Summary
A study by AccuWeather experts suggests that the United States may experience reduced water availability, lower crop yields, and more drought if current climate trends continue. The study shows that over the last 70 years, U.S. temperatures have risen, with a decline in both humidity and effective rainfall since 1995, potentially affecting agriculture and increasing drought and wildfire risks.
Key Facts
- Temperatures in the U.S. have risen by 0.5°F over the past 70 years.
- From 1995, relative humidity has decreased by 5.3%, averaging 1.7% less per decade.
- Average annual rainfall has dropped by 2.7% since 1995, but heavy rain events have increased.
- 24-hour rainfall over four inches has increased by 70%, and over two inches by 23%.
- Declining rainfall effectiveness impacts crop production and water supplies.
- The trend suggests expanding desert areas and increased wildfire risks.
- Rising temperatures and less soil moisture contribute to higher air temperatures.
