in progress Drought The Southwestern United States is the worst drought the region has experienced since records management began in 1895, according to a new report from the National Oceanic and Atmospheric Administration (NOAA) Drought Task Force.
The lowest total rainfall ever recorded in the Southwest (including Arizona, California, Colorado, Nevada, New Mexico and Utah) for the 20 months from January 2020 to August 2021 and third. A high daily average temperature was seen. Unprecedented costly “crisis, Report said..
Drought interrupts the 20-year decline in precipitation in the southwest, which is “probably natural” and artificial. Climate change Average temperature Burning highs, The report was found. Together, low precipitation and scorching temperatures reduced snow cover in the mountains of the region and increased water evaporation of the southwestern soil, leading to severe and persistent droughts.
Given the forecast of autumn rainfall, the drought is likely to last until 2022, and according to the report, the drought can last quite long if there is little rainfall in the area. However, even with natural increases in rainfall over the next few years, anthropogenic climate change still increases the risk of extreme heat. Forest fire, Increases both the likelihood and severity of future droughts, researchers said.
“The warm temperatures that helped spread this drought so severely and widely will continue (and rise) until severe climate mitigation is pursued and the region’s warming trends reverse (and rise),” the team said in their report. wrote. “2020-21 was an exceptional period of low rainfall, but the drought that occurred heralds a future in which the southwestern United States must now take steps to manage it.”
Meanwhile, the drought will continue to cause enormous damage to more than 60 million people in the southwest, and to the countless millions who depend on goods and services in the region, the report said. ..
“The economic losses associated with the drought in 2020 alone, excluding the losses from the associated wildfires, are between approximately $ 515 million and $ 1.3 billion,” the report said. With the addition of wildfires, the cost of this crisis will rise from $ 11.4 billion to $ 23 billion in a year in six states.
