Other early notable droughts in North America include the Fairbank Drought of 500 BC [24] and the Whitewater Drought of 330 C.E. [25] [26] There were megadroughts in what is now the central and western United States, between 900 and 1300. [27]
The southwestern North American megadrought is an ongoing megadrought in the southwestern region of North America that began in 2000. At least 25 years in length, the drought is the driest multi-decade period the region has seen since at least 800 CE .
The pulse of the Colorado River has long served as a gauge of the American southwest's water supply, and a new study has found that the intensity of the current megadrought is a threat to its ...
Thanks in part to rising temperatures due to climate change, "extreme" or "exceptional" drought conditions are now occurring in 74 percent of California, while 72 percent of the western U.S. is ...
The 2000–present southwestern North American megadrought was the driest 22-year period in the region since at least 800. Both 2002 and 2021 were drier than any other years in nearly 300 years and were, respectively, the 11th and 12th driest years between 800 and 2021. [18]
Population growth. Since 2000, droughts have cost the U.S. around $160.8 billion, according to the NOAA.That figure jumps to $272 billion when accounting for destructive wildfires that are more ...
In the years 2000–2021 the southwestern North American megadrought persisted. Climate change increased temperature, reduced the amount of precipitation, decreased snowpack and increased the ability of air to soak humidity, helping to create arid conditions. As of 2021 the drought was the most severe in the last 500 years. [65]
