6. East Coast of North America: New York, Philadelphia, Boston, Cincinnati, Pittsburgh

Cities in the eastern part of the United States — New York, Philadelphia, Boston, Cincinnati, and Pittsburgh — all recorded temperatures in the 70s on Feb. 20th or 21, each setting an all-time high for single-day temperature in the month of February.

7. East Coast of North America: Maryland

On May 27, 2018, torrential rains west of Baltimore dumped between 6 and 12 inches of rain on the towns of Ellicott City and Catonsville, Maryland, causing catastrophic flood damage throughout the area for the second time in three years. Based on historical records, there is a 0.1% chance that such extreme weather events will occur and their frequency in recent years is likely due in part to man-made climate change.

8. Mid-Atlantic: Virginia to New York

A slow-moving colossal blizzard in January 2016 dumped up to 3 feet of snow from Virginia to New York, causing around $1 billion in damage and the deaths of 55 people. According to the Regional Snowfall Index, the blizzard was the fourth largest Northeast storm since 1900. Some scientists say the blizzard is an example of human-caused climate change because it was an extreme weather event.

9. Northeastern United States

According to the National Climate Assessment, the amount of rain falling in the heaviest 1% of storms in the United States increased by 71% from 1958 to 2012 in the Northeast, the most of any region. The increases in heavy precipitation has led to runoff and caused major flooding events throughout the Northeast, as well as the Midwest and Great Plains. Such increases in rain activity are unlikely to occur naturally and may be due in part to human-induced climate change.

10. Southwestern United States: California, Arizona, Nevada

Severe to exceptional drought conditions proliferated in the American Southwest at the beginning of spring. Fish in the Rio Grande had to be relocated, and farmers along the Middle Rio Grande in New Mexico were told to expect half their irrigation allotment. The drought contributed to an abnormally intense fire season in northwestern Colorado and led to the first ever rationing of water usage along the Yampa River Valley in the basin’s history, as well as other serious impacts on people, agriculture, and wildlife in the area.
