As the climate continues to change, the United States of America becomes a place with both devastating amounts of precipitation and deadly droughts. The east, recently Kentucky, is drenched in water. The west, however, is dry and sometimes even on fire.
The National Oceanic and Atmospheric Administration, found that the Eastern half of the country has gotten more rain, on average, over the last 30 years than it did during the 20th century, and at the same time, precipitation has decreased in the West.
Stronger downpours are a clear symptom of climate change. As the climate warms, increased evaporation pumps more moisture into the air, and warmer air can hold more moisture. That means when it rains now, it tends to rain more.
The US is not the only country experiencing such extremes. Intense precipitation patterns are being observed worldwide. Most of Asia has gotten wetter, and average precipitation has increased in Northern and Central Europe. The Mediterranean has gotten drier, and is experiencing water scarcity. Much of Africa and Eastern Australia has also gotten drier
Climate scientists are not completely sure if the changes in precipitation are a permanent feature of our warming planet, or if they reflect long-term weather variability. What we are seeing is largely consistent with predictions from climate models, which expect to see more precipitation as the world warms, with big regional differences. Wet places are expected to get wetter and dry places are expected to get drier.
