Last month, scientists at the Space Applications Centre in Ahmedabad in western India published a pan-India livestock methane-emission inventory, the first ever, which put the figure at 11.75 million metric tons per year - higher than the 9 million metric tons estimated in 1994. This amount is likely to increase as higher incomes and consumption rates put pressure on the country's dairy industry to become even more productive. (See pictures of China's cow town...
...Using the industry metric, which estimates that about three-quarters of current sales are replacement vehicles, demand will push past 13 million cars by 2012. O.K., so assume that some people will drive less, run their cars into the ground or - gulp - give up driving. You still don't lose much. What's known in the industry as "density" - the ratio of vehicles to drivers - continues to increase...
...gases pose a threat to human welfare, the EPA's finding could lay the groundwork for nationwide regulation of CO2 emissions - just as the EPA is require to regulate pollutants like smog-causing sulfur dioxide. But regulating CO2 will be immensely more complicated - the U.S. emitted over 6 billion metric tons of CO2 in 2007 from countless sources - and business groups have raised the specter of a meddlesome EPA using greenhouse gases as an excuse to regulate projects large and small...
...parlance of the U.S. Army, a hand-grenade explosion is a "significant act." So are small arms fire, improvised explosive device detonation and car bombs. The daily number of "sig acts," as the soldiers call them, is sometimes used as a metric to measure progress or regression in the counter-insurgency effort in Iraq. The definition of a sig act, however, is not fixed. According to some soldiers, some sig acts today (those without fatalities, say) never would have been considered as such a year or two ago. And the value of the metric is a matter of contention, even...
...ship was about a ton. Once that mass is broken up into smaller pieces, the atmosphere ought to do a pretty good job of incinerating it. Skylab did shower the Australian outback with wreckage during its reentry in the summer of 1979, but it weighed a whale-like 91 metric tons; Columbia weighed...
