Climate disaster predicted

Under the heading of environmental news, Reuters reports that disaster is coming:

WASHINGTON (Reuters) - Global warming could send world agriculture into serious decline by 2080 with productivity collapsing in some developing countries while it improves in a few rich nations, a study reported on Wednesday.

So, what climate expertise is behind this study? The next paragraph reveals:

India, Pakistan, most of Africa and most of Latin America would be hit hardest, said economist William Cline, the study's author.

So, the study's author, Dr. William Cline of the Peterson Institute for International Economics, is not a climate scientist or any other kind of hard scientist: he is an economist.
