A search engine which states answers to questions in statistical form. Here is how wolfram alpha presents Christchurch New Zealand's annual temperature history  ?w=500&h=215 and here is GISS's effort.  GISS Christchurch Homog Feb2011 Chiefio says: Well, GISS certain sees the world a bit differently… One really does have to wonder how they turn cooling into warming. But an adjustment here, and some homogenizing there… it all works out… |

More comparisons between wolfram alpha's temperature data and GISS's here chiefio.wordpress.com/2011/02/18/comparison-temperatures/Good ol' chiefio! He says, "Somehow I think we need a top to bottom end to end brand spanking new global temperature series that has not had all the “usual suspects” monkey with it." |

I went into Wolfram Alpha and randomly entered several cities (these were the first 7 I choose)
Sydney
Madras
Cape Town
New York
San Francisco
London
Moscow
All show temperature rises consistent with global warming.
No doubt WUWT have trawled through the records on Wolfram Alpha to find the few that they think don't fit the global warming pattern.
Yet more dishonest and unscientific nonsense.

I've tried to enter a search into WolframAlpha but haven't got anything like the graphs Chiefio has obtained. Does anyone know how its done?
I entered "average annual temperature 1900 to 2000 Leeds UK". Obviously that was too detailed a demand. I should have simply entered "weather Wherever"

But if you follow the first graph closely (the scaling is much reduced in comparison to the second graph) and ignore the big dip around 1995, then it is seen that the temperature is slowly increasing.
This is evident from examination from 1960 to 1980 where the graph line is approximately evenly spread above and below the red line, whereas after 1980, the graph is tending more and more to be above the red line (again ignoring the1995 dip)
But comparison of graphs using such massively different scales is fraught with eror

I am not suggesting this is a killer refutation of warmist ideology, nay. It's just another interesting source of information.
But these graphs, like many others I have seen for rural areas, seem to show virtual temperature stasis over the last few decades EVEN accounting for UHI.
And, of course, the trend lines are a bit dodgy, too! They depend on start and end points.
As well as being "consistent" with AGW, the Wolfram Alpha graphs are also "consistent" with natural variation and "consistent" with UHI.
Take yer pick!

They may look fairly level but Wolfram Alpha quote the average rise per year (0.087 for Madras and .04 for San Francisco). From my calculations these are both greater than the average rise given by the IPCC (0.7 per century I think). |

But what is the cause? Urban Heat Island Effect, natural variation or CO2 ? Or a bit of everything?
I'm so glad I've discovered this Wolfram Alpha resource. One hopes their data have not been messed around with by climatologists with their ever-upward adjustments.

Looking at Christchurch New Zealand the Wolfram Alpha trend is virtually dead level since 1955 while the GISS temperature shows a rise of about 1.5 degreesC since 1950. What's that all about, nickrr?
You see, the GISS "adjustments" are basically unidirectionally UP.

I've looked at lots of graphs for small towns this afternoon and though Wolfram Grumpfy (joke) shows an upward trend over the longer term, when you look at the period from 1990 very often the slight upward trend has flattened. To me that indicates natural variation rather than CO2-induced warming because as we all know CO2 has been rising inexorably, but temperatures have not.
