The past three years have set records for billion-dollar disasters striking the United States, with 45 separate events. The long-term, inflation-adjusted average is 6.2 events per year, so the United States has nearly tripled that pace since 2016.
“Not only have many of these events rewritten the record books, but nearly all regions of the US were impacted in some way.”
The average global temperature has risen about 2 degrees Fahrenheit, or a little over 1 degree Celsius, since the 1880s. That puts us more than two-thirds of the way to the warming limit of 1.5 degrees Celsius that was set in the Paris climate agreement.
Record warmth was seen over much of Europe for 2018, which saw summer temperatures well over 90 degrees Fahrenheit — over 32 degrees Celsius — all the way up to the Arctic Circle. Record warmth extended along the Mediterranean and the Middle East, as well.
Extremely heavy rainfall events such as Hurricane Florence and the flash floods in Ellicott City, Maryland, stand out as examples of extreme precipitation that are consequences of a warmer climate. Warmer air can hold more moisture, making more available during storms.
Nine states in the eastern United States had their wettest years on record: Delaware, Maryland, Massachusetts, New Jersey, North Carolina, Pennsylvania, Tennessee, Virginia and West Virginia.
