Professor Explains "Trick" to "Hide The Decline"

Very good video, even though you probably know all this. Via The Corner.

Among the important points never made strongly enough: the proxies show a temperature decline even though observed temperature has increased (supposedly). Ergo, we know, in the one period (about 1900 to the current day) where we have both proxies and systematic global temperature observations, the proxies fail to accurately predict current temperature. They're not even close, really. They really go off the rails in the past 30 years.

Ergo, since the one period where we can check these proxies against strictly measured readings, the proxies fail, and aren't anywhere near the actual readings.

Does this give the warmistas pause when they then rely on these proxies to yield accurate temperature data before 1900? And presume to give us a temperature read of the last 1000 years (or 10,000) years? Nope! Those numbers, they're very sure, are completely accurate, and so we know as an absolute fact temperature is now rising.

They're so sure of their new proxies that without any argument about it they read the universally-accepted Medieval Warm Period out of existence. See, that was purely a northern hemisphere phenomenon. We know this. Because we have these highly accurate proxies from the southern atmosphere.

Ah, yes. Those proxies that offer such an innaccurate prediction of current temperature you have to use a "trick" to "hide" them from the public.
