I have been watching a drop of water on the windowsill for the better part of an hour, and I have decided that the whole planet is doing nothing but this, everywhere, all at once. The drop holds the room upside down inside its curve. It holds the sky. This is what weather is: light passing through water and air and being bent, and us standing under it, astonished, keeping notes.
In London the air is 21°C and the sky has gone perfectly clear, which is not nothing – a clear sky is a decision the atmosphere makes, molecule by molecule, and today it has made it. The wind is dead still, zero kilometers of it, so the whole city sits inside a held breath. Cross the water to Paris, 21°C also, mainly clear, and you feel the same warm hand laid flat over both cities, though the humidity in Paris has dropped to fifty-two and the air there has the dry snap of a page turning.
Look west. New York at 22°C lies under an overcast lid, the humidity swollen to eighty-eight, the wind moving at eighteen kilometers an hour off the harbor. That grey ceiling is not empty; it is a suspension, ten thousand tons of water held aloft by nothing but temperature and spite. Los Angeles, 21°C and equally overcast, is stranger still: a humidity of ninety-five and almost no wind at all, two kilometers an hour, the whole basin sweating quietly under a marine dampness it pretends not to have.
Now the far side of the earth, where morning is already old. Tokyo stands at 32°C under a clear sky, the heat pressing down with a seventy-five percent humidity that turns the light thick as honey. Go to Cairo and it is hotter, 37°C, clear, the humidity a parched thirty-seven – desert arithmetic, where the sun subtracts water from everything it touches, including you. Mumbai at 28°C is the counterargument: a dense drizzle, the monsoon machinery running full tilt, wind at twenty-seven kilometers an hour driving the water sideways so that it does not fall so much as arrive.
Beijing is where the sky loses its temper. A thunderstorm, 26°C, humidity at eighty-six, the electricity in the clouds building toward that instant of release when the difference between one cloud and another becomes unbearable and leaps. I think a thunderstorm is the atmosphere confessing that it cannot hold still forever. Nairobi, meanwhile, sits calm at 24°C under an overcast that carries only forty-four percent humidity, a dry grey, the highland air cool and thin.
South now, into winter turned upside down. Sydney is 14°C, partly cloudy, the clouds torn into pieces that let the light through in patches. Buenos Aires shivers at 9°C under a light drizzle, the humidity a saturated ninety-two, the coldest breath on the whole rotating ball this morning. And Mexico City, high on its plateau, holds 14°C under a clear sky with the wind almost absent, four kilometers an hour, the thin air offering no resistance to the enormous cold light of altitude.
Twelve cities, twelve small weathers, and not one of them separate from the others. The warm air rising off Cairo will cool and sink somewhere; the water lifting invisibly from Mumbai's drizzle will fall as Beijing's thunder or London's future rain. It is all one system, one breathing thing, and we are inside it the way the room is inside my waterdrop – held, inverted, luminous, and utterly unaware of being watched. I put down my pen. The drop on the sill has evaporated. It has joined the weather.
