Paul Kedrosky has a wonderful piece for the deep-thinking site Edge.org about shifting baseline syndrome. It explains precisely why thinking that we're living in some anomalous "new normal" is a little silly. We're always living in a new normal, and the cognitive challenge is to remember that things haven't always been this way, nor will they remain this way.
In 1995 fisheries scientist Daniel Pauly coined a phrase for this troubling ecological obliviousness -- he called it "shifting baseline syndrome". Here is how Pauly first described the syndrome: "Each generation of fisheries scientist accepts as baseline the stock situation that occurred at the beginning of their careers, and uses this to evaluate changes. When the next generation starts its career, the stocks have further declined, but it is the stocks at that time that serve as a new baseline. The result obviously is a gradual shift of the baseline, a gradual accommodation of the creeping disappearance of resource species..."
It is blindness, stupidity, intergeneration data obliviousness. Most scientific disciplines have long timelines of data, but many ecological disciplines don't. We are forced to rely on second-hand and anecdotal information -- we don't have enough data to know what is normal, so we convince ourselves that this is normal.
