...greenhouse dilemma illustrates the difficulty of setting policy based on uncertain projections of the future. Scientists generally agree that an unchecked accumulation of greenhouse gases will eventually lead to warming, but no one knows when it will start, how much will take place or how rapidly it will occur. The most widely accepted estimate is a rise in the earth's average temperature of 1.5 degrees C to 4.5 degrees C (3 degrees F to 8 degrees F) as early as 2050. An increase in the upper part of that range could produce disastrous climatic effects, including rising sea levels...
...voices of disabled Vietnamese soldiers are only a small echo of the sometimes hopeful but often disenchanted and uncertain views voiced everywhere in Vietnam. Fifteen years after the fighting ended on April 30, 1975, the country remains impoverished and embittered. While it has been at peace since most Vietnamese troops left Cambodia last September, there is great discontent over living conditions and an annual per capita income of less than $200, far below that of South Vietnam in 1975. Last year 75,000 boat people set sail for the refugee camps of Hong Kong and Southeast Asia, attempting to escape...
...male absolutes? The Einstein experts are unconvinced. At worst, they say, Einstein was a lousy husband. The fact is that we will never know; Albert and Mileva have fallen into some Pynchonesque black hole of history that claims the dead.

...believe that by dismissing the case, the Ad Board has left open the question of what constitutes "hate speech." The right to be hateful does not take precedent over the right to be free of harassment, and the Ad Board's response has left minority students of all groups uncertain about how much support the University will give us in cases of verbal harassment...
Savage has always had an uncertain political base in his district, a mostly black area that encompasses parts of Chicago's South Side and some adjacent working-class suburbs. Running against divided fields, he has never won more than 52% of the vote in a primary contest. This year his opponents rallied behind a single candidate, Reynolds, a former Rhodes scholar with support from a number of prominent blacks in the district. Savage may have decided that a low-road campaign of race baiting and anti-Semitism was the safest way to stymie a strong opponent. Even so, he squeaked...
