Today's global warming scare from AP

The AP has a frightening story on the effects of global warming:

The harmful effects of global warming on daily life are already showing up, and within a couple of decades hundreds of millions of people won't have enough water, top scientists will say next month at a meeting in Belgium.....

"Things are happening and happening faster than we expected," said Patricia Romero Lankao of the National Center for Atmospheric Research in Boulder, Colo., one of the many co-authors of the new report.

So, you might ask, what are Ms. Lankao's qualifications for writing about how fast the climate is changing? Google her and you find that she is a sociologist.
