Hottest in 12,000 years! But wait. . . .

As is not unusual, the BBC website loves to stress what serves its politics and enjoys ignoring, or embedding, the details that muddy the water of its pure train of thought. Here is a good example. First of all, geological time is not on their side - the past 12,000 years have indeed been a warming period. But scroll down and you will see that the BBC mentions but does not stress the fact that proxy data present significant problems in calibration. But this important qualification never gets stressed, and never gets into the mainstream of lay thought on the subject. Simply put, sets of data should not be mixed in scientific analysis without this being fully explained and the limitations recognized.
