The earliest and longest drought discussed in the literature is the "Altithermal Long Drought", [23] which some scholars now believe was in reality two severe shorter droughts (ca. 7000-6500 BP and 6000-5500 BP), separated by an interval.
A drought is a period of drier-than-normal conditions. [1]: 1157 A drought can last for days, months or years.Drought often has large impacts on the ecosystems and agriculture of affected regions, and causes harm to the local economy.
According to the NOAA Drought Task Force report of 2014, the drought is not part of a long-term change in precipitation and was a symptom of the natural variability, although the record-high temperature that accompanied the recent drought may have been amplified due to human-induced global warming.

The U.S. Drought Monitor is a critical tool for the arid West. Can it keep up with climate change? Hayley Smith. June 3, 2024 at 6:00 AM. ... How long that's expected to last, and why.
Drought has long been the norm for California. But the state had a historically wet winter, and El Niño is threatening again.
That lack of storms helped lead to exceptional drought last summer across the Golden State. This winter, rain is already well ahead of last year's pace and is filling reservoirs as a result.
The drought is largely driven by temperature, which increases the rate of evaporation, with some contribution from the lack of precipitation. The several wet years since 2000 were not sufficient to end the drought. Researchers calculated that without climate change-induced evaporation, the precipitation in 2005 would have broken the drought.
Drought conditions in the continental U.S. increased from 12% in June 2024 to 45% in October 2024, according to the U.S. Drought Monitor. July was "good," but the dryness really started to ramp up ...
