Oregon is the #9 most drought-ridden state

Nearly one-third of Americans experienced a weather disaster this summer, giving them first-hand experience into a future of extreme hurricanes, wildfires, storms, and floods caused by global climate change. Data from the National Oceanic and Atmospheric Administration (NOAA) and NASA both show rapid warming in the 21st century, with the past decade being the hottest on record. According to The Washington Post, the cost of responding to these weather disasters is more than $81 billion per year.

Among those disasters were several significant, costly, and deadly droughts. Droughts are among the most destructive forces in nature—only hurricanes are more economically damaging to the United States. Destroyed crops ripple through the economy, with animal feed prices increasing, which can indirectly raise the price of meats and animal products like milk and cheese. The annual losses due to drought are near $9 billion per year. Droughts also contribute to wildfires, increasing the likelihood of ignition and making them more extreme when they do happen.

Stacker ranked each state and Washington D.C., based on the average percentage of the state land that experienced drought conditions in the 20-year period from 2000 to March 2021, using data from the U.S. Drought Monitor (USDM). The USDM categories drought conditions using a five point scale ranging from "abnormally dry," indicating some short-term crop dryness or a lingering water deficit, to "exceptional drought," a serious condition involving a water emergency that leads to widespread crop/pasture losses.

As the final portion of this list reveals, the West suffered the worst ravages of drought in the country on average over 20 years, and continues to suffer the most today—and Oregon is no exception. Much of Oregon is suffering at least abnormally dry conditions (80.7%), with 67.3% seeing moderate drought, 44% experiencing severe drought, and 12.5% dealing with extreme drought.
