An incredibly important study that first described in detail the effects of the Cretaceous mega-bolide on climate, leading to mass extinctions on a global scale. From the conclusion [p. 20]: "Our atnospheric radiative transfer calculations indicate that a total mass of aerosols between 1 and 4 times 10e+16 [100,000,000,000,000,000] g [Editor's note: or 220,462,262,184,878 pounds or 110,231,131,092 U.S. tons or, assuming the average weight of an automobile to be 4,019 pounds, 54,048,115,269 cars or 214 times the total number of automobiles in the U.S.] distributed globally over the Earth's stratosphere is sufficient to reduce the photosynthetically active solar radiation at ground level to 1/1000 of normal. An equivalent amount of dust could be deposited into the stratosphere as ejecta from an impacting asteroid between 0.4 and 3 km in diameter, or as the consequence of an Earth/comet collision or close encounter. The resulting darkness on Earth's surface alone would be sufficient to initiate the Cretaceous-Tertiary extinction mechanism hypothesized by Alvarez et al. if it persisted for at least one growing season. The superposition of other extinction mechanisms like a heat flash followed by substantial climate modifications, as discussed by Emiliani, would add to the stress situation in the biosphere. Because our results determine only the minimum required stratospheric aerosol mass to produce the darkness scenario, we find no contradiction between the estimate of Alvarez et al. of 10 ± 4 km for the asteroid diameter and our minimum-size estimate of 0.4 to 3 km. We extend, however, the number of impact craters on Earth that could possibly be related to the C-T event. Even a close eacounter with a Halley's-size comet or a sweep through an interstellar cloud becomes a plausible source for the deposition of 1 to 4 times 10e+16 g of fine-grain particulates into the stratosphere without producing any sizable impact crater.".
