What's even more ominous than the speedup is the fact that it's spreading northward. Between 1996 and 2000, says Rignot, glaciers started accelerating, but only up to the 66th parallel. Over the next five years, the speedup moved north to the 70th. "If it spreads even further north," says Dowdeswell, "the implications are that much greater...
...interesting political note: Eric Rignot, the lead author of the Greenland study and an accompanying report in Science magazine, works for NASA?s Jet Propulsion Laboratory (the glaciers? speedup was detected with a satellite). Just a couple of weeks ago, another NASA scientist named James Hansen claimed he?d been silenced by the agency for speaking out about evidence for global warming; the resulting furor led the NASA official who was involved to resign. Hansen?s commentary on the Greenland result appears here. And when Rignot was asked yesterday whether anyone at the agency had tried to shut...
Many scenarios for global warming, for example, invoke a speedup in the hydrological cycle by which water evaporates and then comes down as rain. The cooling produced by solar dimming, however, may slow the rate of evaporation, while higher up in the atmosphere the pollutants responsible for absorbing and reflecting sunlight are likely to interfere with the process that produces rain...
...many dual-career families, both parents are victims of what Williams calls "the great American speedup." The resulting stress falls disproportionately on mothers, who continue to shoulder the majority of child care and housework. When pressures reach the bursting point, married mothers, who earn 69% of what married fathers earn and may face gender-based hurdles to reaching their full professional potential, opt to reduce or eliminate their paid work...
...pediatricians, parents and teachers will tell you, this first sign of puberty seems to be occurring more often among six-year-olds and seven-year-olds than ever before. (Boys, as far as anyone can tell, are still growing up at their usual, slower pace.) Nobody can explain this speedup. Some even question whether it's real or anything abnormal. But if you suspect your first- or second-grader is blossoming too early, some basic information may help you sort through the confusion...
