"When the data doesn't match the model - the model is wrong."
OR.....the data is incomplete. How many new maple operations have come into existence during the previous 25 years? How about farming innovations that resulting in improvements in efficiency, and yield?? I didn't see that info on the graph? And where was the breakdown that illustrated yield/ per geographic locations within the maple belt??
No?
Well then, since the data posted is incomplete, then any conclusions drawn from it are highly suspect, to say the least. You want to know if the climate is changing? Really want to know? Then stop listening to the politicians who tell you one thing, and avoid the scientists who are claiming the opposite.... run down to the southern reaches of the maple belt, and check in with some farm families who've been sugaring for multiple generations. Ask 'em to show you "the wall"... the spot where their fathers and grandfathers have been writing the dates of "first run" and "all done" for decades. Take some graph paper with you and chart it out. You'll have your answer.
Whether one chooses to bring that graph paper back with them to show others, or quietly wads it up and chucks it into the firebox of the evaporator, will have absolutely no effect on what it plainly illustrates.
