Comeuppance

Jan Hoffman blew it. In this article, he or she refers to Orson Welles's 1942 film The Magnificent Ambersons as one of his "late classics", alongside Touch of Evil (1958) and Chimes at Midnight (1965).

What? "Classic", yes, but it was, in fact, the opposite of "late". It was "early". It was, indeed, the second feature he had ever made (although the first of many he watched others hack the shit out of, partially due to his tendency to mentally abandon projects after a certain period of time).

The moral, Senor/a Hoffman, is to not fuck with Welles fans. If you do, we will tepidly and politely castigate you on our unread weblogs.

Their world is just being collapsed

Interesting, though largely speculative: Oceans getting louder, "much of [the noise] generated by commercial shipping".

Researchers believe animals may use the ocean's natural "sound channels" to communicate over thousands of miles. The channel is created where dropping temperatures, which force sound waves downward, meet increasing water pressure, which forces sound waves upward. At a certain depth, the sound gets caught between the two opposing forces and bounds ahead with little resistance.

Researchers suspect that dumping a cacophony of new noise into this system isn't good. Southall said there's convincing evidence of a phenomenon called "masking," in which the increased ambient noise drowns out natural ocean communications.

[...]

Southall acknowledges the mountain of work ahead to come up with real answers about ocean noise. To illustrate the difficulties of applying the science to ocean life, he points to the beluga whale, which flees from ship sounds in the high Arctic, but moves toward certain vessels in Alaska.

He added that sound is perceived by ocean animals so differently than land animals that it's almost like a different sense, making it hard to apply what we know about the effects of certain decibel levels to ocean life.
