Resumen
The subject of Climate Change is here to stay for at least the rest of the 21st
century. The extent to which climate change can be expected; the importance in
its determination of anthropogenic factors, relative to natural causes; its impact
on world agriculture, migration patterns and economic growth; the costs involved
and the best practices to mitigate the consequences, are all still subject to
great controversy and remain in the realm of the speculative, in spite of specific
matters where a relative consensus has been reached, and despite media efforts
to show only the more alarmist view. It is this controversy that gives the name to
this essay, which advertently paraphrases former United States Vice-President
Al Gore?s movie An Inconvenient Truth.
