So the criminal fraudsters at the heart of this substituted the temperature data for the tree ring proxy data for the most recent part of the graph, to maintain the hockey stick for all curves. And the Liberals were oh so pleased with themselves to repeatedly point out that the tree ring proxy date does not mean the claimed warming in recent years didn't happen.
If I was to be generous I'd say there was at most about two minutes worth of science in the film and the documentary put together. Yes retard we get that the thing that was hidden was not a fall in recent temperatures, but a fall in the temperatures extrapolated from the tree ring data proxy. No retard we don't think that the tree ring data means there has been a fall in recent temperatures. It is of course evidence of such a fall, but its pretty weak evidence when in conflict with the numerous more direct methods of measuring temperature.
No the point is, that if the tree ring proxy is inaccurate in the recent past it may be inaccurate in the far less recent past. If the tree ring data failed to represent "unprecedented global warming" in the recent past it may not represent "unprecedented global warming" in the far less recent past. the recent unprecedented global warming may not be unprecedented at all. just because the end of the hockey stick is accurate in absolute temperatures, doesn't mean the hockey stick isn't a lie, because its relative to warming in the past which can not be measured directly.
Now I'm not a climate scientist, but I would be very surprised if the tree ring proxies have not been used in the calibration of other temperature proxies. Undermining the even longer time period hockey stick claims as well.
