• States precipitation changes may differ not only between regions but also between different aspects of precipitation, such as totals and extremes
• Investigates changes in these two aspects in the world’s dry and wet regions using observations and global climate models
• Results show the number of days of extremely heavy rainfall or snowfall has been rising by 1 to 2 percent each decade in the world’s driest and wettest regions
• Finds similar increases are projected until 2100
