On New Year's Day, let us contemplate signs of future weather. In my Findings column, I argue that "availability entrepreneurs" have been exploiting short-term weather in order to awaken the public to what could be a real long-term danger, global warming. Hurricanes, blizzards, floods, droughts, exceptionally hot years â all these have been linked to [...].
