Southwestern North American megadrought information
Ongoing megadrought in southwestern North America that began in 2000
Lake Oroville, the second-largest reservoir in California, fell to a record 24% of capacity in summer 2021.The drought that began in 1276 is hypothesized to have caused the abandonment of Cliff Palace and other Ancestral Puebloans settlements at the end of the Pueblo III Period.Modeled soil moisture changes at the end of the 21st century under three greenhouse gas emissions scenariosDrought area in the United StatesDrought area in CaliforniaA typical dry lakebed is seen in California, which is experiencing its worst megadrought in 1,200 years, and is therefore water rationing.[1]
The southwestern North American megadrought is an ongoing megadrought in the southwestern region of North America that began in 2000. At least 24 years in length, the drought is the driest multi-decade period the region has seen since at least 800 CE. The megadrought has prompted the declaration of a water shortage at Lake Mead, the largest reservoir in the United States. Climate change models project drier conditions in the region through the end of the 21st century, though climate change mitigation may avoid the most extreme impacts.
Furthermore, global La Niña meteorological events are generally associated with drier and hotter conditions and further exacerbation of droughts in California and the Southwestern United States and to some extent Southeastern United States. Meteorological scientists have observed that La Niñas have become more frequent over time.[2]
