by Michael Tortorello in the New York Times, Wednesday February 9, 2011. Witty and informative, and masterfully swinging to read, on what is a very dusty subject in less artful and cheery hands.
Although she was working with inchoate historical data, Dr. Mahowald said, “Nobody has come up to me and said, ‘I don’t believe you.’ ” Climate change seems to be one source for all the new dust. Human land use is another. Anyone looking for a scapegoat — and that’s all of us, isn’t it? — can start with the droughts and desertification in North Africa, she said.
Alternately, I asked, have researchers considered the possibility that the dust might have come from under my bed? Recently, my wool Schlitz hat fell down there. When I retrieved it, the hat had grown a full, gray rabbinical beard.
“That doesn’t have anything to do with it,” Dr. Mahowald said, without even pausing to consider my hypothesis. Her study didn’t measure dust from human sources, like our burping tailpipes and pilling sweaters, she explained. “Dust is such a vague term. I’m being very particular here: soil particles suspended in the atmosphere.”
