...much for going gently into that good night. More than two years after announcing his retirement in a tearful press conference that left an entire state of Cheeseheads in mourning, storied quarterback Brett Favre shared the field with the Green Bay Packers again. Only problem: he played for their divisional rival, the Minnesota Vikings, in what was breathlessly touted as a revenge match against the team that thought the 39-year-old signal caller was washed up. Favre proved his critics and the Packers wrong, leading the Vikings to a 30-23 victory, throwing three touchdowns in the process...
This December, representatives from some 200 nations will meet in Copenhagen to tackle the problem of global warming. Their focus will be on limiting the emissions of greenhouse gases that come mostly from wealthy nations. The talks will build on the framework set by the Kyoto Protocol in 1997. This time around, the pieces are in place for a major confrontation between the U.S. and China. In the last century, the U.S. and the Soviet Union faced off in a Cold War that saw a massive buildup of nuclear weapons. Today, a new Cold War could develop...

The problem is clear: before it commits to reductions, the U.S. wants China to agree to limits - but the Chinese, who said this week they were ready to reduce the rate of growth of emissions by a "notable margin," rightly point out that Kyoto spares China and all developing nations from binding emissions-cuts targets unless they are compensated...
...been isolated examples of success growing jatropha. "Occasionally a tree has survived in a marginal area and produces quite a bit of seed with no [agricultural] inputs whatsoever. But there's a difference between that one tree and replicating it thousands of times in the field," he says. The problem with jatropha, scientists say, is that there is no proven, widely disseminated method for growing it properly...
...problem is, none of those promises came to be. "It was a combination of international hype and local organizations who were ... selling seeds at very high prices claiming that they were special certified seeds when really they were just seeds collected from old trees in the wild," Newman says. The plants also did not do well in arid conditions. "[The plant] was more fragile, especially in its initial establishment phase, than we thought," says Jan Van den Abeele, executive director for Better Globe Forestry, a Nairobi-based group that studies optimal conditions for planting trees in dry areas. And many...
