[...] again in a couple of 2008 posts here here noting (in this case GISS’) inability to locate Canadian station data: How hard can it [...]

At present, I take no view on which of these adjusted versions provides the more correct understanding of temperature in Dawson. However, we do have 3 “adjusted” versions from 3 different sets of experts, which have a range of 3 deg C in their estimates of summer temperature in Dawson, Yukon, a town that has been continuously settled since the late 1890s.

More variations for data mining cannot be a good thing. Such a large difference in data sets has to make tracking down cause less difficult.

This instance also points to why accurate historical local temperatures can be just, if not more, important than the illusive national and global averages on which the data set keepers seem to concentrate.

I believe that widespread availability of Canadian historical climate data is a relatively recent development. That would mean they’ve been sitting in their lazyboys for only ~8 years, not 18.

Vincent and Gullett have published papers about their correction methods and I think their ideas look good. If I had to make a choice, I would prefer their corrected version of any weather station over versions by GISS, GHCN or CRU.

Let’s outsource all GISS and GHCN functions to the Weather Underground at http://weatherunderground.com . Unlike the House of Hanson, they appear to have no difficulty in locating Dawson Canada and providing almost real-time weather updates http://www.wunderground.com/cgi-bin/findweather/getForecast?query=Dawson%2C+Canada .

The Weather Underground has Dawson histories back to June 30, 1996 http://www.wunderground.com/history/airport/CYDA/1996/6/30/DailyHistory.html . The Weather Underground is always very careful to add disclaimers such as “Averages and records for this station are not official NWS values”.

I have two questions for Steve:

1. How accurate is the Weather Underground data?
2. Why are we giving taxpayer monies to bozos when the Underground is making a profit with the data and provides a high quality free service?

so temping, why not?

Will Steve find even more?

To find out, join us for the next episode of Muppet lab, with doctor hansen hunnydew, where the past is being made,…today!

As a Non-Climate-Scientist, it appears that current temperatures aren’t warming but rather historic temperatures are cooling!

That’s one way to create trend lines…
