Another trick from the hockey stick team

Well this is a new one...for me anyway.  A graph that uses a tricky quasi-log scale on the X-axis to minimise 1000's of years of warmer Holocene temperatures, to make today's temperature seem scary and warm:

 

 The poster of this graph on Twitter says it's a "usual graph":

 

@EcoSenseNow @royalsociety Unusual graph, where did you find it? More usual to see something like this: pic.twitter.com/LK0A6BBB26

Well it's not the usual graph I've seen. Here's what I call a more normal depiction of Holocene temps:

And another:

 

 

From: http://www.resilience.org/stories/2010-05-17/lessons-climate-history-implications-post-carbon-agriculture

 

So let's look at the problems with the graph at the top.  First of all the higher Holocene temps have been really minimised; the "Vikings in Greenland" time span is depicted as 0.4C above the 1940's temperature and about as warm as today. This, despite the fact that today Greenland is not as warm as it was when Vikings successfully colonised Greenland.

 

Second, the period between 10,000 years ago and 2,000 years ago is compressed by the "quasi-log" scale (yeah, real "quasi") to appear only about 100 years long.  But now check this: even though that 8,000 years is compressed to be such a short period of time, the spike in temperature just before the Younger Dryas appears to be in the same horizontal scale as the uncompressed right side of the graph. If it was a consistent X-axis scale that spike would be a microscopically thin finger.

 

So, when they want to minimise times on the X-axis to suit the global warming narrative e.g. from 10,000 years ago to 2,000 years ago, they do it.  But when they want to emphasise features and extend the scale on the X-axis, they do it, whether it's on the right or the left of the graph. Wow, that really is a "quasi" log scale. In other words they put whatever they like in this graph and the low-information believers of AGW will not know any better.  More sheer deception from the hockey stick team.

 

Another problem is pointed out by Nospin_43:

 

@CarbonFooledYa @tan123 scale for 21st century easily allows it to show the 17 yrs flatline but no completely ignored.

I found this graph in this pamphlet, but I'm not sure if that's the original source or not:

Finally, the projection on the right of the graph is the usual pie-in-the-sky one from the IPCC. Such fraudulence, typical of the AGW movement.

Update: I've been blocked by @Toby_Bruce as result of this single tweet reply I made to his tweet, shown at top of this post:

@Toby_Bruce @EcoSenseNow Usual? They use quasi-log scale to compress 8,000yrs (10K-2K yrs ago) of warmer Holocene temps to look like 100 yrs

I get this time and again from warmists on Twitter. A single critical tweet of their precious AGW world view and I must be suppressed. Meanwhile higher profile skeptic tweeters such as @tan123 and @EcoSenseNow don't get blocked. Why are AGW believers so intolerant of different points of view?!  It seems like a fascist tendency.
