surface would be unbearable
Note that though ocean currents transport some of the heat necessary to alleviate this imbalance, air does most of the work. Oceans are responsible for about one-third and air for about two-thirds. See Barry and Chorley,
Atmosphere, Weather and Climate.

get hurricanes only in the tropics
Ferrel was the first person to realize why hurricanes never happen at the equator: It's the one place on Earth where the Coriolis force doesn't operate. Air has neither the urge to turn right nor left, so it can simply tumble into local low-pressure holes without whipping itself up into a hurricane frenzy.

roll chaotically around the middle latitudes
A hurricane is typically about four hundred miles across, compared with nine hundred to eighteen hundred miles for a mid-latitude storm. Also, though hurricanes tend to blow themselves out in a few days, mid-latitude weather fronts can last a week or more. See Barry,
Atmosphere, Weather and Climate.

don't know what you've got till it's gone
A message that seems to have made its mark down the years. In 2003, I played this song to a group of Princeton juniors and seniors during a class I was teaching on environmental science writing and told them I'd give extra credit to anyone who could name the singer and song. In unison, they all chanted, "Joni Mitchell: 'Big Yellow Taxi.'"

Ibid., p. 124. Note: There were still some international rumblings. The infant United Nations Environment Program held the Vienna Convention in March 1985. It was modest in ambition, with only twenty signatories and no regulatory powers—nothing compared with what would follow the discovery of the ozone hole itself.

It was not until 1997 that women were allowed to winter there. The first woman visitor was back in 1973, but she doesn't really count. She was the wife of a ship's captain, who stepped onto the ice after the officers' dinner to be photographed next to the penguins in her evening gown.

Heath later claimed his group had already spotted the spurious data by the time Farman's paper was published, and had been secretly trying to interpret them. In any case, he had certainly missed his chance at one of the scientific scoops of the century.

for our eyes to see
Ultraviolet and infrared are other examples of electromagnetic waves; see chapter 5. But whereas they have wavelengths of tiny fractions of an inch, wireless waves can have a distance between successive peaks and troughs of several miles. Since the shorter the wavelength, the higher the energy, radio waves are the least energetic of all, which is why we can live in a world that is permanently crisscrossed with radio waves yet suffer no ill effects.

come to be called the Heaviside layer
About the same time, an American scientist, Arthur Kennelly, made a similar suggestion. Heaviside had earlier written a more detailed treatment of the idea and submitted it as an academic article to be published in the
Electrician,
but the article was never published. That could be why researchers at the time used the term "Heaviside" layer or at most, appended Kennelly's name to Heaviside's. See Ratcliffe's
Sun, Earth and Radio.
