Global agriculture, already predicted to be stressed by climate change
in coming decades, could go into steep, unanticipated declines in some
regions due to complications that scientists have so far inadequately
considered, say three new scientific reports.
The authors say that
progressive changes predicted to stem from 1- to 5-degree C temperature
rises in coming decades fail to account for seasonal extremes of heat,
drought or rain, multiplier effects of spreading diseases or weeds, and
other ecological upsets. All are believed more likely in the future.
Coauthored by leading researchers from Europe, North America and
Australia, they appear in this week’s issue of the Proceedings of the National Academy of Sciences.

study by an international consortium of researchers has found that the
emerging market for carbon credits has the potential to radically alter
