their claims! Recall, ardent warmism started in the 1990s. Now, they say they were wrong about their claims in the 1990s as demonstrated by their altering of their own data! But, now, now, now we’re really super sure and, well, we’re all going to die unless you knuckle-dragging Neanderthals stop driving your SUVs and flying around the countryside! To which a rational person should respond with something like ‘don’t worry, we can just wait another 20 years or so and the data for the current present will start changing as we move to the past’. Who can believe their tripe any longer? It’s nonsense!
