摘要

The debate on global warming, framed on one side by those who see a long-term gradual warming of global surface temperatures and on the other side by those who see only small and potentially beneficial changes, misses a very important possibility. A real threat is that the greenhouse effect may trigger unexpected climate changes on a regional scale and that such changes may happen fairly quickly, last for a long time, and bring devastating consequences.
