How To Prove Global Warming: Ignore Cold Temperatures

If you wanted to make a case for human caused global warming you might decide to look at temperature records where the humans are. That would mean in the cities, of course. And you would see a clear trend: as the numbers of humans in a place rises, the temperature tends to rise too. It is called the urban heat island effect.

But what about temperatures in the outlying hinterlands? Say, the Canadian Arctic. Or the high Bolivian mountains. Since very few people live there, the urban heat island effect doesn't exist. But wouldn't these temperatures tend to bring the global average temperature down? Indeed they would. And that is why these outlying temperatures are being ignored in climate models or not even measured at all.

And that's the gist of revealing new research:

"NOAA . . . systematically eliminated 75% of the world's stations with a clear bias towards removing higher latitude, high altitude and rural locations, all of which had a tendency to be cooler," the authors say. "The thermometers in a sense, marched towards the tropics, the sea, and to airport tarmacs."

The NOAA database forms the basis of the influential climate modelling work, and the dire, periodic warnings on climate change, issued by James Hanson, the director of the GISS in New York.

That's one way of pinning global temperature rise on the humans - don't measure the places where they don't live. Because it's, you know, cold there.

Meanwhile, the Copenhagen Agreement is falling apart. Quelle surprise.
