This seems major to me....

Thanx !

 

Beam me to Planet Gore !

Interesting. Yup, how do you get three significant digits for “global temperature”, especially prior to 1945?

In my world, everything has error bars, even when I count upsets in an SRAM.

To make the long story short, it turned out that no one had ever surveyed the temperature sensors of climate stations to see whether the assumption of uniformly iid measurement errors could be empirically validated

interesting..thanks

There is further error measurement by Jane Warne of BOM at Broadmeadows, N of Melbourne

There is a quite fundamental question which I have never seen addressed. In the reconciliation with temperatures over the land or sea surface, should on measure 1 mm, 1 cm, 1 m, 1 km or 10 km above the surce, or at some intermediate value determined by experiment?

If the experiment has been done, what was its purpose and how was it established as the “right” altitude?

It seems that we are adopting initial conditions for complicated model projections like GCMs based on the convenience of being able to read a thermometer at about eye level.

Is that a scientific approach?

I don’t even know where to stick the thermometer.

All these things must be given to those that potentially can control the outcome of this administration's hell bent mission to cripple the United States Economy and future industrial complex even more so then they already are doing.
Namely. Members of the US HR and Senate who are willing to have their staffs carefully absorb all that is becoming available. And hopefully the outpourings of concerned and now better educated people in all western nations will do likewise. Their very existence as free peoples that have a few bucks in their pockets are just as much stake as American's wallets are.

Stick a thermometer in Massachusetts.

OMG! My Grant Money Likelyhood Indicator has flatlined!

Frowning takes 68 muscles.
Smiling takes 6.
Pulling this trigger takes 2.
I'm lazy.

The assumption was that all the instrumental error was random, independent, identically distributed (iid) error.

And to think the U.S. already blew over $80 billion on this precautionary hypothesis, and they want to hamstring this lame economy further with expensive energy. By these standards, Jared Loughner is probably sane.

Wow, those 120 year old sensors must have been built well. ;') Thanks Ernest!
