Which of the following statements is TRUE regarding the future risks of decadal (11-year) and multidecadal (35-year) droughts in the southwestern U.S. and Great Plains?
A) Although the future risks of decadal droughts are low for both regions, multidecadal droughts are expected to occur in both areas during the latter half of the 21st century. B) Models indicate that the southwestern U.S., including California, is more likely to experience these long-term droughts in the latter half of the 21st century, and much of the agricultural loss in that region will have to be offset in the Great Plains, where models indicate a very low probability of long-term drought. C) Models indicate that both regions are more likely to experience decadal and multi-decadal droughts in the latter half of the 21st century than during the latter half of the 20th century. D) Although El Niño patterns have caused short-term droughts in California and the Great Plains, neither region is expected to experience long-term droughts during the latter half of the 21st century. E) Fewer multi-decadal droughts are likely, but more decadal droughts are expected to occur during the latter half of the 21st century.
