However, Dr. Brown added, these kinds of droughts will have effects that are "even more extreme" in the future, given a warming and drying regional climate.
A few studies suggest deforestation and other land uses probably also warmed and dried regional climate by the Classic Period (1700-1100 BP).
The contrast in precipitation between wet and dry regions and between wet and dry seasons will increase, although there may be regional exceptions.

Rainfall was actually above average in all regions apart from south-west England, south-east England and western Scotland which were rather dry, though regional differences were not large.
Variables such as storage method of the dried herbs, cultivation conditions for the fresh herbs that are then dried and regional factors all play into the suitability of dried herbs and the amount when substituting for fresh herbs.
The analysis found that regional dry spells increased by 7% with 1.5C of warming but by 11% with 2C, while sea level rises by 10cm more in the hotter scenario.
In addition, investigations of an alluvial fan in the Paraná River valley provided evidence of massive deposition of sediments from a tributary of the Ivaí River onto the floodplain, which is associated with a regional dry period in the late Holocene as well as neotectonic control.
She will join James Morris, the UN Secretary-General's Special Envoy for Humanitarian Needs in Southern Africa, on a two-day mission to Malawi, which is one of the countries worst-affected by the regional dry spell, rising malnutrition rates, and HIV/AIDS.
Paleosol morphology and carbon isotope values of soil organic matter and pedogenic carbonates indicate a long-term shift toward regional drying or increased duration of the annual dry season through the early Pleistocene.
