So as calories available increases, it causes my height to increase? I'm gonna need a new wardrobe... You've confused an individual trend with a trend of the aggregate maximum value. A couple of those may have a minor influence on the limit of my height, but increasing those factors has no effect on my height. Or how about my age? And don't forget other highly correlated values, like the number of movies or books published, Chinese population, cumulative deaths in war, and number of artificial satellites. There's a correlation of my age (and height) with each of those. Just two temporal trends that move in the same direction. No causation, though.
