Data tampering caused ALL of the global warming reported at the end of the last Century. Here is the proof: GISS Data Tampering – Worse Than You Thought
The graph below shows GISS US temperatures five year mean. At first glance, it looks like the US is really heating up.
Now compare that to the actual GHCN thermometer data which the graph is based on. They look nothing alike. The 1930s were much hotter.
[…] The next graph overlays the published GISS temperature (red) on the thermometer data (blue) normalized to 2003. You can see that they have massively cooled the past relative to the present – to create the appearance of non-existent warming.
Next, let’s compare the actual data to what GISS published in 1999, before they started their most serious tampering: […] Keep reading …
The urban heat island effect shows recent decade’s slight warming near airports. You only have to see the satellite data to see there was little to no warming for decades. Bob Tisdale reports: […]
The period from January 2001 to September 2013 is now 153-months long. Refer to the following graph of running 153-month trends from January 1880 to September 2013, using the HADCRUT4 global temperature anomaly product. The last data point in the graph is the linear trend (in deg C per decade) from January 2001 to the current month. It is basically zero. That, of course, indicates global surface temperatures have not warmed during the most recent 153-month period. Working back in time, the data point immediately before the last one represents the linear trend for the 153-month period of December 2000 to August 2013, and the data point before it shows the trend in deg C per decade for November 2000 to July 2013, and so on.
More adjusting, the IPCC can’t help themselves in pushing the scam along: IPCC Adjusts Model-Predicted Near-Term Warming Downwards
This is another post that illustrates and discusses just how poorly climate models simulate one of the most important climate variables: global surface temperatures. I’ve included a copy of this post in pdf format, linked at the end, for readers who would like to treat this post as a supplement to my ebook Climate Models Fail.
