Re 15
See http://nsidc.com/news/press/2007_seaiceminimum/images/20070910_extent.png On further reflection, if the melt in the late ’30s looked like now, there is neither reason or likelihood that any sailors would have sailed into that huge bay that has melted, and less probability that aircraft would have overflown more than a skmall part of it. It is close to a dead certainty that, under such conditions, the ice extent would have been substantially overestimated in the years near to and including 1940. Murray

RE: 20 Thanks. Makes me feel silly
Re: 21 Thanks, but I don’t find a “CSV option” and don’t get any choices beyond monthly (no annual data?), and get no data when I choose monthly and the CD is only to 2002. Are there no plots showing yearly averages roughly 1930 to 2007? Murray

Re: #15

Murray, You can get up to date Canadian data from Environment Canada.

http://www.climate.weatheroffice.ec.gc.ca/climateData/canada_e.html

Pick your location and look for the csv option at the bottom of the page to get the data for use in excel, etc.
You can also download a CD with daily data for all of Canada up to 2002.
I’ve been looking closely at the data for Calgary (where I live) which dates back to 1885. The warming trend evident in the annual data is almost entirely due to warmer winters (January and February). All other months show pretty constant temperatures.

I am not sure what that means (as I am not even sure I would qualify as a jester)…, but looking only at annual data does not tell the whole story.

Tried to send a longish partially off topic message, about 1 and 1/2 pages in Word, but it seems to have not been accepted. Too long?? Too much off topic?? Other??
Note, whenever I post my little green bars stall at about 1/2 way, no matter how long I wait. If I hit “submit” a second time I get a message that I have sent a duplicate, but only the one seems to post. This time, after more than 1 hour I hit submit again, got the message and it seems it still didn’t post. Any suggestions? Murray

That GISS or CRU “cool the past” to up the trends is nothing new. Just visually compare IPCC 2001 to IPCC 2007 global temperature graphics and the differences jump to the eyes.
Such a large scale data tampering game can continue forever as long as there is backing from the politics.

Climate change science in action: it seems that within the past few days,
Detroit Lakes, Danevang, and Boulder, all got cooler about one hundred
years ago. That should help the trends.

Steve, it may be time for you to do another one of your “scrapes” of GISS data.

Also, if you can generate a GHCN format file from your previous scrape, it may
be of use as a comparand for Not Sure and the others who are working at emulating
the GISS processes. Comparing to what is currently online at GISS will result
in false negatives.
