Yet Another Amazing Detail About Climate Science

They’ve got incredible supercomputers to play with, but still our climate scientists build up global anomaly charts from only a handful of stations (1,000 or so if the guys at Climate Monitor are not mistaken, or one on average for every area the size of Bangladesh).

You’d think world-rescuing climate specialists would have computers and bandwidth enough to handle data from a million stations by now, or a billion even. But they say they don’t even need that.

Why not? Because they have discovered that 1,200-km grids are ok. Why are they ok? Because

temperature anomaly patterns tend to be large scale

How so? Here’s the root of it all, from 1987:

The 1200-km limit is the distance at which the average correlatiom coefficient of temperature variations falls to 0.5 at middle and high latitudes and 0.33 at low latitude

Who would believe that it all depends on a correlation coefficient of…0.5?

My Podcast At “365 Days of Astronomy” – Moon Colonies

My first ever podcast, entitled “Moon Colonies”, is now available at “365 Days of Astronomy” for January 23, 2011. The 10-min MP3 audio recording is at this link (including the shortest guitar solo in history, but hey, it’s my first musical recording too!).

Transcript will follow soon.
