MEXICO — Critical negotiations are under way here in Cancun, under the auspices
of the United Nations, to reverse human-induced global warming. This is the
first major meeting since the failed Copenhagen summit last year, and it is
happening at the end of the hottest decade on record. While the stakes are
high, expectations are low, and, as we have just learned with the release of
classified diplomatic cables from WikiLeaks, the United States, the largest
polluter in the history of the planet, is engaged in what one journalist here
called "a very, very dirty business."
