Colorado’s Biblical Floods in Line with Climate Trends

The Boulder, Colorado area is reeling after being inundated by record rainfall, with more than half a year’s worth of rain falling over three days recently, reports Andrew Freedman at Climate Central. Daily rainfalls of 8 to 10 inches have created a 1 in 1,000 year event. Several people have died, many more are missing, and even more have been evacuated from the flooding. (As of this writing, 1600 homes have been known to be destroyed.  Numerous longstanding records have been smashed, including the all-time 24-hour rainfall record in Boulder. Extreme rainfall events have become more frequent across the U.S. during the past several decades in part due to manmade global warming. Increasing air and ocean temperatures mean that the air is generally carrying more water vapor than it used to, and this moisture can be tapped by storm systems to yield rain or snow extremes. The National Weather Service said that the amount of precipitable water in the air over Colorado was and is at record levels for September. This comes after a summer of moderate drought for Boulder, and Colorado’s most destructive wildfire on record.

This is how YOU can make a difference.
