Die führenden Soja-Händler Brasiliens haben beschlossen, das seit sieben Jahren gültige Soja-Moratorium letztmalig zu verlängern. Es läuft bis Ende Dezember 2014. Dies teilten sie am 31.

Almost nine hundred years ago, in the mid-12^th century, the southwestern U.S. was in the middle of a multi-decade megadrought. It was the most recent extended period of severe drought known for this region. But it was not the first.

The second century A.D. saw an extended dry period of more than 100 years characterized by a multi-decade drought lasting nearly 50 years, says a new study from scientists at the University of Arizona. (more…)
