Disputed/Incorrect Graphs
2,000 Years – Incorrect Graph The data in this graph should only extend to 1935, not 1980. Per “Correction to: A 2000-YEAR GLOBAL TEMPERATURE
RECONSTRUCTION BASED ON NON-TREE RING PROXIES” by Craig Loehle, Ph.D. and J. Huston McCulloch, “With the corrected dating, the number of series for which data is available drops from 11 to 8 in 1935, so that subsequent values of the reconstruction would be based on less than half the total number of series, and hence would have greatly decreased accuracy. Accordingly, the corrected estimates only run from 16 AD to 1935 AD, rather than to 1980 as in Loehle (2007). The paper is listed here and a comment addressing the issue can be found here.

For 1,100 years Kirkby 2007, this page presently has:
“Figure 2 http://desmond.imageshack.us/Himg707/scaled.php?server=707&filename=kirkby1.jpg&res=land“
The above does not work because it is missing 3 letters, by having the link as:

What does work is instead adding ing to the end, as follows:

C3 Headlines has a lot of charts at his blog site worth looking into.Maybe you send an e-mail to him about including some of his charts into your Paleoclimate page?
http://www.c3headlines.com/chartsimages.html
I have been wanting this. Kathleen Parker of the Washington Post described the Republicans as “pathetically inarticulate”. We need to get together a good presentation, mainly visual with graphs, that shows the paleoclimate and goes forward to the issues of present temperature and CO2. Most people do not follow the science closely, but really need to know what is happening. I have not heard anyone mention the very important observation that the temperature of our interglacial is decreasing, that each warming, from the Minoan forward, has a lower temperature; this should be alarming.
People who vote need to have a clear, concise knowledge given to them so that they can vote the science and not the hysteria. I’ll look through my stuff and send it.
Thank you
http://services.english-heritage.org.uk/ResearchReportsPdfs/012_2012WEB.pdf Figure 19 gives 9000 years of Central Southern England temperature (and rainfall for 20,000 years in Fig 20)
To quote the report:
“Interestingly, the changes predicted for the 4000-4500BP period by the Bridge CGM are actually quite similar to the predictions of future climate change in the UK (Wilby et al 2006), which implies that we are moving back to a 4000-4500BP climate in the UK”..
May I add a graph, labelled “Past 740 kyrs Dome-Concordia ice core temperature reconstructions”.
It’s buried in Wikipedia and omitted from any reference to where it concerns.

Here is one I found.

Hope it helps.
Good graph and lots of climate info for 2 billion years worth of geologic history at paleogeographer Chris Scotese’s website:
http://www.scotese.com/climate.htm
Scotese refers to todays world as an “Ice house” climate compared to most of geologic history.
Darn that Isthmus of Panama for closing and helping to give us the current ice ages!
This was posted here recently, but here is the original link to

Where the graph was posted a few weeks ago
http://wattsupwiththat.com/2013/01/31/japans-cool-hand-luke-moment-for-surface-temperature/
The beauty of this recent ( 1890-2011) global temperature record is the constant linear slope, no acceleration, no hockey sticks. Same slope before big industrialization/fossile fuel of 0.68C/centuary. Maybe the Japanese global temperature is less adjusted.

I would suggest including Shaviv and Veizer 2003. They provide a graphic that is substantially the same as 545,000,000 year chart offered at C3Headlines. They also argued for a linkage between major climate shifts and cosmic ray flux. Ironically a copy can be found here:

What is the lag time in the reflection of air temperature trend changes in ice cores? How should ice core temperature data be presented when it is used to comment about changes is air temperatures? What constitutes a valid use of ice core temperature data when making public statements about current and future climate conditions?
The only thing that we can conclude from these graphs is that we are experiencing a rapid increase in temperature over a short period of time,
The IPCC 1st Assessment Report Graph should at least be relegated to the disputed graphs sections. There are a number of reason that I can elaborate. Briefly: 1. it was give as just a ‘sketch’. 2. Its sources are poor and invalid – based on Lamb’s estimations for Central England.

Steve McIntyre had a good thread on this graph.

I also reviewed Skeptical Science’s take on the IPCC graph;
http://www.skepticalscience.com/print.php?r=338
and I don’t see any references to Lamb’s “poor and invalid” sources within either thread. Please post links to references supporting your assertions about Lamb’s “poor and invalid” sources.
The top graph on the page does not match its title:
472 Years – CET Extended Graph – Tony Brown – Graph Background
The article linked to under ‘Tony Brown’ on Judith Curry’s blog contains many graphs, this is not one of them.
The graph itself contains an error of attribution. It claims to be based on US meteorology data, but the actual source URL given is to the Australian Bureau of Meteorology. The URL does link to a time series of what appears to be temperature anomaly data. However, the person who produced the chart has obscured the values by seemingly adding a constant to them, perhaps 15. This is nowhere in the source data. The actual data vary in a range of -0.6 to 0.6, and the chart would be more valuable to this page if it was redrawn from the data at the URL.
Looking around on the Australian BOM site, I haven’t been able to find an indication of which anomaly time series this is supposed to be, So the chart, even if redrawn to a proper scale, would be of little value for users of this page.
My suggestion – do not use this chart on this page. Choose one of the charts in the long post referred to in the title, for example

Best of luck!

You are absolutly correct, that was the wrong graph. I was working on several things at once and inadvertantly overwrote the graph on this page with a graph someone had posted in another thread, i.e.:
