Holding alarmists to account: Professor Mike Archer | Herald Sun Andrew Bolt Blog

There’s a comedy begging to be written about the time this nation lost its head.

Snows of Mount Hamilton | Musings from the Chiefio

IMHO, the emphasis on “Grids” and “Boxes” ignores this very important point: It isn’t just the box perimeter that matters, it’s the elevations inside that box as well.

During the times I was looking at GIStemp, I’d noticed that GHCN had reduced the high altitude coverage. Thermometers had fled the mountains for lower elevations. This “locked in” a cold baseline and warming trend. Now those places can not be filled in with the correct temperatures, as the vertical atmospheric height has changed. The Four on the beach in California can not inform us about the recent changes in Mount Hamilton. Nor can the Andes be properly reported

This is a structural bias that is now locked into the GHCN. The only way to fix it is to put back in the thermometers at altitude. Until that is done, the GHCN is useless for describing what is really happening in the world. As all three major temperatures series (HADCrut, GIStemp, NCDC) are based on the GHCN in large part; they too are useless.
